Two New IPA's, Same Hops, Different Yeast

What a busy couple of months it has been. Unfortunately, I have not had time to write many blog posts and when I have had time, I felt like I didn't really have anything to say. At this point, I feel like most people that follow my blogs have read about my brewing philosophies for all the styles we have brewed, so even though we were brewing new beers, there wasn't necessarily anything new to say about them. Now we are brewing some newer beers that have some major differences from what we've become known for. This weekend we canned two new IPA's. At first glance, that doesn't sound  like anything new since we've brewed new IPA's and DIPA's every two weeks and we have canned them. This time though we experimented with new hops and after tasting the beers, I'm really anxious to share them with our fans. In fact, I think these might be my two favorite IPA's that we have released.

Both of these new IPA's are brewed with exactly the same hop bills but they feature two different, very distinctive yeast strains. These hops are new to us and probably will be new to most beer drinkers as well. We used Grungeist and Hallertau Blanc which are both German grown hops. One of the things that made this so fun for me is that German hops are rarely used in hoppy American ales. In recent years, German hop growers have been trying to gain traction with US craft brewers by breeding new varieties. Most of the new varieties are bred from Cascade and they feature flavors more similar to what we expect from fruity, citrusy hop varieties in America. Most of the new varieties are great for brewing new age pilsners, kolsches, helles, etc. but they haven't really gained much traction for the more extreme IPA's and DIPA's that are all the rage in America. Hops like Mandarina Bavaria and Hull Melon have the flavor profiles that we look for in IPA's, but they are too subtle to be featured in American styles in most cases.

Hallertau Blanc was the first German hop that I sampled and thought "This needs to be used in an IPA." My friend Tom from Hop Head Farms brought me a sample of a pale ale brewed at Three Floyds that used it and I was blown away by the wine like character that the beer had. It was more winey than any beer I've had brewed with Nelson Sauvin and the idea of brewing an IPA with it has been burning at me for months now. Grungeist was the second German hop variety that floored me and it was in a beer brewed by Pipeworks. It had an awesome floral aroma, gooseberry, pineapple, and lemon. Both of the hops are also low alpha acid varieties, so it's easy to get all that flavor and aroma without much bitterness at all.

The more I thought about those hops, the more I wanted to feature them together in IPA's. I also wanted to give brewing with Kveik (Norwegian Yeast that was handed down for generations of brewers) another shot. The idea of having the Sauvignon Blanc character from the Hallertau Blanc, the floral and berry flavors from the Grungeist, and the lemon-lime esters that can be achieved with Kveik, I thought we had an opportunity to brew something with completely new flavors. I also wanted to showcase the difference of Kveik and the English yeast we use in our New England style beers. One thing I always like discussing is that in every single beer we drink, there are approximately 1,000 flavor compounds at varying concentrations. Of those flavor compounds, 900 of them are produced by yeast during fermentation. The English yeast strain gives a notable peach ester and also is known for producing a lot of glycogens which in turn helps to create the soft, creamy mouthfeel. In contrast, the Kveik gives a huge citrusy aroma, ferments a beer very dry, and results in a very crisp, refreshing mouthfeel.

Now that the beers are canned, I couldn't be happier with how either of them turned out and I love that everyone that tries them will get to see how much influence yeast plays in the flavor of beer. They both have some wine character, pineapple, and berry, but the dry, crisp, lemony qualities from the Kveik make for an incredible contrast to the full bodied, peachy flavor of the English yeast. In addition to that, the more you drink of the beers, the more you begin to realize just how complex the hop flavor really is. The thing that I found most striking was that the terroir influence on the hops really shines. There is a distinctive floral quality that I find in all of the high quality hops grown in the Hallertau region. I remember the first time I noticed that flavor was when I was brewing Pilseners at Blue Pants and it was a distinctive flavor that I found in Mittelfruh, Hallertauer Tradition, and Hallertauer Gold. The same varieties of hops grown in other regions didn't have it. The flavor works great in these beers and the more you drink, the more it becomes noticeable and since the bitterness level of these IPA's is so low, you don't really have to worry about burning your tastebuds out and losing the ability to discern the more subtle flavors.

Citra IPA and Hoppy Pale Wheat Ale

It seems kind of crazy to me to think that we have brewed so many single hop beers at TBC, yet until yesterday, we hadn't released a single hop Citra beer even though Citra is the hop variety that we use the most. The reason we decided to do it now was because we stumbled across the best quality Citra that I have seen since 2009.

In recent years, Citra has been a bit of a problem for me. First, price jumped out of control and then when it was available, there seemed to be a weird onion/garlic character in half of the Citra I tried. It actually spawned a myth that over using Citra results in onion flavors... What's true is that low quality Citra has a tendency to display onion flavors. By the time Tombstone started production, I had learned which hop suppliers I wanted to work with and which ones I wanted to avoid, but the ones that I wanted to work with didn't offer Citra. Our first batch of IPA used Citra from the only supplier that had it that I felt that I could trust, but I knew that even with them I was taking a gamble. While it turned out well, it still didn't have the intensity of aroma that I remembered from the early years of Citra's development.

After we had been producing beers with that Citra for a few months, the supply ran out. We faced a tough decision... Should we stop using Citra and discontinue production of our IPA? Fortunately, as I came close to making that decision, one of my trusted hop suppliers contacted me to let me know that they got Citra for sale for the first time in their company history. Knowing that I could trust their quality, I asked for a contract for a few hundred pounds to get us through the year. When the first box arrived, I opened it up and immediately was ecstatic about our agreement. The aroma was the same huge punch of tropical aroma that I remembered from years previously before Citra production grew. If I had to describe the perfect harvest for Citra, it would be exactly what I smelled when I opened that box. Right away, I knew we had to brew a single hop IPA with it to show off what Citra is really capable of.

The Citra IPA features the same malt base that we use for our original IPA, but instead of Simcoe and Amarillo paired with it, this IPA has nothing but Citra. As always with our NEIPA's, it is very low in bitterness while still showing off a huge hop character from large whirlpool and dry hop additions. I feel like this beer really shows off what makes Tombstone beers special... Our never ending quest to use the highest quality ingredients, no matter the cost or the difficulty with which they are acquired. This is a difficult task as a small brewery that normally gets the last pick of a year's hop harvest, but thanks to our friends at Hop Head Farms, we have the best Citra available to us that we could ask for.

In addition to the Citra IPA shipping yesterday, we managed to get a "surprise" beer put on the truck for deliveries. I say it's a surprise because it was not a beer that we planned on brewing. Freight shipments are very difficult to deal with in a small town like Tombstone and two weeks ago, I planned on brewing another batch of Pilsener. The day before the brewday, the grains arrived, only to find out that half the order was missing. Due to our tight production schedule, if I didn't brew the next day, we would miss the opportunity to brew anything into that fermenter that was supposed to house the Pils. Instead of skipping a brewday, I went through the ingredients we had and found that I could brew a Pale Wheat Ale.

Pale Wheats seemed like they were the style of the future years ago when 3 Floyds released their awesome version, Gumballhead back in 2003. For the next few years, a lot of breweries brewed their versions of Pale Wheat Ales, but frequently, they left a lot to be desired. It's a style that I have enjoyed many times but drain poured more often. I've wanted to take a stab at one for a while now, but hadn't thought of brewing since TBC opened until we brewed Biffhorific Amber. After brewing the Amber, I couldn't help but think "What if Pale Wheats made a resurgence?" As I went through our material inventory, I was thinking to myself "This is my chance! Matt isn't here to tell me no!"

Our version is similar to a New England Style Pale Ale... Low bitterness, huge aroma, hazy, soft, creamy mouthfeel, and lots of esters. It was brewed with Amarillo and Simcoe and fermented with our IPA yeast strain. It's more drinkable than an IPA, but has much more hop aroma than your typical pale ale. The result is something that I would love to see more breweries producing and hopefully it's something that enough people will enjoy that it won't be a one time beer for us. I personally would love to have it available in cans for those late summer hikes in Arizona. Cheers!

Insanity Ensues: Canning, Fresh Hop Ales, Hop Selections, GABF, Oktoberfest, Pils

As I began to write out a proposed production schedule last week, I quickly realized that I was signing myself up for a hell of a couple of months. It seems like every idea I've had in the last year though, the more I'm excited about it and the better of an idea I think it is, the more of a pain in the ass it is. As we get closer to our canning line arrival, the more ridiculous the schedule becomes. As it would be, the upcoming beers and events have me more excited than I think I've ever been about what we've got on the horizon.

Perhaps the most exciting bit of news is that our canning line ships tomorrow! The canning line was something that we've been talking about since my first interview with Matt and something we've been wanting since we opened. As I look back on the first year's worth of our beer evolution though, I am actually a little bit relieved that we took this long to get the line...

I've been proud of every batch of IPA that we've brewed and while I originally thought that the first batch we brewed was as good as I could make it, every batch has actually received very minor tweaks to get us to this point. When I say minor things, it really has been extremely small tweaks... The first batch had a different water chemistry that left a little bit of a mineral character (which was intentional at the time, but after experimenting with water chemistry in other beers, I realized there was a better way to brew this beer) in the final product and has since been altered to make the mouthfeel as soft as possible. The fermentation temperature and yeast pitching rate were changed a few batches ago making the beer just a little bit juicier. Most importantly, in our first months we were working without hop contracts, buying everything from other breweries. While we were very selective about the breweries that we bought from and we took into account which hop growers and suppliers they bought them from themselves, we have since been able to source our hops on contracts from the two hop suppliers that I consider to be the best in the country. The batch that is in the fermenter now and getting canned on August 9th is undoubtedly the best batch that has been made yet. I think the beer in the tank now is the peak of what our IPA can be and it comes at the perfect time as it will be the first batch to go into cans. In addition to the IPA being canned on August 9th, one of our other most popular beers, Dank Fruit, will be canned on the same day. One week later, Over and Out (hoppy sour dry hopped with Citra) will be available in cans. The next canned beer after the first round will give us the opportunity to really show off our new hops with as Single Hopped Citra IPA.

After the first round of beers, it won't be until the end of August that we can the Citra IPA because of our competition schedule. We entered our Pilsener, Kellerbier, Oktoberfest, and one of our upcoming Wet Hop Pale Ales into the competition and the lagers need to be brewed immediately after emptying the batches of canned beers so that they can have enough time to condition before the competition. This batch of Pilsener will be the last time for a while that we brew the same Pils recipe and will also be our first Pilsener batch in cans. It will kick off a series of experimental German style Pilseners which should be canned about every 3 weeks starting in late October.

The other lager on the schedule, Oktoberfest, is one that I'm particularly excited to brew and compete.  After Pilseners, Oktoberfests are probably my next favorite style to brew and thanks in large part to Sierra Nevada's Oktoberfests the past few years, American craft beer drinkers have really started to appreciate the pale Oktoberfest style that I prefer to brew over the amber colored O'fests that dominated the craft brewing landscape for so many years. The way that I prefer to brew Oktoberfests had been more common in Germany for many years, but not too many versions of the style have been exported to the USA which has led to the misconception that O'fests are amber colored, sweet, malty lagers. Our Oktoberfest will feature all traditional German ingredients including Vienna and Munich Malts from Bamberg. While the color may be pale, the rich malty characters do still dominate the flavor profile and the lager yeast we use is the same strain used by one of the oldest, most popular breweries in Bavaria which creates a ton of flavorful esters but still leaves a super crisp finish.

Around September 1st is when the brewing schedule really becomes crazy... We are planning a fresh hop festival for the 3rd week in September which will feature the release of 3 different fresh hop beers. We are going all out for these beers in a way that many people might consider to be a bit silly. Our distance from the best hop farms in America be damned, we are not allowing that to deter us from acquiring the best quality fresh hops in the country. On September 1st, Amarillo is being harvested in Oregon, being put immediately onto a plane, and arriving in Tombstone in less than 12 hours from the harvest where I will have a full kettle waiting for immediate use of these hops. On September 7th, Chinook and Cascade from Michigan will arrive in the same manner which will allow us to dry hop the Amarillo Pale Ale with fresh hops and again, a full kettle will be waiting for these hops immediate usage. The Chinook from Michigan is particularly exciting as our growers there have discovered that their unique soil conditions and climate make some intensely pineapple-y Chinook free of the spicy, pine characters that are normally exhibited by Chinook grown in the Pacific Northwest.

For the Amarillo Pale, it will feature 100% fresh hops. To feature nothing but fresh hops is actually a fairly uncommon practice due to the logistics of the schedule. Fresh hops really need to be used as quickly as possible (most people agree less than 24 hours), so dry hopping a beer with fresh hops only works if you use hops from two separate harvests. Most fresh hop beers use them in the whirlpool or the dry hop, but not in both and if used in the dry hop, they rarely get packaged due to the incredibly short shelf life. Because of the short shelf life, anything that is not sold at our wet hop fest will be distributed and available at retail accounts less than 72 hours after the cans are filled.

Immediately after these fresh hopped beers are dry hopped, I'll be making a super quick trip up to Portland for an afternoon to select our Amarillo lots for next year. This is something that I consider to be critical for high quality hoppy beers and will serve to help us take a giant leap forward in our hoppy beer quality for the 2018 brew year. I never realized just how important lot selections are until I did my first one last year for Cascade which was the main hop in our highest rated beer this year. With lot selections, it allows the brewer to get one step further up the chain and closer to the growers. What a lot of people don't realize is that a single variety can taste completely different from one grower to the next and that the differences can be large enough to make the same variety from different growers be completely unrecognizable. By doing a lot selection, we are getting the hops before the lots are all blended together so that we can ensure that we only have the very best of each variety without "filler" lots diluting the quality. While that does hurt the year-to-year consistency, it guarantees that we only ever have the absolute best available for each year.

Right when I return from the hop farms we will begin packaging the wet hop beers, throw a wet hop party, brew a round of beers that will feature an oak fermented porter, ESB, and Amber for draught only so that we can have some variety on our menu for our first anniversary party. After brewing those beers, we'll have another quick trip to Portland to select our Idaho 7 lots for 2018, followed by a final round of beers before our first anniversary which will be celebrated on October 21st with Double Dry Hopped IPA, Another Exercise in Mediocrity, and Little Baby Wyatt all in cans.

On Deck: Amber Ale

It seems that everytime I sit down to write a blog post, I know pretty much what I want to say. However, I never know how to introduce it. I never claimed to be a writer... I'm just here to make beer and tell people about it, so for this one I'm just going to jump right in with a commentary on our new Amber Ale:

Everyone that has been following craft beer for the last few years can easily tell you the number one selling craft beer style in the USA is IPA. However, not many people would accurately guess the second best selling style. Depending on the study (and excluding studies where Shocktop and Blue Moon are included as craft beer), the second most popular craft style is either Pale Ale or Amber Ale. For some reason though, Amber Ales seem to get a bad reputation as being "beginner" or "gateway" craft beers, despite the fact that there are some truly terrific Ambers being brewed that can appeal to even the most advanced craft beer drinkers.

I'll admit that there was a time when I fell into the bias against ambers, but I think that part of the reason is that "Amber Ale" has really become a catch all category for anything darker than a pale ale and lighter than a brown ale. Many breweries have fallen into the trap of "We need to have something to please the ________ crowd" mentality and as a result, we see a lot of boring examples of a few styles with Amber Ales potentially being the poster child of boring beers. It seems that the formula for an Amber Ale lately has been to make something very sweet, loaded with crystal malts, little to no hop aroma/flavor, and around 5% ABV. For a while though, the trend was to make Ambers with complex flavors and a balance with hops in mind. In fact, even Anheuser-Busch got in on it with their American Ale in 2008 which was an Amber Ale loaded with Cascade.

As the style has kind of slipped more towards these sweet, malty examples, I started to think about what the style would be if it had continued down the path that pale ales and IPA's have. The three Ambers that I think of as the quintessential American Amber Ales being Bell's Amber, Modern Times Blazing World, and Troegs Hopback Amber, I couldn't help but wonder what would happen if the style followed the same path that those breweries went with more hop forward examples. With that concept in mind and following the trend of the New England style IPA's, I decided to explore what I think of "Biffhorrific Amber." Essentially, what would have become of the Amber Ale style if it had followed the trends of Pale Ales and IPA's.

For our Amber Ale, I applied a lot of lessons learned from our NEIPA's in regards to hop schedule, water chemistry, yeast strain, and mouthfeel. It will not be hazy like a New England style IPA (mostly because hazy amber beers just look really gross), but it does feature the same velvety mouthfeel, low bitterness, and (relatively) large hop aroma. Looking at old Amber recipes, one thing that stands out is how much higher the hopping rates were for Amber Ales at the beginning of the most recent craft beer boom. The hop dosing rates were nearly identical to those of Pale Ales. This was at a time when most pale ales featured 1.5 lbs of hops per barrel and IPA's featured around 3 lbs of hops per barrel. Now, as hopping rates have increased, our pale ale recipe is more in line with what many people think of as hopping rates for IPA's and our IPA's reach DIPA territory. I wanted to follow along with that concept in my theory of the "Biffhorrific Amber." As a result, this beer is loaded with the classic Amber Ale hop: The last of our award winning Cascade hops. It is then dry hopped with Citra which brings the total hop usage rate up to approximately what would have been common for an IPA a few years ago, however we also followed our modern hopping schedule which attempts to minimize bitterness. This Amber is surprisingly aromatic with huge tropical fruit aromas from the hops, lots of peach esters from the yeast, complimented with a pleasant biscuity malt flavor, and no cloying sweetness. This experiment in the alternative future from Amber Ales of 2008 has been a lot of fun for me and I hope that our consumers enjoy it as much as I have!

Continuing to Roll Out New Beers

It seems like every time Matt and I get the opportunity to get out of the brewery, hang out with other brewers, and stay up late drinking beers, we have the best brainstorming sessions about the future of Tombstone beers. Every time we get these chances, I always come back super excited about what we've got coming up. Our most recent opportunity to have this time of marathon brainstorming session happened this last weekend when we went up to Phoenix for a beer dinner followed up with our first collaboration brew with Wren House and Pueblo Vida. Getting to brew a collaboration with these breweries that we have so much respect for was a great time, very educational discussing how we each do things a little bit differently, and it was awesome to have the opportunity to hang out with other brewers instead of continuing our feeling of isolationism so far away from the brewing action in Phoenix and Tucson.

When we got back from our trip, I was looking forward to sampling our most recent round of beers which had been dry hopped just before leaving town. Typically, I like to write blog posts the day of the brewday or a few days before brewing. However, I struggled a lot to write this post. Each time I thought about what I wanted to write, I ended up going on multi-hour tangents in my head about the use of the word "session" and how "Session IPA" is admittedly a dumb name for a style, but also how the basis of people's arguments about using the word is also kind of ridiculous. Unfortunately, I'm not going to be able to make myself write this blog post without a rant first... If all you want to do is read about the beers we brewed, skip ahead a few paragraphs!

There seems to still be a lot of discussion about whether or not Session IPA is a style with some people claiming that a Session IPA is really just a pale ale, others saying that "session" is defined as being less than 4.5% ABV, low IBU, mildly carbonated beers because that's the expectancy of English session ales, and others blindly touting that it's clearly not a style because the BJCP doesn't recognize it.

Starting with the last argument... The BJCP guidelines exist as a way of giving parameters to a style. If styles were never invented, the BJCP would never create guidelines. The BJCP also has a lot of issues with their guidelines that spread misconceptions about various styles and they exist for competition use. I brew beer that I think is going to taste great and if it happens to fit into a style guideline, we will consider competing with it. However, I would never sit down with style guidelines in front of me while I develop a recipe with the goal of brewing a style within a flawed system's parameters.

As far as the definition of session in England: I hate to be "that" guy, but... this is America. Basically since the beginning of craft beer in America, the overwhelming majority of American ale styles have evolved from English styles. The most obvious differences typically include higher alcohol content, more IBU's, and higher carbonation levels. Styles like pale ales, IPA's, and brown ales have entirely different expectations between American and English styles. The only way they're being differentiated now is when people specify which regional style they are attempting to brew. So if we continue with American craft brewing traditions, should we just start saying "American Session Ale" and then we can agree that the word has different meanings when used in that context?

The most reasonable argument for people saying that using Session IPA as a style name is that the style is really just a pale ale. While I understand why people would say that, I do think there is (or should be) a notable difference. When I think of the classic American Pale Ale, like Sierra Nevada's, those types of beers are really well balanced. But with a Session IPA, I think the balance should shift towards being dramatically more hoppy. In my opinion, the goal is to take an IPA and pack the same intensity of hop flavor into the beer, but bring the alcohol content down to a range where you can drink more of it without becoming too intoxicated after 4-5 pints.

With my highly opinionated view on the style, I set out to brew a session IPA that I felt would be noticeably different from a pale ale, less than 5% ABV, and fits within the standards that our customers have come to expect from our IPA's. The problem that I think a lot of brewers face when attempting this style is the perception that low ABV beers are watery. I take a lot of pride in the soft but full mouthfeel of our IPA's and I wanted to create this beer to continue on with that. As a result, we used a very flavorful Pilsner malt that gives off a slight honey characteristic, increased the ratio of oats used in this beer, used very soft water, a high mash temperature, and a very small amount of dextrin malt to make sure that there would be residual unfermentable sugars to give the beer body. My thought was that if I gave the hops a big enough stage, I'd be able to use a higher quantity of hops per barrel than if I had brewed this with the same techniques that we brew our higher gravity hoppy ales.

With the malt backbone in place, I began working on the hop bill. We were so impressed with the intensely peachy flavor we got from Idaho 7 in our pale ale that I decided to make that a feature in this beer too. I paired the Idaho 7 with another new hop variety: Cashmere. The Cashmere beers that I've sampled have all had a great cantaloupe/ripe melon flavor that I thought would pair perfectly with the peach aroma of Idaho 7. Keeping in mind the difference in balance that I believe sets apart Session IPA's from Pale Ales, I decided to revisit some old wisdom, but this time with a twist.

When I first began brewing IPA's in 2009, the most common advice for balancing an IPA properly was to use a specific IBU to gravity units ratio of 1:1. For example, if the beer had a specific gravity of 1.060 then the target IBU's should be 60 IBU's. As the trend has shifted in the last few years to lower bitterness with more hop flavor and aroma, I knew that this was a beer that could easily be considered unbalanced if the hop schedule wasn't perfect. In the past couple years, I've actually begun to think of IBU's as a side effect of hop additions rather than the primary goal of hop additions. I believe that a third unit should be brought into play that could be referred to as an "Aroma Unit." The small hang up with trying to maximize aroma units is that the more aroma you try to achieve from hops, the more bitterness you will get as well. I ended up shortening the contact time for the hops by decreasing our whirlpool time to stop the utilization of bittering acids while maximizing the oil extraction.

After sampling the beer for the first time yesterday, I'm very happy with the end results. The beer is 4.9% ABV, extremely aromatic, has really awesome head retention, a full, creamy mouthfeel, and is very juicy, almost like candied peaches. I believe that it holds up very well to the standards we've created with our IPA and that it will be a great alternative for people at a bar when trying to hang out drinking with friends for longer periods of time than would be possible with the IPA.

The second beer brewed in our most recent round of 3 beers is a new and improved Double IPA. The first batch of Double IPA was a beer that I enjoyed a lot, but I felt that it was missing something. It was like the amarillo in that recipe couldn't get out of the shadow of the Simcoe and Citra, so it really didn't bring anything to the beer. It was a strange thing to notice since the original DIPA used the same hops as our IPA and we don't have that occurrence with the regular IPA. This time around, the Amarillo was replaced with Mosaic lupulin powder for the dry hop. The use of Apollo hop oil, plus an extra bag of oats really put the finishing touches on the original recipe. The aroma is incredibly intense from the sample I pulled yesterday and although it is 8.2% ABV, the drinkability remains very good.

The 3rd beer is another new beer for us: Coffee Milk Stout. The coffee being used is a great Ethiopian coffee from Ground Control which gives a really nice low level of roastiness paired with an intense blueberry coffee flavor. I'm typically very picky about coffee in stouts because I frequently find them to taste like green pepper after a short period of time. Testing this coffee in a cold brew, we got the intense blueberry flavor and none of the acidic, tannic, or peppery flavors that I find off putting in beers. At 7.5% ABV, the base stout is thick without being overly sweet or cloying. I can't wait to try the finished beer after the coffee has been added.

All 3 of these beers should be ready by early next week, so if you're one of the people saying that our beer keeps disappearing too quickly before you have an opportunity to get it, stay tuned around Tuesday or Wednesday to find out where these will be available!

Barrel Society Update

With all the interest in our Barrel Society, I thought that I would go ahead and try to answer the most common questions all in one place
:
First of all, I want to give a big thank you to everyone that has signed up so far! We're off to a really good start and with the interest we've had, we're starting to get a better picture of just how big we can make this. Today we went ahead and ordered two 40' refrigerated shipping containers that we are going to use as our first barrel facilities! In each one, we should be able to house at least 75 barrels easily and with a little bit of modification, we could stretch that up to 105 barrels. It is going to be a long time before we have a need for 210 barrels, but we wanted to have two of them so that we can keep our funky beers separate from the clean beers.

Probably the most asked questions have been about what beers will be released through our barrel society program. The reason we haven't released an official list is because we want to remain flexible. Every day we are looking for more sources for barrels and certain types of barrels are unpredictable in their availability. If a rare type of barrel pops up for purchase, there is a good chance that we will be buying it even if we don't necessarily have a beer planned for it. As a result, we don't want to release a definite list of beers and then find a more exciting type of barrel randomly become available without the flexibility in the production schedule to buy it. Our goal is to always find the absolute best barrels and if something super awesome comes available, I would hate to miss the opportunity to use it because we are committed to a predetermined list of promised beers.

That said, there are a few beers that we will definitely release that we can go ahead and disclose. The first beers that will be released to the Barrel Society will be an English Barleywine aged in Port, Red Wine, Woodford Bourbon, and Woodford Rye Whiskey barrels. We will also have our Imperial Stout with Piloncillo aged in Woodford Rye Barrels. These will all be ready in about 2 months and will be released to everyone that signed up for the Basic Membership. Each of these initial variants will be just about guaranteed to have extras after the allocations, so barrel society members will have 3 months of exclusive access to the extra bottles.

For our Funky Bunch members, we have between 3 and 6 months for the first allocations to be ready and the first release will include a Sour Wheat aged in toasted oak with Mango and Sour Cherries. We also have a 100% Brett fermented beer using a proprietary Brett Blend that gives intense pineapple and stone fruit flavor. That beer is now aging in Sauternes, Chardonnay, Toasted Oak, and Charred Oak barrels. We are also working on setting up a small yeast lab (in my home office!) where I will be able to propagate wild yeast strains and bacteria for the Funky Bunch. One idea I have is to cultivate yeast from the world's largest rose bush, which just happens to be in full bloom right around the corner from the brewery, and use it in a fruited sour.

For the top tier of membership, I'll be picking my favorite barrel from the barleywine variants and transferring that barrel into a second barrel of the same type. It is likely to be one of the Woodford Rye barrels. That barrel will age for just one month to take on more of the flavor of the whiskey before being transferred to a 3rd barrel which will be an unused, charred oak barrel where it will age for 3-6 months. If a triple barrel aged barleywine isn't exciting enough for you, one of the beers that is planned (and not yet brewed) will go through a similar process. It will be a HUGE imperial stout that will never touch stainless steel after the boil. It will be fermented entirely in new toasted oak barrels where it will ferment for 3-4 days before being transferred into a variety of barrels (including, but not limited to: French Apple Brandy, Bourbon, and Armagnac) for extended aging. Once again, I will select my favorite barrel and transfer into a second one of the same before transferring into a charred oak barrel... a quadruple barrel aged Imperial Stout.

While all of the transferring of barrels will be a lot of work, I believe it is going to be well worth the trouble. I got the idea about a year ago when I was working on a presentation about advanced dry hopping techniques which included a theory I've had about how to achieve the "complete" aroma of hops. That theory is based on the fact that every hop addition that you do has a trade off. The basic thought is that kettle hop additions destroy certain compounds in order to create other compounds and that the lost compounds can be reintroduced to a beer with post-boil additions and pure hop oils. Then when a beer is dry hopped during fermentation you get some bio-transformation of hop compounds meaning once again, the compounds that were transformed are lost and can be reintroduced at a later point in the process and then when serving beer, hops can be infused to capture the most volatile of compounds that would never survive the conditioning time frame, thus achieving and maximizing every possible hop flavor compound being present in the glass.

Around that time, I was working hard on planning the barrel regimen that we will be using and I started thinking that the same principles could be applied to the barrel aging process to create the "complete" barrel flavor. My thought was that the first barrel being used for primary fermentation would lend a very low level of barrel flavor that would mostly be vanillans and a lightly smoky phenolic character. More important than the flavor of the barrel itself though, the yeast will behave differently in a barrel fermenter due to the different dimensions and the micro-oxygenation that occurs. I've often thought about how almost every brewery in the United States uses the same basic fermenter design and how differentiation can be achieved by changing the shape and size. In a barrel, there will be very little pressure put on the yeast and as a result, the esters produced will be of much greater intensity than in cylindro-conical fermenter. In addition, the yeast will produce more glycogens which will act to enhance he creaminess of the mouthfeel and create a fullness that can't be achieved in stainless steel.

The next barrels being spirit and wine barrels will impart a lot of flavor of the spirits themselves, but some of the flavor will have already been "taken" from the barrel, so the final conditioning barrel is an unused barrel that will bring back those lost compounds. In a new barrel, the amount of barrel flavor is very intense and with all the enzymes in beer, it only takes 3-6 months to impart all of the character of the barrel. Since we will have already taken flavor compounds from a toasted oak barrel during primary fermentation, we will use the charred oak to achieve a greater depth of flavor and we will be able to specify the level of char with our cooperage to match the flavors that we want to pair with the individual beer.

This is all super exciting for us and the daydreaming about what we can produce for our barrel society members is non-stop these days.

Upcoming Beers for March: Kveik, Pils, Gose, Dry Hopped Sour and more

After a crazy month in February packed with events, bottle releases, and our taproom grand opening, I'm excited to get back to just focusing on brewing in March. In the coming month, we've got the beers that I've been most excited about brewing ever since we started brewing back in October. While we've had a blast brewing the hazy Northeast Style ales, I'm ready to start adventuring into some other styles and trying out some new things.

The beers that will probably be the most unique beers that we've produced thus far will be fermented with some really interesting yeast, also known as kveik. If you've never heard of kveik, there have been some really cool articles written about these yeast strains, which come from Norway and were used by Norwegian farmhouse breweries for many generations. These yeast strains have a really interesting back story where the yeast was typically kept within a family brewery and was saved in dried yeast rings in open air. While that sounds like a method that would harbor contaminants, and when you consider how old the yeast collections are, lab analysis has confirmed that various breweries have managed to avoid contaminants and that the yeast strains have evolved very little. What's interesting to me about that is that these yeast strains are known to have been passed from brewer to brewer with very basic methods, no labratory equipment of any kind, the yeast was spooned from beer into glasses, stored for months, and reused for centuries. Now with modern technology the cultures are analyzed and found to be pure Saccharomyces yeast cultures, no bacteria, no brett, etc. More info can be found here if you are interested in reading more about the lab analysis.

Recently, a few small yeast labs in America have begun to propagate cultures of a few kveik strains and the beers are getting rave reviews. The flavor profile from these strains is described as slightly earthy with pronounced citrus esters, most commonly being described as an orange peel flavor. To add to the intrigue, instead of fermenting in the normal ale temperature range (about 60-72 degrees F) the kveik strain we're using is known to ferment well up into the high 90's, create a very dry beer, and maintain a clean fermentation profile, free of phenols or fusel alcohols. Even more bizarrely, after finishing fermentation the yeast falls out of suspension quickly and is described by many of the early users as being the most flocculant yeast they've ever brewed with.

The first beer we'll be brewing with the kveik is slated to be an IPA with our award winning Cascade hops, Lemondrop, and Citra: basically all of our most citrusy hops to compliment the citrus esters from the yeast. Unlike our normal IPA, this beer should be very clear in comparison to what our customers have come to expect from us. It will also be very dry, so we will use a generous amount of flaked oats to help improve the mouthfeel.

After harvesting the yeast from that first batch, things are going to get fun. We will reuse the yeast in a sour, salty interpretation of Gose and we'll also brew another dry hopped sour with it. This time, instead of going with a lightly tart acidity the way we did with our first dry hopped sour, we will be more aggressive with the acidity on these batches. The type of lactobacillus we're using for these (L. Plantarum) is notable for giving a very pleasant acidity and creating a bit of a citrus flavor as well. While most yeast strains do not create much of an ester profile in sour worts, I'm hoping that we will still be able to get the orange peel or lime esters from the kveik yeast by sticking with a low pitching rate and fermenting all the way up near 100 degrees.

While the beers fermented with kveik are probably the most exciting to talk about, the beer that I'm actually even more excited to brew is a German Style Pilsener. While in brewing school, I dedicated my time in Germany to learning as much as I could about German Pilseners. Upon my arrival in Germany, I was actually not a big fan of the style, but drinking Augustiner Pils was a real eye opener for me. With perfect clarity, an extremely pale straw color, fine carbonation rising up to form the perfect foam in a footed Pilsner glass, their beer was highly aromatic, with lemongrass aromas, and insanely drinkable. After doing some research, I learned that their Pils was actually hopbursted with Hallertauer Mittelfruh, which is a pretty unique technique for a German beer. I would consider that beer to be the perfect German counterpart to an American Pale Ale as far as the perception of hop aroma.

We'll be using the lightest color Pilsner Malt available from Weyermann Malting. Their malts are great because in addition to being extremely pale, the rich, sweet flavor of their Premium Pils Malt is a flavor that I consider to be rivaled by none. Hops from Hop Head Farms are some of the most aromatic noble hop varieties I've ever seen and in addition to using 100% Hallertauer Mittelfruh in the whirlpool as our only hot side hop addition, we will also utilize a very light dry hop with a noble hop noted for its subtle lemongrass aroma. With the use of very soft water out of our RO system and a gentle boil in our steam heated kettle, I can't wait to put all of the studying in Germany to use again.

Lastly, in addition to all those new beers, we will be moving our 100% Brett beer, which currently has an intense pineapple flavor, into a variety of white wine barrels, new oak barrels, and charred oak barrels where it will sit for a few months before bottling. This month is the stuff of dreams for a brewer wanting to turn the brewery into a playground for beer experiments!

February Beers

After brewing some lagers and Brett beer in December and January, things seemed like they had slowed down for a while at the brewery. Following the release of those beers, I had to get caught back up on brewing our IPA and Imperial Stout again and I felt like I hadn't had anything to blog about in a while. That is all going to change in February. In the coming month we are set up to see some exciting new releases and they will all be coming available in a very brief time span.

First, we wanted to make sure that we had a good lineup for Arizona Beer Week and due to the popularity of our hoppy ales, we decided to add a few more to our lineup. This week will see a new version of a Double IPA, this time brewed with some newly released hop varieties, Denali and Eureka. The new double will be packed with the most intense hop aroma/flavor we can muster. We've got a few tricks up our sleeves to make sure that we can pack even more hop flavor into this recipe than our last double IPA and we will be able to reduce the bitterness even a little bit more. 

In addition to the Double IPA, we will be releasing a second single hop pale ale, this time featuring Cascade hops. However, this is not your average Cascade. Right before I made the move to Tombstone, I had flown out to Oregon to select a lot of Cascade. For those that don't know, what we normally buy as small breweries is blends of varieties grown on different farms. Especially with the popularity of Cascade, any one box of hops may have Cascade grown on 10-15 different farms. While the growers typically say that the hops come from Yakima Valley, that is slightly misleading, since most brokers are blending hops from Yakima, Idaho, Michigan, and New York. While these blends are great for year to year consistency, it kind of sucks to think that great quality, highly aromatic hops from Yakima are being blended with subpar hops from Idaho.

So in September when I flew out to Oregon, my goal was to find the best Cascade I could. In my mind, I imagined the perfect Cascade as having an intense floral aroma and a grapefruit or orange peel aroma to compliment. The floral part being important due to our desire to utilize biotransformation of Geraniol (the hop oil that gives hops a rosy or floral aroma) into Beta-Citronella (which has the aroma and flavor of candied orange peel). Upon making my selection, I was informed by Crosby Farms that the lot I selected was the winner of the 2016 Cascade Cup and it was the first time that a farm from Oregon had won the competition. This specific Cascade lot is considered to be the best Cascade grown in America by a panel of expert judges and I was lucky to be able to get my hands on the last 3 boxes available. 

As if those two beers weren't enough, we will have our first releases from our steadily growing barrel program which will also be our first bottle releases.. Our INTENSELY smoky Strong Scotch Ale aged in Islay Scotch Casks (I hope you love Scotch, because this beer delivers it in bundles) will be available in 500 mL bottles. Following that release, we will have our Imperial Stout aged in Woodford Rye Whiskey barrels, Breckenridge Bourbon Barrels, and a Woodford Bourbon Barrel. The stout barrels have been tasting great and it has been fun to give friends samples to see which barrel they prefer most. I have taken a liking to the Woodford Rye which gives a great vanilla character from the barrel and pairs really well with the rich chocolate character of the base stout. The Bourbon Barrels seem to have taken on more of the character of the liquor itself, likely due to the way the cuts are made at the distilleries as they try to get more of the character of the mash in their bourbon. The bottles of each barrel will certainly make for a good side-by-side tasting and I think we will see that the consensus will be split among the three for which is best.

The last of the barrel aged beers is one that many people might find a little more unique: Berliner Weisse aged in Medium+ Toast White American Oak barrels. The oak character is really coming through well in that beer and is possibly the one that I am most excited about from our barrels so far. That first Berliner Weisse will be a preview of things to come for when we are ready to release fruited Berliner variants that have been aged in the same barrels a few weeks after the first release.

Now that we are back in the groove of brewing ales on a regular basis, stay on the lookout for a lot of exciting new hazy, hoppy ales in the next couple months!
