The Results

While there are some recipe changes in store for the next iteration, this beer primarily misses the mark on technical merits. Most noticeably my beer has a touch of honeyed oxidized malt character with perhaps a faint hint of diacetyl that is not present in the commercial beer.

I am typically very careful to limit O2 exposure, especially in fermented beer. In some ways, the oxidation of this beer is welcome as it is making me look critically at my process and think of ways I can limit O2 pickup. The biggest risk for oxidation in my process comes at two locations: the cold crash and packaging.

When I cold crash my beer, there is usually some suck-back of air into the fermenter due to a vacuum being pulled as the liquid’s volume decreases as it cools. I typically put a little CO2 head pressure on my beers as I cold crash in order to prevent this. With this beer, I got lazy and skipped this step. Nevermore!

The second biggest opportunity for O2 pickup is when I rack finished beer to my keg. I always purge the keg, but perhaps I am not always as careful as I should be in gently racking the beer and purging the racking cane or fermenter head space once it is opened up. In a perfect world, I would be doing a completely closed transfer — this is something I’m looking into and hope to implement in the future.

In terms of recipe, I believe the malt bill I am using is nearly perfect. There is a slight color difference between my beer and the commercial example, but I believe this has more to do with some yeast being suspended in the homebrew, and not a dramatic miss with the malt bill. I may bump up the crystal malt ever so slightly in the next round — perhaps only by a couple ounces.

The biggest recipe difference that I need to implement for the next round is in regard to flavor and aroma hops. The commercial beer has a substantial grapefruit pith and slightly spicy / herbal hop character. While this character is present in the homebrew, it is not nearly as intense. The homebrew’s bitterness level is spot on, but the aroma and flavor needs to be dramatically increased. For the next iteration of my recipe, I intend to boost the amount of late hopping at least by an order of 2 or 3 in order to get closer to the commercial beer.

Circa ’96 Redux IPA – Homebrew Recipe & Review

ipaThe new proprietary hops currently being developed by the likes of HBC and others in the Yakima valley are wonderful, interesting varieties. Citra, Amarillo, Mosaic, Nelson, and Galaxy with their intense flavors of tropical fruits and citrus are both novel and delicious. They’re also, very much in demand by today’s craft brewers. Over the past couple of years I’ve been playing around with the idea of someday, in the not-too-distant future starting a craft brewery. With the competition  for these hops coming from established brewers with deep pockets, it can be be very difficult for a new brewery to establish contracts for these new varieties. With this reality in mind, it would be an interesting proposition to see if there is a combination of readily available hops (like those popular in 1996) coupled with contemporary techniques (dryness, massive whirlpool, massive dry hop) that can be utilized to create the bright juicy hop character seen in today’s most popular IPAs. This is my first attempt at a recipe that strives to do just that.

Tasting Notes:

Judged as a BJCP 14B. American IPA

Aroma (5/12):
There is a substantial hop fruitiness that is almost lemony on the nose. The upfront fruitiness is supported by some pine and an earthy, almost musty hop character with spicy undertones. Some grassy dry hops notes are present. The malt is very neutral. In general the hop character on the nose is very muddled.

Appearance (3/3):
The beer is deep gold, almost copper, and surprisingly clear. This is astonishing considering that the beer is bottle conditioned and dry hopped. A nice tight white head persists.

Flavor (8/20):
The hops are upfront and dominated by a lemony citrus quality muddled by some resinous notes of pine and spice. The bitterness is quite sharp and coarse. The malt present is slightly toasty and dry. There is some boozy alcohol on the finish as well as a touch of honey-like oxidation.

Mouthfeel (3/5):
Medium-low bodied with a prickly effervescence. A bit over-carbonated. The hop bitterness borders on astringent.

Overall Impression (4/10):
This beer is a long way from being a great. In particular, I think the hops choices are somewhat poor, creating a muddled and at times conflicting hop character. In the next iteration, I plan to use fewer varieties that are more synergistic than the combination of citrus and pine that I employed in this recipe. The malt character is great — lean and dry — right where I like my IPAs to be. I made the mistake of bottle conditioning this beer which seems to have imparted some oxidization, making it tough to truly judge the merits of this recipe.

Good (23/50)

Cloning Sierra Nevada Pale Ale

Somehow, I’ve managed to never make a true attempt at cloning a commercial beer. This is somewhat regrettable as attempting to reproduce a reliably consistent commercial product is an opportunity to not only test your process controls, but also gain a true understanding of how certain ingredients and techniques can impact a final beer. Personally, no beer would be better for a clone attempt than Sierra Nevada Pale Ale. Not only is this a beer that was very formative in my journey towards craft beer, it is also reliably available, fresh, and consistent.

The first step is researching the beer you’re trying to clone and establishing a set of specifications for that beer. In the case of Sierra Nevada Pale, their website provides a good starting point in terms of gravities, bitterness, and base ingredients. From there, a number of other websites and forums provide additional anecdotal stories and recipes that can inform your own formulation. With the research complete, I formulated the following recipe.

The Results

An important part of the cloning process is a critical review that involves consuming the beer side-by-side with the original, preferably blindly. This allows you to note critical differences which can be projected out to future recipe iterations. Unfortunately, my first attempt clearly did not result in a clone. This however is not a failure, as it allows me to make process and recipe changes to hopefully create a clone in future iterations. Below I’ve outlined the critical differences between my beer, and commercially available Sierra Nevada Pale Ale and the changes I plan to incorporate into the next version of the beer.

Aroma:

  • The homebrew version of the beer has far more yeast character than the commercial beer. Specifically, my beer has a distinct floral and fruity ester (pear and berry) not present in the commercial beer. In future iterations, I plan to pitch a larger starter and provide additional oxidation of the wort to discourage the production of yeast esters.
  • The commercial beer has a brighter grapefruit pith and slightly herbal hop aroma. I plan to dramatically increase the whirlpool addition of cascade hops in my beer.
  • The homebrewed beer has a distinct dark fruit, dark caramel malt aroma. My original intention was to stick with American crystal malts, but was forced to substitute out British crystal malts due to availability. This had a huge impact on the final beer. I will stick to American maltsters in the next iteration.

SN Pale Ale CloneAppearance

  • My beer appears a shade darker than the commercial beer. My beer has better head retention than the commercial beer. In the next recipe iteration, I will dial back the amount of crystal malt to lighten up the beer color.

Flavor

  • Again, my beer has a much richer, darker crystal malt character. This is the by-product of using British crystal malt. The choice of crystal malt made an enormous difference in the final beer. For the next version, I will stick to American maltsters.
  • My homebrewed version is lacking in the fresh cascade hop grapefruit pith flavor. I will dramatically increase the Cascade whirlpool addition in the next iteration of this recipe.
  • My homebrew is sweeter than the commercial version. The commercial beer attenuates to approximately 79% apparent attenuation. My version only attenuated to 75%. I will mash lower for the next version of the recipe to attempt to further dry out the beer.
  • Sierra Nevada Pale Ale has a slightly grainy / tannic finish. This is likely a byproduct of high levels of sugar extraction. I will attempt to boost my extract efficiency for the next version of the beer.
  • My homebrew is less bitter than the commercial version. Increasing my whirlpool additions should bring the beer closer in line with the commercial version.

Brambic – Spontaneously Fermented Wild Homebrew

Against what may or may not be good logic, I’ve begun a new sour beer project. My goal is to successfully create a delicious sour beer fermented only from airborne yeast and bacteria. There is something beautiful about the idea of successfully producing a delicious sour beer that reflects the micro-flora present where I live. I love the tangible connection that can be made with world-renowned Lambic brewers who continue to brew traditional spontaneously fermented beers (as well as American craft brewers like Allagash, Jester King, and Russian River). I am keeping this project as wild as possible; I will not be culturing yeast from fruit, grains, bottle dregs, or any other source, rather only what I can capture across the cool evening breeze.

Brooklyn wild cultures.

Brooklyn wild. What fermentive creatures lurk in our Gowanus air?

The Internet is full of stories both of success and failure when it comes to truly spontaneous beer. Whenever I attempt a technique that includes a high probability for failure, I try to set as many variables in my favor as possible to get a successful end result. There are no guarantees for success in a project like this, but taking a few simple measures can greatly increase your odds. Using this logic, I decided that running multiple samples and testing their qualities before pitching into a full 2.75 gallon batch of beer was the way to go. This was especially important given the fact that I live an dense urban environment with little vegetation and no fruit bearing trees that could be attractive homes for wild yeast.

My Process

_DSC1962Initially I prepared (3) 8 oz. samples of sanitary 1.030 OG wort and placed them boiling hot into pint sized mason jars. I added 0.3 ml of 88% lactic acid to each sample in order to acidify each below pH 4.5. My goal is to inhibit pathogens from growing in the wort as well as non-pathogenic bacteria that can produce objectionable flavors. Since I would be tasting the wort, I wanted to minimize terrible tasting samples as well as ones that could potentially make me sick.

Each of the three samples were placed around my apartment. One was located on the roof of my building, one in front of an open window at the rear of my apartment, and one in front of an open window at the front of my apartment. Each were covered with a couple layers of cheese cloth to prevent any insects from entering the sample and then left to cool for approximately 24-hours. After 24-hours I fitted each jar with a lid and airlock to create an anaerobic environment, providing control of another variable and putting selective pressure on the organisms growing in the wort.

I completed this experiment in the late fall, which according to American Sour Beers offers the best probability for culturing yeast and bacteria that will have a positive fermentation character.

After approximately one-month, I completed a sensory analysis of each sample (smell and taste). In hindsight, I should have also taken pH and gravity measurements.

_DSC2024Sample A – In Front of Window – Small filmy pellicle. Cabbage, some baby diaper. No apparent alcohol flavor.

Sample B – Outside on Roof – Small filmy pellicle. A couple spots of white fluffy mold. Some alcohol on nose. Light rubbery phenol.

Sample C – In Front of Window – Small filmy pellicle. Cabbage. Some oniony aromas. Pretty sweet, low alcohol.

Encouraged by the initial results, I stepped each into a three new 300-ml sanitary starters. Each were allowed to ferment for another month under airlock.

Sample A – Very sweet. Didn’t appear to ferment much. Clean.

Sample B – Quite sour. Some definite plastic-like phenolics and slight alcohol. Some pleasing barnyard notes.

Sample C – Reminiscent of pickle juice. The most sour. Definite alcohol on nose. Not very pleasant.

After the second round of fermentation, I decided that Sample B (the sample pulled from my roof) was the most pleasing (or least offensive). I pitched it into a fresh 1200 ml starter (also under airlock) and made preparation to brew a full 2.75 gallon batch. For my recipe, I decided on a simple golden grain bill to act as a clean slate for the culture to express itself.

Parabola Clone Review

Over a year ago, I took a shot at brewing a clone of Firestone Walker’s Parabola. According to Firestone Walker, Parabola is characterized by:

Bold bourbon, tobacco and espresso aromas and a hint of American oak greet the nose. Rich, chewy roasted malts, charred oak and bourbon-like vanilla fill the palate and create a seamless finish.

The recipe was derived from a combination of information compiled from Firestone Walker’s website, and my own tasting notes. Unfortunately, my beer missed the spec pretty badly in terms of fermentability. That said, it is still a pretty nice beer.

Tasting Notes:

Judged as a BJCP Category 22C. Wood Aged Beer.

Half of the batch was aged with Larceny (wheated bourbon) soaked oak. Half of the batch was aged with Rittenhouse Rye soaked oak.

Half of the batch was aged with Larceny (wheated bourbon) soaked oak with the rest aged on Rittenhouse Rye soaked oak. The overall differences between the two batches were extremely subtle with the Larceny exhibiting slightly more caramelly notes, and the Rye version showcasing a subtle background spicy note.

Aroma (8/12):
Initially there is a impression of sweet vanilla oakiness. Additionally there is a mellow roasty character with notes of bittersweet cocoa  and a slight hint of coffee. Roasty impression increases as the beer warms in the glass. Under the roast is a caramelly toffee malt character. A slight hint of oxidized malt (dried cherry, fig) gives a hint to the beer’s age. Below the vanilla oakiness is an aroma of raw sawdust that hints at the oak cubes which were used. Some warm alcohol is apparent.

Appearance (3/3):
Jet black with a low tan head consisting of tight bubbles that persist. Beer pours with a readily apparent viscosity.

Flavor (10/20):
Flavors are round and fill the mouth with intensity. Heavy amounts of roasted coffee are apparent as is a substantial amount of chocolatey roast malt. Creamy and smooth with only a hint of hot alcohol. Bitterness is high but balanced against a high level of residual sweetness. There are some pleasant burnt sugar toffee flavors on the finish. A bit too sweet and filling to be drinkable in any quantity more than 8-10 ounces.

Mouthfeel (2/5):
This is a huge beer with a luscious mouth-coating viscosity. Carbonation is medium. Roast character is slightly astringent.

Overall Impression (5/10):
This is a massive beer that falls short in terms of balance compared to its inspiration, Parabola. The bourbon and oak character in Parabola is much more integrated and rich, whereas the oak in this beer comes off a bit artificial tasting. This beer is like a  big, rich chocolate milkshake – luscious, but only consumable in restrained quantities. Additional attenuation would be a welcome addition to this beer.

(28/50) – Good
