Brambic – Spontaneously Fermented Wild Homebrew

Posted on May 2, 2015 by Nick Ladd

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. 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

Initially 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.

Sample 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

Posted on April 20, 2015 by Nick Ladd

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

2014 Gueuze Brewday

Posted on April 6, 2015 by Nick Ladd

Gueuze is a wonderfully complex sour beer that is typically a blend of 1, 2, and 3 year old spontaneously fermented Lambic batches. While, technically not a Lambic (Lambic is a protected term for a specific type of beer brewed within a specific geographic region of Belgium), this beer is made in the spirit of Lambic. It eschews the typical spontaneous cultures used in traditional Lambic fermentation for a commercial microbe blend (Wyeast Roeselare) combined with grown up bottle cultures.This batch of homebrew marks the my second annual batch of Lambic-style beer that will ultimately become part of a 3-component Gueuze blend that includes 3-year, 2-year, and 1-year old Lambic-style brews.

To further provide variation (and flexibility) in what will ultimately build the blend, I brewed a 3-gallon batch the was split three-ways and inoculated with distinct culture grown up from various bottle dregs: Jolly Pumpkin La Roja, Russian River Framboise for a Cure, and my house bug culture.

Honey | Orange Pale Ale – Recipe and Review

Posted on March 22, 2015 by Nick Ladd

Synergy between ingredients is something that I often seek out when writing a new beer recipe. In this particular case, I started with the premise of wanting to use orange blossom honey in a beer. Orange blossom honey has a delicate orange flavor as well a soft floral honey bouquet. Building a beer recipe around these attributes, I started with a Belgian Pilsner malt base which I’ve found to produce a honey like sweetness in my beers. From there, the base malt was accented with a small amount of Gambrinus honey malt to emphasize the honey character. Additionally, I delicately hopped the beer with Mandarian Bavaria hops which I’ve found to have a pronounced sweet orange (not pith) character that would be delicate enough not to overpower the honey.

Aroma (10/12):
Low to moderate floral honey notes. There is a medium to medium-high sweet citrus / orange / tangerine hop aroma. Some soft candy-like malt sweetness is in the background. No alcohol, DMS, or diacetyl. The is a touch of grassy hops in the background.

Appearance (2/3):
Color falls somewhere between a light copper and a deep blond. There is a slight haze to the beer. Fluffy white persistent head.

Flavor (17/20):
Moderately high hop flavor that is like sweet or candied orange. None of the pithy bitter citrus flavors that are often associated with traditional types of citrus hops. Honey is strongly present and quite floral. Malt is soft and bready with a light crackery character. The hop bitterness is medium-low and leaves behind just a hint of malt sweetness. There is a wonderful honey flavor that persists through the finish.

Mouthfeel (3/5):
Crisp with a medium to medium-low body. Quite balanced. No astringency. Beer has a medium-high carbonation which is slightly biting.

Overall Impression (8/10):
This is a very nice balanced pale ale that showcases the honey content. The beer is exceptionally balanced with layer of flavors; none of which stick out or feel out of place. Very well crafted beer.

Excellent (40/50)

Triple IPA Brewday & Review

Posted on January 8, 2015 by Nick Ladd

Take a ridiculously hoppy double IPA, increase the hopping and alcohol to ludicrous levels, and you have a decent outline for crafting a triple IPA. These are fun beers to brew, and a great way to use up any extraneously hops that may be buried in your freezer. This beer is very much in the same spirit as coveted beers like Pliny the Younger (you can read more about my club’s attempt at cloning the Younger, here).

This is a tough beer to brew as it can easily fall victim to common faults. The most frequent and egregious fault with American-style IPAs is not achieving adequate levels of attenuation. Nothing ruins a big hoppy beer’s drinkability quicker than excessive residual gravity or caramel flavors. This is even more apparent when you’re pushing the beer to triple IPA levels. Controlling fermentability with the addition of simple sugars and low mash temps will take you most of the way. From there, it is key to pitch a big healthy population of yeast, adequately oxygenate the wort, and carefully control fermentation to keep higher alcohols in check.

The second most common fault would likely be harsh or grassy hop flavors. This most commonly occurs when brewers leave dryhops in contact with the beer for excessive periods. Many sources cite the fact that the majority of hop oils are extracted within the first 24-48 hours of contact with our beer. Anecdotally, I’ve definitely experienced this and typically now only leave dry hops in contact with my beers for 2-3 days, maximum.

Lastly, it is extremely important to limit oxygen pickup post fermentation with your hoppy beers. Hop compounds are extremely susceptible to oxidation. Very few factors will contribute to the destruction of a hoppy beer quicker than oxygen. Purging vessels, pushing beer with C02 in closed loops, and cold storage can greatly increase the shelf-life of your hoppy beers.

Tasting Notes:

Judged as a BJCP Category 23 Specialty Beer

Aroma (10/12):
Huge, punchy hop-nose. The hops are extremely juicy and tropical — reminiscent of mango, orange, and pineapple. In many ways, this beer reminds me P.O.G. (passion fruit, orange, guave) juice. There is a moderate amount of grassy, plant-like aromas. By and large the hops are almost uniformly fruity with very little pine or resinous aromas. Malt character is slightly bready. No alcohol, DMS, or diacetyl are perceptible.

Appearance (1/3):
Beer pours a muddy copper color. Extremely hazy with hop compounds. Beer is capped with a bright white, thick, persistent head.

Flavor (10/20):
Taking a swig from the tasting glass fills your mouth with huge, round, hop flavors. The flavors are very fruity and tropical, although there is a slightly biting, resinous, bitterness on the finish. There is a bit of residual sweetness that keeps the beer feeling slightly full and heavier than I would like. As the beer warms, some warming alcohol dances across the palate.

Mouthfeel (3/5):
Medium body and carbonation. Some light hop astringency is present on the finish and detracts from the overall drinking experience. The hops seem to lend a creamy texture to the mouthfeel.

Overall Impression (6/10):
This beer pushes the level of hoppiness that I am able to enjoy almost to the breaking point. The beer is young and brash with bold assertive flavors that come off a touch green. It is very much in the same vein as beers like Pliny the Younger, which are best enjoyed in small glasses and shared with friends.

Very Good (31/50)
