Version 2 India Black Ale Recipe

I took the judges' advice to heart from my entry results in the 7 Bridges/Bison Brewing Pro-Am competition, and with the secondary fermentation now dry-hopping and cold-crashing,  the recipe is below. The main things I have attempted to change in this version are:

1. More hop aroma and more hop bitterness.
2. Less astringency from the dark and chocolate malts.
3. Chewier, richer malt character.
4. HIgher % ABV.
5. Drier finish.

3.0 oz. American Summit Organic Pellet Hops (dry hops)

1 capsule Servomyces (15 mins)

½ tsp. Organic Irish Moss Flakes (15 mins)

5 tsp Gypsum to mash water

1 tsp Burton Salts to Mash Water

White Labs WLP 013 Organic (London Ale) yeast

0.75 cup organic corn sugar for priming

Step by Step all-grain Brewing Instructions:

Make a yeast starter from the White Labs London Ale liquid yeast three days prior to pitching. Cool in refrigerator to separate yeast cake. Pour off most of the liquid.

Cold steep (60º F – 68º F) 1.0 lb Briess Organic Black Malt (500 ºL) and 4.0 oz Weyermann Organic Carafa® 2 (dark chocolate) in ½ water 12 hours (over night). Sparge with 3 pints 170 ºF water.

Steep the crushed grain in 6.0 gallons of water at 153 ºF for 60 minutes. 

Add 1.0 oz. American Bravo Organic Whole Hops to mash in a hop bag.

At 30 minutes steep, add 1/2 of the cold steeped dark adjunct malts to main mash.

At 60 minutes, pour two 1/2 gallon pitchers of wort back over the mash till clear runnings. Sparge with 5.0 gallons of 170º water using rotating sparge arm for 20 minutes.

Place 7 gallons of wort in 8.0  gallon boil kettle including the ½ gallon of cold steeped dark wort and 12 oz of Candi Sugar. Boil for 90 minutes. While boiling, add the hops, Irish moss, and yeast nutrient as per the schedule. 

While boil is going on, reduce third runnings in large pot, bringing 2 gallons down to 1/2 gallon. Add reduction to main boil at last possible moment, when wort boil is complete. Use two smaller pots next time, or a hotter flame.

Cool wort to 68º as quickly as possible using wort chiller. 

Transfer to sanitized 6.5 gallon primary fermenter.  Top off with boiled & cooled water to 5.0 gallons if necessary.

Aerate the wort with oxygen for 50 seconds and pitch the starter yeast. Hold at 68 ºF for 7 days or until fermentation subsides. Use a blow off tube instead of an airlock to avoid a yeast explosion.

When the primary fermentation is complete, rack beer to 5 gallon carboy, avoiding any splashing to prevent aerating the beer. Add the dry hop pellets and keep at 68 ºF for 5 days. Cold crash to 32 ºF over 7 days to settle out hops. Add isinglass finings three days before bottling.

Boil 2 cups water, add 0.75 cups bottling sugar, cool to 68º. Add to bottom of bottling bucket and syphon in beer.

Bottle or keg cold. Note: at 32º, the syphon hose tends to clog with ice. But if you let the beer warm, the hops float to the top.

Allow the beer to carbonate for one week at room temperature, then condition for 2 weeks at 50 - 54 ºF and enjoy your Northern Lights IBA.

The finished volume is: 5.25 gallons

The original gravity is: 1.070

The alcohol is: 9.5%

The color is: 126 HCU (~41 SRM)

The bitterness is: 99 IBU

The final gravity is:  1.012

IBA Explosion!!!

Came up with some special steps in brewing my Northern LIghts Organic India Black Ale, version 2 . . . maybe too special. The original gravity came to 1.070 after a 90 minute boil, with 99 IBU by my calculations using The Beer Recipator. These high gravity results seemed great, until I got home from work this afternoon and discovered the airlock filled with foam and a steady stream of CO2 off-gassing through the top. A small wet spot on the ceiling of my insulated fermentation chamber should have given me a hint that there was pressure building, but I wasn't quite prepared for what was to come moments later.

Airlock atop 6 1/2 gallon carboy moments before  "the event".

I have not seen such a vigorous fermentation so far in my brewing career, so I foolishly thought it would be a good idea to get a clean airlock loaded up with vodka and just replace the one that was having difficulties. With my two children watching from behind me, I pried off the airlock. Bad idea, unless you wrap the whole works with a towel. I got a nasty blast of sour chocolate yeast foam full in the face, in my hair, across my glasses, over my hands, and in a blast radius covering the inside walls and top of the chamber.

The mess was pretty easy to mop up, but my wife says our mud room now smells like, "a dive bar where generations of old drunks have puked up beer and only been partially cleaned up after."

The new airlock filled with foam almost immediately and threatened to blow again. So I yanked it out and draped the opening with plastic wrap while I figured out how to build a blow-off tube and sanitized reservoir from available materials. I feel like I'm reenacting that scene with the mission control engineers from 'Apollo 13', "Houston, we have a problem!"

I cut the hole too big on my first try, but got a snug (and hopefully airtight) seal by slicing through an airlock and  threading through some spare reinforced hose from my sparging setup.

The fermenter's temperature had also reached 73 ºF, so I packed the chamber with ice packs and began to bring things back to a reasonable range.

My handy Erlenmeyer Flask with a Chlorine Bleach solution set up to collect run off from the blow-off tube.

John Palmer suggests you use at lest a 1" diameter blow-off tube to reduce the chance of a clog and further eruptions, but 1/2" is all I have on hand. It now sounds like there is something alive in my fermenting cabinet. A near constant, but thoroughly unpredictable rhythm of boisterous yeast-breathing bubbles.

Judging of My Northern Lights IBA

Back in late April I tried my first crack at creating my own recipe, Northern Lights India Black Ale, and entered it for judging. The bad news is I didn't win the tickets to the Great American Beer Festival in Denver. The good news is, I did pretty good for a first attempt.

The event was this year's organic brewing AHA sanctioned Pro-Am competition sponsored by 7 Bridges Cooperative and Bison Brewing. My final average score was 28, placing the beer into the high end of the Good (21 - 29) category. While there's lots of room for  improvement, 28 out of a possible 50 points is not a bad start. The judges comments have given me some valuable pointers to improving on the recipe. And I have ordered ingredients to try again this weekend on version 2. Only this time the beer will be all-grain instead of partial mash.

Here's the official score sheet key to the Good section:

Good (21 - 29) - A satisfactory beer that generally fits the style parameters. Scores near the upper end of this range may have only a few minor flaws or be slightly out of style and also may be lacking in balance or complexity. Scores near the lower end of this range tend to have more flaws and are likely to have stylistic inconsistencies as well.

Both judges noted sediment around the neck of the bottle, which might have resulted from shipping, but most of their comments match my own thoughts to improve the recipe.

1. The beer got perfect scores on appearance - it is a really black IPA with a good head and wonderful lacing.
2. My hopping did not produce enough aroma, and the bitterness wasn't strong enough to balance the dark grain in the recipe. I have learned from later batches, how to make hoppier beers by using very different approaches to the hop additions and brew times. 
3. I clumsily over-sparged the specialty grains, and also over-oxidized the wort in dumping it into the brew kettle. Until I get two new larger kettles for HLT and lauter tun, I am siphoning my transfers back to the mash tank/brew kettle to prevent oxygenation of the wort.

The next batch will be better (famous last words?), in at least three ways. But all in all, when I count in the fun I had designing and making the beer, and the bounty of having a full five gallons of a good black IPA to savor, I still give it pretty high marks. The recipe can take a few tweaks, and over time I'll become a more accomplished home brewer.
