Description:
First, let’s look at the style. A Kolsch has starting gravity of 1.040 to 1.046, IBUs of 20-30, and SRM of 3.5 to 5. The Zymurgy description of a Kolsch is: Pale gold. Low hop flavor and aroma. Medium bitterness. Light to medium body. Slightly dry, winy palate. Malted wheat okay. Lager or ale yeast or combination of yeasts okay.

Malts can be U.S. or continental, including a fraction of wheat malt if desired. Hopping should be continental noble hops. The yeast is the tricky part, as to my knowledge there is no available Kolsch yeast. The Goose Island Brewery in Chicago brews a Kolsch using a Kolsch yeast from Germany. The Free State Brewery in Lawrence, Kansas, brews a Kolsch using Wyeast “European” ale. This yeast is suggested by Fred Eckhardt. I’ve used the yeast from time to time and think it’s a great yeast, so use this in preference to any generic ale yeast.
Ingredients:

* 6 pounds, U.S. 2–row malt
* 1 pound, Vienna malt
* 1 pound, wheat malt
* 1/4 pound, light crystal malt (10 L.)
* 1 ounce, Hallertauer (2.9% alpha) (60 minute boil)
* 1 ounce, Hallertauer (30 minute boil)
* 1/4 ounce, Tettnanger (3.8% alpha) (15 minute boil)
* 1/4 ounce, Tettnanger (2 minute boil)
* Wyeast European ale yeast

Procedure:
I’m assuming 80% extraction efficiency. The hop schedule broadly follows the German method, and you can substitute Perle or Spalt, and mix and match however you want.

Following Fred Eckhardt’s description of Widmer’s mash sequence, mash in at 122 degrees F and hold for 30 to 45 minutes, and then raise to 158 degrees F for starch conversion. Following conversion, raise to 170 degrees F for mash out and hold for 10 minutes.

Primary fermentation should be done in the mid-60s. This beer benefits from cold-conditioning, so rack to secondary and “lager” at 40 degrees for a couple weeks.

Description:
Here is an extract recipe for a Kolsch brew. I’m real happy with it, and I have several people to thank for this one. Being the dunderhead that I am, I have forgotten some names (most notably the fine brewer up in Alaska who assisted with my Kolsch yeast questions). It is based on the recipe found in Papazian’s “The Complete Hombrewer’s Companion” (I think that’s the title), except for different malt counts and yeast and fermentation.
Ingredients:

* 6.00 lb. Light Dry Malt Extract
* 0.25 lb.lb. Wheat
* 0.50 oz. G. Northern-Br. 6.9% 75 min
* 0.75 oz. American Spalt 4.0% 15 min
* 1.25 oz. G. Hallertau 3.1% 15 min
* 0.50 oz. Czek Saaz 3.5% dry hopped
* 0.50 oz. G. Hallertau 3.1% dry hopped
* 1 teaspoon of Irish Moss
* Kolsch Wyeast

Procedure:
The .25lb. crushed wheat grain was placed in a grain bag, put in the cold water (2.5 gallons), and raised to 165 degrees where it steeped for 10 minutes. I then raised the it to a boil, added the boiling hops (the Northern) and the DME. After 60 minutes I added the flavor hops (.75 oz. of the spalt and 1.25 oz. of the Hallertau) and 1 teaspoon of Irish Moss. I then let this boil for 15 minutes (75 minutes total).

I then put in my primary and added the Kolsch Wyeast (liquid, natch). This is an interesting yeast. I let it ferment at around 62-64 for about 1 1/2 weeks, until it seemed just about done. I then threw it into the fridge at 42 degrees for about 2 weeks. When I took it out, the yeast appeared upset by the sudden temperature change and it fermented rather energetically for about 1/2 day or so, and then it slowed down. I toook a specific gravity and it was 1.08. Done. (I screwed up the starting gravity. Ooops).

I primed and bottled. Let it sit for two weeks, then placed it in the fridge. Let it sit in teh fridge about 1 week before drinking, and MMMMMMMMMMMM…..good stuff.
