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.
