This is a clone of less well known Gordon Biersch Dunkles. This extract version is for those of you who don’t have the equipment for an all grain homebrew setup.
If you are an all grain brewer, here is the all-grain version of the Dunkles that I cloned.
You can use any clean lager yeast, but Gordon Biersch uses Weihenstephaner 34/70 lager yeast. It is available dry from DCL/Fermentis as W-34/70. If you can’t find that, you can use the SafLager S-23.
This beer is normally served unfiltered. You could filter it of course, but you would lose some of the character.
If you don’t have a temperature controlled refrigerator, you will have a very hard time making a good lager. Unless, of course, you have a cave.
A diacetyl rest is very important and when your rest is done, slowly drop the temperature.
You should lager the beer for at least four weeks.
