I have been brewing ales for years, but this is only my second attempt at a lager. I am doing a Kolsch, following a recipe from my local HBS. The recipe states to start in a primary at 68-ish degrees for 5-7 days, then rack into a secondary, cool to 50-55 degrees, and lager for 2-3 weeks before bottling.
I have a few questions:
1. I get the nagging sense that I should actually have the primary at a colder temperature range when I lager. Is this true, or I am doing right with the written recipe? I *do* know that if I primary ferment at a colder temp, I am supposed to raise the temperature of the primary up before racking to decrease the diacetyls.
2. When conditioning in bottles (for a lager yeast), should this be done at room temp or lagering (cold) temp?
