After drinking a nice Heater Allen Dunkel a few days ago, I decided my next brew would be a Dunkel. I’ve never brewed a Dunkel as I haven’t done many lagers. I felt like this wouldn’t be too big of a challenge, plus it would give me a chance to experiment a bit. That’s what homebrewing is mostly about. Experiment, change, challenge, explore, etc.
So, I’ve tried the pseudo lager route before using Wyeast 2124-Bohemian Lager, and it didn’t turn out all that wonderful. It was still too warm for the yeast and I got too many sweet esters from it. So, even though Wyeast publishes it as being fine at a warmer temp, I didn’t find that it worked too well.
This time, I’m going the Kolsch route. Per Wyeast “This yeast may also be used to produce quick-conditioning pseudo-lager beers and ferments well at cold 55-60°F (13-16°C) range“. The downside is that I will need to let this set a bit to clear completely. Not a problem.
I found a little 8oz canning jar in my fridge with some Kolsch yeast that I had rinsed and save from March 11, 2012 – Over 7 months ago! It looked perfectly fine, powdery white (unlike some 6 month old S-04 that turned dark). I thought to give this a shot and sure enough, I was able to get a nice starter going with this after about 18 hours. I got a little red neck and made my starter in an old 750ml wine bottle. Worked well! I used the starter after 2.5 days, and to be quite honest, because of the lag time to start, it was still going strong when I pitched it.
