I've never actually bothered to Blog about things befroe, but given the hard work that went into the design of this new web site, I
feel obligated to give it a try.
Last evening, I began what I refer to as my lager ritual, that is, the start of my yeast starter for a lager. Those of you familier with my brewing philosophy know
that I firmly subscribe to the notion of pitching large quantities of yeast, particularly in my lagers. This approach was given a challenge this year as I finally upgraded my boil kettle to
15 gallons and as I result, I typically yield about 11 gal of wort now after the boil. Naturally, this requires more yeast! I've settled into a reasonable process with my "normal strength" lagers
(anything around 1.050 OG) where I start with a 1 liter started on a magnetic stir plate and then pitch it into an additional 3 liter's of wort after 24 hours. After an additional 24 hours, you've
got a pretty good slug of yeast. I then crash the yeast at around 38 °F for 24-48 hours. Some time during that period, I prepare another liter of wort and chill it down to the same
temperature as the starter. The night before brewing, I decant off the liquid in the starter, leaving the yeast cake at the bottom. I then resuspend the yeast in the 1 liter of fresh wort, and
I rase the temperatuer of the fridge to 48 °F (my typical pitching temperature for lagers). I feel this gives the yeast a chance to get used to growing at a coooler temperature before
introducing them to the wort. Bottom line, this yeast preparation method has given me consistantly good results. I typically with drop a 1.050 beer down to 1.016-1.018 (where I typically
start my diacetyl rest) in 7 days.
So there you have it. I'll update the Blog on brew day.
