Hi all, been brewing for just about 6 years now. Started with extract on the stove like 99% of us. Was pretty quickly kicked out of the kitchen to a propane burner in the garage. Realized that brewing in January in Northern IL is not so much fun. Spent the next year building an all electric brewery in my basement and haven't looked back since. Found this site due to the yeast starter calculator. Planning a Czech Pils tomorrow and I am doing an experiment with old saved yeast vs. new yeast. Using 2124 for an 11g batch split in half. 5.5g gets the new yeast, 5.5g gets the old yeast. Both have been grown to proper pitch rates and have had cell counts done. I performed the counts and came up well above expected according to yeastcal.com. The Bruakaiser method was right on with my cell count.
