Title: Counting Yeast Generations
Post by: arboyd72 on September 05, 2010, 04:10:44 PM
Within the last 6 months I have started re-using my yeast.  I will make a starter then before pitching I pour off a portion and store until my next starter is made.  Since I am really going for yeast growth, would I still count the generations everytime I make a starter (as I would if re-using a yeast cake)?

I think the consensus a few months ago on the subject was - each starter is ground zero. Pitching on the cake, or washing the yeast is where your gen. count increments....

I usually make a starter from a fresh culture, use it in a beer that does not exceed 1.060 and after fermentation, pour what's left of the slurry after racking to a keg into a sanitized 2 liter soda bottle that's labeled with the yeast strain and the date. When the yeast settles there's a nice layer of beer with alcohol that goes into the fridge. I use a little of the contents to make new starters and it usually lasts me up to a year with making starters with it. I call this my "mother-ship program".
