Since I've got my yeast washing operation down to a science, I was wondering how many generations I should go on a strain. Awhile back, I pitched a new packet of Forbidden Fruit into a wit. I harvested and cleaned it, and ended up with 4 jars in my fridge. I used one of them on a wheat last weekend, and the starter was very active; fermentation of the main wort took maybe 36 hours. I just racked it to my keg, and was wondering if I should bother washing & harvesting the third-gen cake in there. How many generations does it take for mutations to take place typically? Given that I still have 3 jars from the second-gen harvest, it may be overkill (and a waste of time & space) to harvest even more. I mean, the stuff's not gonna last forever, and I don't think I'll be brewing 8 beers for forbidden fruit any time soon.
Thoughts?
