I just began harvesting and washing yeast to build up my yeast bank. It has been said that you might not want to harvest yeast from a really big beer.....I'm guessing this is because these yeast are stressed and not as healthy. So, how big is too big?
I have a stout with an OG of 1.080 that I would like to harvest from. I pitched a properly calculated starter on this beer and fermentation has been lovely. Am I ok to save some of this yeast for the bank? How big is too big?
