What are the advantages to reusing yeast from a previous batch? I have heard this few times on this board and I'm not sure how it works or why you would do it? To save the few bucks new yeast costs? How do you do it?
I only do 2 ferments then clean the primary. I also do the next batch boil the same day I rack to my secondary.If you did this a ton of times in a row I guess the primary would get kind of gunked up because it would never get cleaned. Other than that I don't think there would be any ill effects.
I love reusing yeast cakes. It's simple and easy and you don't have to worry about making starters.
