I exclusively make high gravity beers and I'm low on yeast and and money for a while so I'd like to harvest my yeast cakes and use them in a starter. Perhaps even rinse and split them into empty vials and save for the future. I have a 9%abv red ale fermented with Nottingham and a 7% red ale fermented with s04. Anybody have success harvesting from high abv yeast cakes?
