Has anyone washed/harvested dry yeast before? I ask because S-04 and S-05 have recently increased in price up to $3.99 at my local store. In an effort to save some cash, I'd like to harvest the S-04 I used for my last batch (re-hydrated and pitched into 1.065 wort). I don't see any issues with this, but wondering if any else does. Thanks!
