Does anybody do this? It seems much easier and more sanitary to harvest yeast from a starter vs. washing. My idea is to step up a WL vial to 1L and then 2L. I should end up with roughly 400 billion cells using a stir plate. I then would crash the starter and pour the yeast slurry into 4 sanitized WL vials. Each vial would contain roughly the same amount of yeast as a new vial. Refrigerate and use as needed. Any problems?
