I do this all the time with my bottle harvested yeast. Make a big starter, then pour some off in to a mason jar at high krausen. I'll use this for my next starter and step it up till I have enough to pitch. I'll then wash the yeast cake from each batch into 3 or 4 pint jars,step those up, and have enough for 8 more batches. I'll wash each of those cakes, and put each one into one large quart mason and have a pitchable amount in each of the 8 jars. After that I'll start over again with a fresh harvest.
