I've been reading the forums on the subject of starters and the related topic of harvesting yeast for subsequent batches. I understand the issue of not going beyond five or so generations from the fresh yeast. So here's a question. Does anyone ever take the original yeast package, run a starter, immediately divide the result into, say five portions, fridge four and continue ramping the fifth up to pitching density. This way all the samples are only one generation from the original.
