I am going to make my first 20 gallon batch of Porter and I am looking for the best way to build up my starter. I typically split batch into 4-5 gallon using different strains and building starters with 4 different strains but this time I want to do one beer of 20 gallons. I have 2 stir plates. Is it best to build 2 starters and put them in a 1 gallon jar and build 2 more? Will the yeast be fine in the jar for 5 days while the other starters are growing? Does anyone have a better method? Any help is much appreciated.
Thanks everyone.
