I brew 10 gal. batches of beer at a time. Previously I would make two separate yeast starters for the two 5 gal. fermenters. I am interested in purchasing a stir plate and flask. My question is would it be better to make say one liter batch for each fermenter or would I be better off making a two liter batch and the splitting it between the fermenters? Would splitting it at the one liter graduation on the flask be close enough (approximately) for the same amount of yeast cells in each fermenter? I'm sure it would be more difficult getting "half" in each one if I were to decant the excess wort. Any advise would be appreciated. Any recommendations on a good stir plate? Thanks Cowboy up.
