I’d like to take a 5 gallon beer kit from NB and break it down into 5 1 gallon batches to experiment with. My plan is to do the initial recipe as normal, up to primary fermentation. Once I’m ready to put it in the fermenter, I want to break it into 5 2 gallon containers, with 1 gallon in each. Then, add additional ingredients (fruit or fruit extract, etc), to experiment with different flavors.
My question is, how do I break up the yeast from the kit for the 5 separate containers? One suggestion from a friend is to start the packet of yeast a couple days before brew day in a wine bottle. Add some malt extract, pitch the yeast, and let it go. On brew day, once I’ve got the must in the 2 gallon fermenters, divide the started yeast into 5 parts and pitch it.
Will this plan work, or am I doomed to failure? Any thoughts on how much malt extract to add? Any other ideas on how to do this?
