No, I want to buy ingredients for 5 gallons, then split it in half. I want to brew a half batch (2.5 gallons) one day, then brew the second half another day with the same process, only pitching a different yeast strain. Ideally, it would be nice to brew the whole batch, then split in two different fermenters with two different yeasts. Right now, I can't do that because I have a small kettle and one 3 gallon carboy.
