Hey everyone, I looked around and couldn't find an answer to my question. I know it's fairly common to do 2.5-gallon batches in a 3.5-gallon bucket for primary fermentation, but what about secondary fermentation? I brewed 5 gallons of a brown ale and I want to do a split batch to try a new flavor for my wife and keep the other 2.5 gallons as a brown ale. Is 2.5 gallons in a 3.5-gallon bucket too much headspace for secondary? It's been in a 5-gallon carboy for almost two weeks and I was going to split it up today or tomorrow. I still have 2-3 bubbles every minute or so.
