When I have time on the weekend I brew 5 gallons, batch sparging. But usually I don't have time on the weekends because I have a lot of other projects, social engagements et. I would say 4 out of 5 batches are 2.5 gallon biab batches that I do after work on a weekday. I can get home at 5:15 and have a batch in the fermenter by 9:00 and all cleaned up. I don't always need to make a starter for this size, I sometimes pitch a smack pack as is if its fresh into a lower gravity wort.
