We are considering selling our 2 bulky 10 bbl open top fermentation tanks, and replacing them with with 3 tall and skinny 5-7 bbl conical fermenters. The motivation behind this idea is to do more small batches and better CIP practices, but we are very limited on space. I'm looking for opinions on the tall skinny fermenters. What benefits and negative effects can be expected? I've done some very light google research and read an article suggesting that there is more natural agitation, more rapid fermentation, and less hop aroma volatiles lost in tanks with a higher height to diameter ratio. I've also read that the skinnier tanks are bad for yeast health. Looking for facts backed by science with references, though experience would be appreciated as well.
