Homebrewing - Beer, Mead, Wine, Cider

Doing a weekend of brewing. Started it off today making a bourbon mash. I got an ultrasonic cleaner a while back I’ve been itching to use. I’ve seen research papers showing some evidence of it speeding up the aging process and I’ve been dying to try it. Tomorrow I’m doing two experiments, brewing an imperial milk stout and doing a keg fermentation with a jumper to another keg to purge the o2 because I’m a cheap bastard. Never fermenter in a keg so I figure it’ll be a fun thing to try. Lastly, because the yeast was expensive I’m going to try to freeze back some yeast from the starter I overbuilt and use it in another brew down the line.
