I'm going to try a new to me dry hopping process that a user on reddit swears by. I brew small 2 gallon batches and I own a few 1.5 and 2.5 gallon Torpedo kegs. I ferment in a 3 gallon Fermonster with a modified lid to do oxygen free transfers. My plan outlined in this user's post is to let the beer totally ferment out and crash it.
Then transfer to a purged keg already loaded with hops. This keg is outfitted with a Flotit 2.0 floating dip tube. Keep the keg in the high 40's, low 50's and invert the keg every 12 hours for 36 hours. Crash it, then transfer to a serving keg.
Here is the
thread I'm talking about.
