Brother, I've been kegging since I started brewing!
I've only bottled one batch (the stout you had), everything else has been kegged or bottled off the keg. I've been using a one tap converted mini fridge with a black iron pipe draft tower I built since I first started. Got a new (to me) big ass chest freezer a few months ago that I'm slowly building out as a keezer. Got my wood cut for the collar and sanded down, but haven't Waterlox'd it and assembled yet. Pretty excited to go from one tap to four! I only had one ball lock keg for years and then all of a sudden I woke up one day and had three ball locks and about 5 sankes. I'm going to turn at least one sanke into a fermenter. I may end up selling some of the others off to get some cash for other keezer stuff like taps, shanks, manifold, etc.
Your brett IPA I had was one of the best brett IPAs I've ever had. Super fruity, that beer was damn near perfect. I am anxious to compare those batches. The labor day beer I'm brewing will be the first time I've used 644. I know this is the one they initially thought was brett but has been reclassified as a wild sacc? Anything I need to know about 644 before brewing with it? I know I should treat it just like any other sacc yeast, just didn't know of any quirks or oddities I should be aware of. Cheers brother.
