I just finished kegging my first attempt at this brew. It has a bit of a banana aroma to it after EOF at 20 days, so I cold crashed it for about 5 days. Then I had to go out of town on business, so I left it on storage mode until day 43. It tastes good and I'm pretty sure the alcohol content is way over 8.5% now, but I like Imperials at like 10% so I don't mind that at all. One thing that did happen is that even though I opened the top and vented it right before kegging, the first keg I filled built up some kind of overpressure and started peeing around the connector at the top, spilling beer in the container external to the bag. I thought maybe I didn't have it threaded right so I was extra careful for the second keg; it started doing the same thing but I stopped it before. I had about 12oz of beer left in the droid which I promptly sampled, of course.
Does this happen or am I somehow missing an O-ring or something between the keg liner and the fill cap? I figured it just was very carbonated (even though it doesn't quite taste like it) and built up a bunch of extra gas that screwed up my kegging process. I tried to vent the second one halfway through but I don't think either keg is completely filled.
I'm about to toss another one and I'll buy some new brewprints and a couple additional keg housings so I can keep my BeerFlo in constant action. Looking forward to trying that out.
