I'm about to give it a shot, I think... I pulled a rookie move and transferred to the keg, then checked gravity afterward. Fermentation didn't finish (come to find out the yeast has a tendency to stall out), so I'm going to add some Safale US-05 to try and get it to finish off. Once it's done (fingers crossed) I'll probably transfer it to a different keg to get it off the yeast. I'm thinking blowoff tube.
