Is it possible for a beer to carbonate while in a secondary? Mine appears to have.
Here's the situation... I recently brewed a 1.080 Belgian Ale and fermented it in a 6.5 gallon glass carboy. After 3 1/2 weeks, the gravity dropped to 1.019, so I transferred it to a 5 gallon carboy. I made enough to completely top off the carboy, so there was only about 1/4 inch of space between the beer and the stopper. It's now been 6 weeks and it's always been continuously bubbling in the secondary (once every 12-15 seconds). I checked the gravity today and it's down to 1.012. It seems to be pretty well carbonated. Do you think this was because of a near total lack of oxygen? Should I prime as usual when bottling?
Many thanks, guys!
