I brewed up a batch of Alesmith Wee Heavy, and bottled it at the end of February. It's a really big beer, about 10%, so I've let it sit much longer than I would a normal beer. However, here it is November, and its still not carbonated. I have gently swirled them over the months, but apparently it hasn't helped. My usual problem is over-carbonation, so I'm not really sure what to do at this point. Any suggestions?
