First off, I'll just say I'm just venting on this one. I'm choosing to believe this was just an isolated incident until proven otherwise.
Brewed an old ale in mid september. Fermented for a month, final gravity was steady, and just under target (1.021 vs 1.023). Bottled mid october and then three weeks later, gave the first one a try. Carbonation was on the light side, and obviously very young. When cold, you got very little aroma. Once it warmed up to where it had a nice aroma, the alcohol came through a bit too much. But anyways, no worries, its young and needs a good bit of aging.
Opened another right after thanksgiving, so another 3 weeks in the bottle (6 total) to check on progress. Aroma definitely better, alcohol presence mellowing.... definitely making progress. Still low on carbonation, but not badly so.
Opened on tonight.... and 5 minutes later was able to pour it in a glass. This was my first uber-gusher.
Anyways, I'm just gonna chalk it up to a bottle with a little something funky in it that just kept working. I have a hard time thinking that a beer that was just getting close to properly carbed at 6 weeks then proceeded to go well past carbed and into beercano land in the following 3 weeks. Oh well, only time will tell.
That is all, story-time over.
