| it fermented a bit warm. Also, when I racked it to the secondary, I probably should have added some priming sugar, to give the yeast something to feed on and avoid it getting oxyginated... |
| Tastes ok. It has a really strong body, and not much hop bitterness. Not my favorite beer, but it does taste good. |
