Brewed a Northern Brown extract kit on Saturday, hit the target OG. Pitched yeast a little cold (63F), but activity was in full swing by yesterday morning. Woke up this morning (Monday) to find that there was beer pushed out the top of the airlock - not a full on gusher, but significant.
The top of the fermentation bucket was bowed, so I cracked the lid a little to alleviate the pressure. Is there anything else I should do besides re-sanitize the airlock and replace on top the fermenting bucket?
