Fermentation is fermentation. Room temperature is best, regardless of whether it's a primary fermentation or bottle conditioning. The yeast don't know and don't care what it is you're making them do.
im probably overthinking here, but the coopers canadian blonde said to keep fermenter between 21-27c, the fermenter went down to 18, so using heat belt now, and is at 24
but if bottle and just leave in cool dark place the temp would be 18! As it is the same yeast at work I didn’t understand this discrepancy?? May even get below 18 as the weather gets colder in the coming weeks!
Take the heat belt off and leave it at 18, that’s a perfect temperature for good quality beer. The instructions in those kits are usually best ignored.
