Happy to report the fermentation seems to be going well. But I have found out late about the importance of temperature control during fermentation.
I've used US-Safale 05 Yeast which has 18-26°C (64.4-78.8°F). range.
I don't have cooler or any other setup yet, I just put the beer in cooler place in the house.
The ambient temperature in that place was likely:
Day 1: 65f
Day 2: 70F - really active fermentation with visible activity and thick foam on top
Day 3: 75F
Day 4: 80F - Beer was already slowing down fermenting, the foam layer on top reduced a lot
Day 5: 80F - Foam layer was nearly gone with islands of foam floating on top
So actual wort was probably a bit hotter.
At the end of Day 5, I've found out that even a few degrees above recommended high range can give off-flavors, even though my yeast type is more forgiving.
I've put the ice bottles/arranged some cooling for day 6, But it will be some hassle to keep this up each day. The weather will be hot for a week and probably get cooler later.
So my question would be if there is damage is it already done or does it make sense to keep the beer cool for the following weeks?
And the second question would be I've found Kveik is a good option for hot weather? Is it something I should switch to before I find some sort of temperature control solution?
