Fermentation temperature

[Deon Botha]

Is the temperature only important while your yeast is actively working (the first 4 - 7 days) or for the whole first 2 or 3 weeks of primary fermentation? Thank you

I would say far more important during days 1-7 but you don't want to go crazy high, generally, the rest of the time. The question is definitely going to illicit a wide range of responses.

Only the first few days, until activity slows. How much slowing is up for debate. Then you can raise the temperature to help the yeast finish. I do sometimes and not other times. I don't notice much difference but have not compared.

I would stay at the middle of the optimum range of any yeast and not exceed the upper end when warming.
