I had a heater near my BIPA the night after I brewed it to keep it above 70 and when I checked it yesterday morning it was fermenting like crazy and the temp was off the chart of my thermo strip. I put the heater on fan, and wrapped it with a cool wet towel. This morning it was at 72. I rewetted (if that's the word) the towel and left the fan on. Im sure itll drop more. My question is, at what stage of fermentation do off flavors arrive most from off temps, and am I gonna have an ester batch from probably 12 hours of active fermentation above 75? Thanks for any any advice.
