New brewer here and my question is along the same lines. Brewing a brewers best kit now. Whiskey barrel stout. It smells great and I can t wait to try it. But I wasn't able to keep the temps down within the recommended range. It's rang e was 60-70 deg and when I checked it, it was running a t about 70-72. It fermented for 3 weeks before I bottled it. The OG was at 64 and the FG was at 21. It went to 21 within 4 days then stayed there. I just bottled after adding priming sugar to the the bottling bucket.
It tasted great before I bottled so I'm happy with the flavor overall. Only difference I see is the ABV is a little low and it's a little thicker than intended.
My question is really about the temp. What does a difference in temp make to the final taste. Leaving out extremes, how does the same beer brewed in the same way except say, 5-8 deg difference in fermenting temp taste different? Can that be classified or described?
Thanks,
Steve
