I am keeping the open sachet. I am not pouring yeast back into the packet and I immediately seal the packet back up after pitching. It has been a consistent issue regardless of no sachet or not. I'm going to try and find a way to cool the beer during fermentation. Thanks for everyone's help!

For brown ales, I've used Safale S-04 British ale yeast For Light Ales, I've used Safale S-05

I am only putting in about 2-3 grams of the 11.5 gram packet

TLDR - OG to FG fermentation is only taking 2-3 days and has a potentially overripe Banana smell, but no off tastes. Brew day to keg in 6-7 days. Should I be letting the yeast rest longer? Hey everyone, I have made 8 batches of all grain homebrew up to this point, all being 1 gallon brews...
