what temperature will pacman yeast die? I'm brewing some apple cider (1.080sg) with pacman yeast saved from my last batch of beer. its been a bit cold in my house so i put the fermenter in a closet with a small heater on low. worked fine for 4-5 days and this morning i turned the heater up a bit and forgot about it. i came back and the closet was hot and the beer wasn't bubbling anymore. i took the temp with a meat thermometer (not accurate but the only thing Ive got) and it said the beer was just under 100 degrees. the lack of bubbles could mean that the fermentation slowed but i was worried that the yeast will have died. if this is not the case, will this excess heat have any other adverse effects on a cider?
