I left for the lake for a couple days my ice bath fermentation cooler inevitably ran out of ice and spiked to 75 from 67 for about 17 hours during primary fermentation. This is a oatmeal chocolate stout using nottingham. I just started cooling it back down primary seems to almost be over. Are off flavors usually easily noticeable in stouts? Are we talking major esters here? Should I dump this?
