I pitched a 3rd gen 1318 starter into my dipa sat night around 8pm, fermometer read 66-68 deg. By the next morning when I was off to work fermentation had already started with a nice krausen forming. Come home 24hrs later and vigorous bubbling and fermometer reads 72. I immediately started adding shirts that I cut up, wet, freeze for a little then wrap around the carboy. By noon the temp had dropped to 68 with the airlock still bubbling away and after a few hours temp doesn't appear to be rising back up. So did I save this beer from an ester bomb or was the damage already done. It was prob at that peak temp for about 12-16 hrs before I was starting to bring it back down. I'm hoping I saved it and the rest of primary fermentation will clean up any off flavors.
