I am weary of doing a big 23# mash in my 10 gallon Gott cooler, so I'm throwing together a short notice mash tun made from a 50L keg. I don't have anything more than a blanket available for insulation. I am wondering if 23# of grain + water will have a decent thermal mass to maintain 152F in a 85F environment without insulation. My LHBS's crush has been giving me consistent conversion after 35-45 minutes, so I don't see me needing to go any longer. Can this big grain bill hold temp for that duration?
