Had an interesting revelation this last week, and wanted to share with you all...
i'm doing 1.5 Gallon BIABs and after looking jealously at all of the nifty pictures of people's cooler mash tun conversions... i thought... instead of struggling with keeping my temps up, and messing with my mash on the stovetop, why not use a cooler?
So, my idea, that worked flawlessly, to share with you all.
my brew kettle fits inside my coleman cooler. so, i placed a bath towel in the bottom of the cooler, then poured 3 gallons of 170* water into the cooler, then placed my kettle in it after doughing in my grains.
the result? a 90 minute mash of an AG wheat that stayed 154* the entire time. hit my gravity nearly exactly.
here's a few pics.
the brew kettle in the cooler, sparging, the boil, and RDWHAHB.
