I'm planning on brewing my 2nd AG soon, 5.5 gallons post boil of a big 1.099 OG oatmeal stout with a grain bill of about 19.5 pounds. I'm calc'ing a little of 6 gallons of strike water are required. I've read that my Coleman extreme 52 quart (yes, it's blue) can handle 10 gallon batches, but for much smaller beers, say 1.050. Has anyone here tried to fit 20 lbs + 6 gallons into this cooler?
