First all grain batch today using my new converted 54Qt Coleman cooler. Its red, so I know its not quite up to par, but free is better than blue. Its a very sessionable ordinary Bitter, 1.035 Original Gravity Hopped strictly with EKG, my efficiency was only 70% but I'm not too worried given its my first all-grain batch. Looks like it should be done and ready for drinking within the month!
