I tried a finer grind yesterday in an attempt to do better with my OG and I thought I might have a problem with my SS false bottom. The mash looked good but when I opened the valve to start sparging my cooler just laughed at me. Once I got over the horror of it, I went to plan B which involved a collander and alot of wort spilled on the floor. Then to plan C which involved dumping the grain from the cooler into my 32 qt kettle (with bazooka screen installed) with my sparge arm slapped on top. My yield was about a gallon short due to spillage, but the flow out of the bazooka was excellent. It made me think maybe I should either mash out of my kettle, or install a bazooka in my tun. Let me tell you this bazzoka is sweet. Anyone use one of these in their tun? Oh, the OG went great, 44, real close to the 50 target. Thats good for me just starting out.
