So my first AG brew day went horribly wrong. I had a converted keggle for a HLT and brew kettle and a converted 10 gal round rubbermaid for my mash tun with a braid ring from palmers book. First the braided ring collapsed on me and it was just trickling out after mashing, I ended up dumping it into another cooler I had laying around with a plastic false bottom. I was planning a 11 gallon batch pale ale, used about 20 lbs of grain, and got less than 5 gallons out of it. I'm not sure how it will turn out... Anyway, i put about 15gallon of water into it, how come I got so little? was it all stuck in the grain? I've since killed the idea of the braid and got a kettle screen for my next batch. Any ideas?
