I did a California Common, fly sparged, new three tier system using two turkey fryers and a Blichmann Mash tun. Actually, it went fairly well and the beer came out great (the aa of the hops was high, so it was a hoppy steam beer, in a good way. The only major change I have made since is better thermometers and I added insulation for the mash tun. Saving for a 20G Blich boil pot / burner, then my system is ready for easy 10G batches (right now to do 10G I have to get the grains out of my mash tun and boil in that, bit of a pain. I made great beers extract, skipped BIAB (probably a mistake) but I do prefer my AG beers, somehow they seem to have more character to them. More "grainy" maybe?
