Gary Johnson’s Og’s Grogg Brewtree

This current brewtree evolved from a portable unit.  I designed it to be gravity fed from hot liquor tank (HLT) to fermenter. I designed the parts and a friend fabbed them up. The first feature is the modularity to move the jet burner from any vessel while lit (with a gloved hand). It also has a hopback, water filter, oxygenator and reverse chiller — all home-built. The latest addition is a Recirculating Infusion Mash System (RIMS) / pump system with the heat exchanger in the HLT. This has served me well, but I am in the process of designing and building a Brutus 10 (single tier, stainless 10-gallon brewery) so I can do more, with less hassle on brew day, out of my garage. (Winters in Pittsburgh really suck.)
