I've been pretty interested in making my own after enjoying some homebrew the inlaws made. These are also the same folks that got me into making
I missed pics of a few steps; after it was boiled and strained of solids the resultant 4 and a half gallons of beer soup was then cooled with a coil of copper tubing connected to a garden hose. No waters is added to the mix here, just cold water passed the the tubing to bring down the temp. Once it was down to ~75 degrees it was time to pour it into the primary fermenter. That's a fancy name for a 7 gallon bucket with a water trap on top.
