So I was able to play a bit on Sunday with the Weber 22.5 and as expected, got unexpected results. Note that all of these runs were meatless using Stubbs charcoal. First thing I tried was a full load of coal in one of the holders, probably 20 or so brickettes. This went over 300 F even with the bottom vents closed. Next I tried the minion method, started off fine and stayed around 240 for about 1/2hr and then it started to rise. When I looked inside all of the coals were list so maybe I did something wrong with this one. It started to rain and was getting late so that's all I got to. My next try will be using 6 brickettes and see if I can just feed it. I'm going with 6 as this is how many I had on there lit at the start of the minion method and that was about right for temp. All advise welcome.
