just read the instructions....
" 1. Place 1-1 ½ gallons water in the brewpot, and bring to a boil.
1. Turn the heat off. Place the both grains in the steeping bag, and steep in the hot water for 20-30 minutes. Then remove and discard the spent grains, and heat the water again to near boiling."
The directions are written poorly, and lack to tell you what temp to steep at, you don't want to steep too hot.
