After of year of extract brews, tomorrow is my first all grain day. I have everything lined up in my brewery,...errr. garage, and a yeast starter whirling away on the kitchen cupboard. I have seven gallons of water in my electric HLT, ready to plug in the morning, but while I was rehearsing steps in my mind, I thought of a question. Ambient in my brewery is 55 to 60 degrees these days. The HLT will heat the water to 168deg. F., If I prewarm the igloo mash tun with water from my domestic hot water system, 130 deg. will I end up overshooting the mash temps, assuming the 10 lbs of grains are at room temp ? I am trying to learn Brewsmith 2, while I do this, and I couldn't decide if it was figuring that the igloo is also at room temp. For what it's worth I'm going to be doing a California Common.
