Insulated Brew Kettle
Brew Your Own magazine on the effect of insulation on the mash tun I determined that just 1 inch of insulation would make a huge difference.
So, using some foam rubber that came with our patio table, I cut a wrap to go around my keg/kettle and a foam rubber lid that was 2 inches thick. A bungee cord to keep it in place completed the crude insulation blanket.
This worked better than expected! During a 90 minute mash I only had to remove the "blanket" and fire up the burner once. This mash stayed right at 152°F for the majority of the time and only varied between 154° and 148°; perfect for this mash at the low end of the range.
