|The Mash Tun is a 10 gallon
Rubbermade cooler. The cooler has a removable grain screen
and brass fittings for your mashing enjoyment.
Mashing in a cooler is superior to a stainless steel keg for two
reasons. First, it doesn't weigh as much, and second it is
insulated. The insulation allows you to reach your target
temperature more quickly, and use less energy to hold it there.
