During the mash step, starches in malted barley get converted into fermentable sugar, which then get rinsed from the grains during the sparge step. It's commonly said that the ideal temperature of the sparge water is 170˚F/77˚C, though some have experimented with sparging with cooler water. In this episode, contributor Cade Jobe joins Marshall to discuss the merits of cool sparging as well as the results of an exBEERiment on the method.
