The process of infusing cracked grains with hot water to extract the naturally forming sugars The temperature is varied through time to allow certain enzymatic processes to occur
(1) Rinsing the draff with hot water in the lauter tun in order to recover the sugar it holds (2) The entire process of obtaining clear sweet wort from the mash, including runoff, recirculation, and rinsing
