Sparge Sparge derives from the Latin spargere meaning to sprinkle or scatter and refers to the practice of sprinkling hot water over the grain bed to rinse sugars off of the grains as wort is drained from the lauter tun Among brewers the definition of sparging expands to mean any means of rinsing sugar from grain As such it is usually divided into one of three methods
