Lautering is the brewing process in which the mash (the mix of milled grain and water) is separated into the clear liquid wort and the residual grain. The lauter tun is the traditional vessel used for separation of that extracted wort. While the basic principle of its operation has remained the same since its early uses, technological advances have led to better designed lauter tuns capable of quicker and more complete extraction of the sugars from the grain. But don’t take our word for it. Listen to Wolfgang Roth of ROLEC Prozess-und Brautechnik GmbH. He explains how the lauter tun works to Stephanie Weins, owner of Blackstone Brewing Co. of Nashville, Tenn., during her trip to Chieming, Germany to inspect the equipment.
