LAUTER TUN is a tank where the wort, the sweet liquid extracted from the malt, is separated from the grain bed. Lauter tun works like a large sieve, with a slotted bottom that holds the grain while allowing the wort to filter through. Lauter tun can improve the clarity, efficiency, and consistency of the brewing process, as it removes the solids, stops the enzyme activity, and recycles the water. Lauter tun has a cylindrical body and a motorized rake system that cuts through the grain bed. Lauter tun is an essential component of the brewhouse, where the wort is prepared before boiling, hopping, and fermenting.
