Wedge Wire Screen False Bottom in Lauter Tun

Lautering refers to the process of separating sweet wort from the grain bed. In commercial breweries, the mash is frequently pumped from the mash tun to a dedicated lauter tun, freeing the mash tun for a new brew. Homebrewers typically mash and lauter in the same vessel, called a mash-lauter tun, or MLT.


Lauter comes from the German word abläutern, meaning roughly “to rinse off” or purify. Lautering refers to the process of separating sweet wort from the grain bed. In commercial breweries, the mash is frequently pumped from the mash tun to a dedicated lauter tun, freeing the mash tun for a new brew. Homebrewers typically mash and lauter in the same vessel, called a mash-lauter tun, or MLT. The key piece of equipment that enables a mash tun to do double duty as a lauter tun is the false bottom, screen, manifold, or braid.


Lauter Tun is a vessel for separating the wort from the solids of the mash. A lauter tun works much like a large sieve. It normally has a slotted, perforated floor, also called a false bottom, which holds the spent milled grains, while allowing the wort to filter through the grain bed and collect in the space beneath; the wort then runs to the brew kettle. False bottom is an important part for a Lauter Tun. wedge wire false floor allows the purification of the beer. As all the slot of false bottom is very narrow and accurate to allow solid away from the liquid. And there is no block with the outstanding structure. 


Mashing occurs in a separate mash mixer, in which case the mash must be transferred by a pump to the lauter tun. The mash is usually pumped in from the bottom or side of the vessel to avoid excessive aeration of the mash. At the beginning of the run-off, the wort is usually recalculated through the grain bed as a filter mass, until the run-off appears clear through a sight glass in the recirculation plumbing. Unless sized for brewpubs or very small microbreweries, most lauter tuns are fit with motorized rakes that cut through the grain bed to give it greater filterability.
