Lauter Tun Screen

Lauter Tun Wedge Wire Screen False Bottoms are used in the craft beer brewing process between the mash tun and the brew kettle.  The lauter tun separates the barley husks from the clear liquid wort.

Lauter Tun Wedge Wire Screen False Bottoms are used in the craft beer brewing process between the mash tun and the brew kettle.  The lauter tun separates the barley husks from the clear liquid wort. The barley husks provide a natural filter bed through which the wort is strained and drains out of the lauter tun as a clear liquid.
False bottom screens can be constructed using round support rods or rectangular support rods.

Wedge wire screen is the preferred false bottom for lauter tun tanks in many breweries.
The stainless steel wedge wire screen can be made in sections to fit through any man-way.  Typically, the wedge wire false bottom screen has .030" slot openings to hold back the solids and allow the liquid to pass through. 

UBOW Screen produces lauter screens for breweries, distilleries, and wineries, fulfilling this important component of the lauter tun, where the lautering process occurs. Constructed from industry-standard stainless steel wedge wire — with custom or standard slot opening sizes and screen configurations — our lautering screens provide strength, quality, and reliability in this key stage of the brewing, distilling, and winery process.

The wedge wire false bottom has been established as the ideal construction to allow the lautering process to occur properly and efficiently. A wedge wire screen is constructed from “V”-shaped stainless steel pieces, set across support beams at regular intervals — typically with openings of .028 inches or .030 inches. Though other slot opening dimensions can be used depending on specific requirements.

The lauter tun wedge wire screen allows the solid grain components of the mash to act as a filter to separate the wort. While the slot openings of the lauter screen false bottom don’t technically act as a filter in the process, they enable the most effective filtration to occur by supporting the grain, which itself becomes the filtering medium — holding back the smallest solids while allowing the wort to pass. A high-quality, tight tolerance construction is necessary to help ensure that the process occurs correctly and uniformly so that the resulting product — whether beer, liquor or wine — is not bittered or otherwise compromised by components that shouldn’t be part of the wort.
