what is a lauter tun

Welcome to Hebei YUBO Filtration Equipment Co.,Ltd.

Behind every pint of delicious, frothy beer lies a complex and precise brewing process. While many beer enthusiasts are familiar with the primary ingredients - water, malt, hops, and yeast - several crucial steps transform these raw materials into the beloved beverage we all enjoy. One such step in the brewing process is the use of a Lauter Tun. In this blog, we will delve into what a Lauter Tun is, its role in beer brewing, and its work principle in producing high-quality brews.


The Lauter Tun is typically a large, cylindrical vessel made from stainless steel or other food-grade materials.

What is a lauter tun?

The Lauter Tun is typically a large, cylindrical vessel made from stainless steel or other food-grade materials. The vessel is equipped with a wedge wire false bottom or a slotted plate, which serves as a filter bed to support the spent grains while allowing the liquid wort to pass through.

In the world of brewing, a Lauter Tun is an essential vessel used primarily during the mashing process, which extracts fermentable sugars from the malted grains. It is a specialized vessel designed to separate the sugary liquid, known as wort, from the solid remnants of the malted grains known as "spent grains" or "mash." This process is a crucial step in the beer brewing process, as it determines the flavor, color, and body of the final product.

How does a mash lauter tun work?

1. Mashing: During the mashing process, hot water is mixed with crushed malted grains in a separate vessel called the Mash Tun. This mixture creates a porridge-like substance known as "mash," which contains fermentable sugars, proteins, and other soluble compounds.

2. Transferring to the Lauter Tun: Once the mashing process is complete, the mash is transferred to the Lauter Tun. The stainless steel false bottom in the Lauter Tun acts as a sieve, providing a solid surface to support the grain bed while allowing liquid to pass through.

3. Lautering: The next step is known as "lautering." During this process, hot water, known as "sparge water," is gently sprayed over the top of the grain bed. The sparge water trickles down through the grain bed, rinsing out the remaining sugars and soluble compounds in the process.

4. Wort Collection: As the sparge water passes through the grain bed, it combines with the sugars and soluble compounds, forming the sweet liquid known as "wort." The wort flows through the false bottom and is collected in a vessel below the Lauter Tun, ready for the next stage of the brewing process, which is boiling and adding hops.

5. Spent Grain Removal: Once the wort has been collected, the remaining solid grains, now devoid of most sugars and soluble components, are removed from the Lauter Tun. These spent grains can be repurposed as animal feed or for other uses.

The Lauter Tun is an indispensable tool in the beer brewing process. Separating the sugary wort from the solid remnants of the malted grains plays a pivotal role in shaping the flavor, color, and body of the final beer product. The use of a Lauter Tun ensures efficient sugar extraction, clarifies the wort, and contributes to the beer's overall flavor profile and consistency.
