The vessel in which lautering takes place. It is usually fitted with either a false bottom or a manifold in order to facilitate the rinsing of the grains.
The vessel used in brewing between the mash tun and the brew kettle. It separates the barley husks from the clear liquid wort. The barley husks themselves help provide a natural filter bed through which the wort is strained.
Any vessel used to hold all-grain brewing ingredients during the lauter ( sparge). Lauter tuns must contain a false bottom to allow drainage of sweet wort while retaining the grain bed. However, anything from a brewing kettle to nested plastic buckets will do, provided a false bottom set-up is created. Many lauter tuns are equipped with sprinklers above the grains to allow an even spray of sparge water over the grain bed.
