A separating vessel used to sparge a mash and separate clear wort from the residual grains. Differs from a mash tun in being wider with a larger floor area to give a faster run off. Lauter tuns also have stirring rakes to agitate the mash and may be used after the mash has been incubated in a cereal cooker with ajuncts. In this arrangements more mashings may be performed per day so increasing efficiency.
