Lauter Tun
This is the vessel that holds the grain during the sparge after the mash is complete. This vessel must also be able to withstand temperatures up to 175 °F (80 °C), and it should be tall enough that the grain bed will be about 12 inches deep (±4 inches). Many brewers (including most brewpubs) use their mash tun to lauter, but any vessel used as a lauter tun requires some sort of device at the bottom to prevent the grains from clogging the outlet. This device can be in the form of a false I recommend a 5 gallon igloo icechest with a false bottom.
