Lautering is the brewing process in which the mash (spent grain) is separated/removed from the clear, sweet liquid wort. Lautering usually consists of 3 steps: 1) mashout (halting conversion of starches to fermentable sugars), 2) recirculation (drawing off wort from the bottom of the mash to add it to the top), and 3) sparging (separating the sugars from the grains). The lauter tun is traditionally the vessel where these steps occur.
With Portland Kettle Works’ brewing systems, we generally recommend combining the mash and lauter tuns to increase efficiency and reduce cost. However, if desired, PKW can deliver any system with separate mash and lauter tuns.
All PKW lauter tuns are manufactured to exacting standards:
