Stage 3 - Lautering

The mash is transferred to the Lauter tun, where the liquid extract is separated from the barley husks to give a clear “wort”. The wort is recirculated until the grain forms a natural filter bed. Then the clear extract is removed back to the kettle. Hot water is sprinkled on top of the grain bed to leach out any remaining sugar. After draining, the spent grain is removed and can be used as supplementary feed for cattle.
