LAUTERING

After the mash’s starches have converted to simple sugars and all the colors and flavors have leached from the grist the entire mash is pumped over to the Lauter Tun. The Lauter Tun separates the spent grain solids from the wort through a screen like bottom.  More hot water is gently  sprayed over the mash bed to rinse out any remaining sugars and flavors.  This process is called spargin. The spent grain solids are sent off to dairy farms for feed.
