Four Vessel Brewing

Traditional decoction brewing method requiring a mash cooker, a mash tun, a lauter tun, and a kettle. Mashing is carried out in the mash tun, and starts at a low temperature while portions of the mash are taken out and boiled in the cooker and later returned to the mash tun, thus gradually raising the temperature of the entire mash. The mash is afterwards filtered in the lauter tun and the resulting wort is boiled in the copper kettle.
