A stout manufacturing process

A stout manufacturing process includes delivering preset quantities of malt, roast material which includes roast barley and water to a mash tun (45). The materials are mixed in the mash tun (45) to prepare a sweet wort. The sweet wort is delivered through a lauter tun (46) for removing solid materials. Downstream of the lauter tun (46) hops are added to the sweet wort and boiled with the sweet wort in a wort copper vessel (48) to prepare a hopped wort. The hopped wort is cooled in a heat exchanger (52) to about 18{ C and delivered through a cold wort line (53) into a fermenting vessel (54). Sterile air and yeast are injected into the cooled hopped wort in the cold wont line (53). The mixture in the fermenting vessel (54) is fermented in a controlled manner to form a stout which is then matured in a storage vessel (58) at a selected temperature and pressure. The stout is centrifuged (60) to remove solid materials and the thus clarified stout is stored in a bright stout tank (62) from where ...

A stout brewing process

A stout brewing process includes delivering pre-selected quantities of two or more brewing varieties of barley malt, roast barley, chocolate malt and water to a mash tun (45) to prepare a mash. The materials in the mash tun (45) are mixed to prepare a brew. The starch in the brew is converted to sugar to prepare a sweet wort in a number of steps of desired duration and temperature. The sweet wort is delivered to a lauter tun (46) where solid material is removed from the sweet wort which is then boiled with hops in a wort copper vessel (48) to prepare a hopped wort. After boiling, hop residues are removed and the hopped wort is cooled in a heat exchanger (52). Yeast and sterile air are added to the hopped wort and the mixture thus produced is fermented in a fermentation vessel (54) to produce stout. The stout after maturing is filtered and conditioned prior to packaging.
