Abstract
Brewing apparatus for batch brewing beer or ale comprises a fermentation vessel 1 in which a fermentable liquor is contained, a float hydrometer 11 and a sensor 12 for monitoring downward displacement of the hydrometer 11 as the specific gravity of the liquor reduces due to fermentation. The sensor 12 includes means for providing a signal in a controller 3 at a desired specific gravity to indicate completion of the required fermentation and the controller 3 is operable to control automatic transfer of the fermented liquor to a maturing vessel 4 and, after a predetermined time interval to a barrel or the like.
Claims19
Brewing apparatus for batch brewing beer or ale wherein a fermentation vessel is arranged to contain a quantity of liquor, a float hydrometer has a stem receivable within a sensor mounted in the vessel and arranged to limit upward displacement of said hydrometer, said sensor including means responsive to downward displacement of said hydrometer stem, and a controller connected to said sensor, the arrangement being such that, in use, with said vessel filled with liquor having a high specific gravity, said stem of said hydrometer is received within said sensor and, as the specific gravity of the liquor reduces due to fermentation, said hydrometer stem is displaced downwardly from said sensor until, at a desired specific gravity, said sensor means responds to provide a signal in said controller for indicating the desired completion of fermentation.
