Today in 2013, US Patent 8601936 B2 was issued, an invention of Ian Stuart Williams and Anders Gordon Warn, assigned to Williamswarn Holdings Limited, for their “Combined Brewing System.” Here’s the Abstract:
A combined brewing system for small scale brewing of fermented alcoholic beverages, particularly beer, and to a method of making fermented alcoholic beverages. The brewing system comprises a single pressurizable vessel. The beer is naturally carbonated to the desired level during fermentation. Sediment is collected and substantially separated from within the vessel and removed from the vessel while the vessel is under pressure. Compressed gas is added for maintaining natural carbonation levels, so that the contents of the vessel can be drawn off at a desired pressure. The vessel has a temperature control system to selectively control the temperature during processing.
