Today in 1999, US Patent 5906151 A was issued, an invention of Adam Firestone, Jeffers Richardson, Donald E. Othman, and Michel A. Blom, assigned to Firestone Walker, LLC, for their “Apparatus And Method For Brewing An Alcoholic Beverage and Beverage Brewed by Same.” Here’s the Abstract:
An apparatus for brewing an alcoholic beverage includes a plurality of wooden barrels including at least one first wooden barrel, at least one second wooden barrel, and at least one third wooden barrel; an enclosed trough; a plurality of first conduits providing flow communication between each of the plurality of wooden barrels and the enclosed trough; an enclosed catch pot in flow communication with the enclosed trough; a plurality of second conduits providing flow communication between the enclosed catch pot and each of the plurality of wooden barrels; and devices, such as valves, for controlling flow between each of the plurality of wooden barrels and the second conduit. The at least one first wooden barrel is a new barrel that has been filled with an alcoholic beverage up to 5 times, the at least one second wooden barrel is a middle aged barrel that has been filled with an alcoholic beverage from 6 to 12 times, and the at least one third wooden barrel is an old barrel that has been filled with an alcoholic beverage from 13 to 30 times.
This is essentially a patent for Firestone Walker’s modified Burton Union System that they pioneered when they first started, and then scaled-up when they bought the old SLO Brewery in Paso Robles and increased the size of their beer production. Jeffers, of course, is still there is the Barrelmeister, or Director of the Firestone Walker Barrelworks. That system is one of only two such brewing systems left in the world, the other being at Marston’s in Burton-on-Trent in England.
Here’s a few photos of the system at the Paso Robles brewery in 2012.
