Today in 2012, just three years ago, US Patent 20120000367 A1 was issued, an invention of Rudolf Michel and Ludwig Scheller, for a “Brewery Facility for Producing and Bottling Beer.” Here’s the Abstract:

The invention relates to a brewery plant (12) for producing and bottling beer, comprising a brewhouse facility (01) in which wort is produced from raw materials while employing process energy, and further comprising a bottling facility (02) in which beer produced from the wort is filled into packaging containers, in particular bottles, while employing process energy, wherein in order to supply the brewhouse facility (01) with process energy a first energy supply network (16) is provided, into which process heat having a first temperature level is fed from at least one first energy generation facility (17) and is distributed by a heat transfer means to different energy consumers (14, 15) in the brewhouse facility (01), and wherein in order to supply the bottling facility (02) with process energy a second energy supply network (21) is provided, into which process heat having a second temperature level is fed from at least one second energy generation facility (22) and is distributed by a heat transfer means to different energy consumers (23, 24, 25) in the bottling facility (02), wherein the maximum temperature of the heat transfer means in the first energy supply network is above the maximum temperature of the heat transfer means in the second energy supply network.
