Patent No. 698184A: Method Of Refining, Aging, Mellowing, And Purifying Alcoholic Liquors

April 22, 2016 By Jay Brooks

patent-logo
Today in 1902, US Patent 698184 A was issued, an invention of James Franklin Duffy, for his “Method of Refining, Aging, Mellowing, and Purifying Alcoholic Liquors.” Although it’s not strictly speaking, a beer patent, it is somewhat related, and it was too interesting not to include. There’s no Abstract, although in the description it includes this summary:

My invention relates to a certain improved method or process for the treatment of liquors in the same particulars as is usually accomplished through a considerable period by the ordinary aging process.

Under the term liquor as used herein I include all alcoholic or spirituous fluids, either distilled or fermented; and it is the purpose of the invention to purify said liquors,to eliminate all injurious qualities therefrom, and to supply the ripe, pure, and mellow qualities which time alone has done heretofore.

The invention consists in the treatment of the liquor by means of the various steps of the process, all of which will appear from the description and be clearly pointed out in the claims.
