Today in 1995, CA 2133272 A1 was issued, an invention of Charles J. Koch, though the “Applicant” is listed as Charles J. Koch, Boston Beer Company Limited Partnership D/B/A Boston Beer Company (The), A Massachusetts Partnership; General Partner, Boston Brewing Company, Inc., for his “Preparation Of Beer.” Here’s the Abstract:

High alcohol beer having a full, round flavor is prepared by employing as the yeast a wine or champagne yeast, and a sweetened wort.

While I can’t be sure, I think this is essentially for Samuel Adams’ Triple Bock, which was first released in 1994. While the patent wasn’t granted until 1995, it was filed in the fall of 1994, but the “priority date” listed is October 6, 1993. The “inventor” listed is Charles J. Koch, who was Jim Koch’s father, although under “applicant” the Boston Beer Co. is also listed. In addition, I recall Jim explaining that it was in fact Champagne yeast that was used to create the beer. So it certainly seems likely that they patented the process used to make that unique beer. I still have a few bottles of it in my cellar though the last couple I opened tasted a lot like soy sauce. To be fair, the bottles that were opened during an anniversary dinner that I was lucky enough to attend in Boston Beer Co.’s barrel room a few years ago were tasting quite good. Although the OCR errors make it difficult reading, it’s still interesting to see the thought process and how they went about it laid out. I may have to open another bottle soon.
