"The Inspiring History and Legacy of American Lager Beer" is envisioned to be a nine-volume series of books covering the history of the American lager brewing industry from the 1840s to the 1940s and the evolution of adjunct lager beer as America’s “national beverage.” The “surprising” aspect of this history is that it ever happened at all, given the half-century-long assault on the industry between the 1870s and 1910s to impose an “American Reinheitsgebot.” Unified in this objective were a plethora of the nation’s political, cultural, and agricultural institutions—all seeking to ban to use of rice and corn-based products in the brewing of American ales and lagers. Equally united in opposition to this effort were the brewers and brewing scientists of America. In battles that were passionate, highly public, and intense in nature, these brewing industry advocates successfully defended the right of American brewers to brew with the ingredients of their choice. It is a powerful legacy not only for America’s first revolution in beer (the adjunct lager brewing industry) but also for the nation’s second revolution in beer (the American craft brewing industry).

Biotransformation has become a buzzword in the brewing community, with many brewers even performing dry hopping at certain specific times to hit what is considered to be the “biotransformation sweet spot.” Academic literature does not support these claims. With the aid of enzymes developed for the wine industry, two experimental IPA beers were brewed: one with an enzyme preparation aimed at hydrolyzing glycosides and the other with a β-lyase preparation aimed at releasing bound thiols. Triangle tests for each treatment were carried out by a panel of over 25 participants, composed of brewers and judges, and showed that both beers were significantly different from the control, yet preference was overwhelmingly toward the no-enzyme IPA control beer. Furthermore, the descriptive analysis carried out by the same panel showed a clear trend toward both enzyme beers being less tropical/fruity and more herbal and/or citrusy, the exact opposite of the purported benefit of biotransformation.
