A Study of American Beers and Ales

A meticulous early‑20th‑century investigation into the chemistry of American beers and ales, this bulletin records a collaborative effort between government chemists and several commercial breweries. The authors set out to compare beers brewed solely from malt with those that incorporate adjunct grains such as rice, corn, and cereals, gathering real‑world samples straight from the production line rather than laboratory recreations.

The study follows each brew step‑by‑step—mashing, boiling, hopping, fermenting, and storage—while noting exact quantities, temperatures, and timings. Detailed analytical methods are applied to the collected wort and finished beer, producing a wealth of data on composition, gravity, and nutrient content. Listeners will gain insight into the rigorous scientific approach used to map how raw ingredients shape the character of the brew, offering a rare glimpse into the foundations of modern beer quality control.
