Wahl-Henius Institute Of Fermentology is a brewing research laboratory and school in Chicago that operated between 1886 and 1921.
Founded in 1886 by Dr Robert Wahl and Dr Max Henius as the Wahl & Henius, the name was changed to the Scientific Station for Brewing of Chicago and then to the Institute of Fermentology before becoming the Wahl-Henius Institute. Its educational division, the American Brewing Academy, was created in 1891.
The school and laboratory operated successfully until Prohibition, when the near dissolution of the brewing trade forced its closure and sale to the American Institute of Baking, which retains the nucleus of the Wahl-Henius library.
Wahl-Henius would perhaps be mostly forgotten today if it were not for its role as publisher of two important beer texts. The Wahl-Henius Handy Book of Brewing, Malting and the Auxillary Trades, coauthored by Wahl and Henius, is a comprehensive and wide-ranging view into American brewing in 1901. It also contains basic chemical analyses of many contemporary American and European beers, providing an unusually valuable window into the brewing past. J. P. Arnold’s 1911 Origin and History of Beer and Brewing is an exhaustive romp through thousands of years of beer history.
