Straub Brewery, was founded in St. Marys in 1872 by Peter Straub (1850-1913) of Felldorf, Württemberg, Germany, who purchased the Benzinger Spring Brewery from his father-in-law, Francis Xavier Sorg. Brewing continuously since that time, Straub is the third oldest brewery in the United States and considered an American Legacy Brewery™. It is still owned and operated by the original founding family, now in its seventh generation. Straub is also the smallest pre-Prohibition brewery still in business in the United States.Tours of the brewery include a stop at the "Eternal Tap," at which a person can drink a free glass of Straub beer.
