Rolling Rock is a 4.4% abv American lager launched in 1939 by the Latrobe Brewing Company. Although founded as a local beer in Western Pennsylvania, it was marketed aggressively and eventually became a national product. The brand was sold to Anheuser-Busch of St. Louis, Missouri, in mid-2006, which transferred brewing operations to New Jersey while continuing to label the new beer prominently with the name of Latrobe.

Latrobe Brewing Company was founded in 1893 in Latrobe, Pennsylvania as part of the Pittsburgh Brewing Company. Forced to close in 1920 due to prohibition, it was purchased by the Tito brothers and reopened in 1933 selling “Latrobe Old German” and “Latrobe Pilsner” beers. The year 1939 saw the introduction of Rolling Rock beer and Latrobe became one of the largest breweries in the United States. It was purchased by Labatt Brewing Company in 1987, which in turn was purchased in 1995 by the Belgian brewing conglomerate corporation Interbrew, which merged later into InBev in 2004.
