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. History From 1939 until July 26, 2006, Rolling Rock was brewed at the Latrobe Brewing Company in Latrobe, Pennsylvania, a small city 34 miles southeast of Pittsburgh, Pennsylvania. As stated on the bottle, it was brewed with a distinctive soft local water in large glass-lined tanks, which were considered state-of-the-art at the time of its introduction (in part due to sanitation concerns). On May 19, 2006, Anheuser-Busch purchased the Rolling Rock and Rolling Rock Green Light brands from InBev for $82 million and began brewing Rolling Rock at its Newark facility in mid July, 2006. The final batch of Rolling Rock was shipped from Latrobe on July 31, 2006. Union leaders in Westmoreland County organized a nationwide boycott of Anheuser-Busch and InBev brands because of the move. Anheuser-Busch has said that Rolling Rock's original pledge on the label will be preceded by these words: "To honor the tradition of this great brand, we quote from the original pledge of quality." In July 2008, InBev reached a deal to acquire Anheuser-Busch, thereby returning ownership of Rolling Rock to InBev, now known as Anheuser–Busch InBev and based in Belgium. In 2009, Anheuser-Busch InBev announced that it was exploring the sale of the Rolling Rock brand. In 2015, Anheuser-Busch stopped brewing bottled Rolling Rock in glass-lined tanks. Only the canned beer was now being brewed using the traditional process. Pony bottle Rolling Rock's pony bottle had been very popular until its discontinuation, so much so that this had given rise to the folk etymology that "pony" is from the Rolling Rock horse logo. This is incorrect: the term pony in "pony of beer" has been used in the United States of America since the 19th century, predating Rolling Rock by over 50 years, and is due to the diminutive size; similar words include pony glass and pony keg. Indeed, advertising for Rolling Rock since the 1950s uses the term "pony bottle" generically, stating "... Rolling Rock is the Largest Selling 7 oz. Pony Bottle of Premium
