Based on sales in 2011, Yuengling was tied with the Boston Beer Company, maker of Samuel Adams brands, as the largest American-owned brewery. Its headquarters are in Pottsville, Pennsylvania. Yuengling produces about 2.8 million barrels annually, operating two Pennsylvania facilities and a brewery in Tampa, Florida.
Yuengling is an Anglicized version of Jüngling, its founder's surname and the German term for "youngling" or "young person” or simply, “youngster”.
The family-owned brewery has traditionally changed ownership through the purchase of the company by the offspring of the previous owner. Due to the popularity of Yuengling Traditional Lager in Pennsylvania and the Delaware Valley (including South Jersey), in some bars it can be ordered by simply asking for a lager.
