D. G. Yuengling & Son, established in 1829, is the oldest operating brewing company in the United States. In 2018, by volume of sales, it was the largest craft brewery, sixth largest overall brewery and largest wholly American-owned brewery in the United States. Its headquarters are in Pottsville, Pennsylvania. In 2015, Yuengling produced about 2.9 million barrels, 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 a "young person” or “youngster”.
The family-owned brewery has traditionally changed ownership through the purchase of the company by the offspring of the previous owner. Though it is an amber lager, Yuengling Traditional Lager is popular enough in Pennsylvania and the Delaware Valley to be ordered in some bars by simply asking for a lager.
