D. G. Yuengling & Son is the oldest operating brewing company in the United States, established in 1829. It is one of the largest breweries by volume in the country. 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 2.5 million barrels annually, operating two Pennsylvania facilities, and a brewery in Tampa, Florida. Frank Yuengling began heading the company in 1899 after his father Frederick died. During the Prohibition era, Yuengling survived by producing "near beers" called "Yuengling Special", "Yuengling Por-Tor", and "Yuengling Juvo".
The company also ran a dairy which produced ice cream and opened dance halls in Philadelphia and New York City. After the 18th Amendment was repealed in 1933, Yuengling sent a truckload of "Winner Beer" to President Franklin D. Roosevelt in appreciation, which arrived the day the amendment was repealed; particularly notable since Yuengling beer takes almost three weeks to brew and age. Richard L. Yuengling and F. Dohrman Yuengling succeeded Frank Yuengling after their father's death in 1963.
