Mount Vernon George Washington erected a stone gristmill in 1771 to increase production of flour and cornmeal and to be able to export high quality flour to the West Indies, England, and Europe. In 1797, Washington's Scottish farm manager James Anderson encouraged him to build a whiskey distillery adjacent to the gristmill. The distillery was the largest in America, producing 11,000 gallons of whiskey in 1799, making it one of the most successful economic enterprises at Mount Vernon.
Demonstrations of the mill are given by millers in early-American attire from 10 a.m. to 5 p.m. Entrance to the site is included in admission to George Washington's Mount Vernon. Admission to the Distillery & Gristmill is also sold separately for $5 for adults, $2 for youth ages 6-11, and free for children 5 and under.
