George Washington’s Gristmill at Mount Vernon is open seven days a week, April through October. George Washington's Gristmill returned to the grind, and became a part of Mount Vernon, in 2002 after five years of research and restoration work conducted by Mount Vernon. Visitors see an 18th-century water-powered mill in operation, discover how it works, and learn how this particular mill played an important role in George Washington's vision for America's future as "granary to the world." Costumed millers discuss the character and accomplishments of George Washington – one of the nation’s most innovative and successful farmers. Adjacent to the Gristmill is George Washington's reconstructed Distillery. Admission to the Distillery & Gristmill site is included in the Estate general admission tickets.
