Three miles south of his estate Mount Vernon, on Rte 235, you’ll find George Washington’s Distillery & Gristmill , which was also part of the president’s estate. Although Washington’s leadership skills were well known, his prowess at farming and making whiskey were less discussed. He also patented a milling system – and you can purchase stone-ground cornmeal from the shop. The museum has exhibits, a film on Washington’s whiskey, and actors in period costume demonstrating how it all worked.
