Yards Brewing Company, based in Philadelphia, has an "Ales of the Revolution" series with beer recipes based on those used by George Washington, Benjamin Franklin, and Thomas Jefferson.
I tried the "Thomas Jefferson Tavern Ale" which was good, Belgian-y but with a light body.
I'm curious to try the "Poor Richard's Tavern Spruce Ale" which uses molasses in place of barley malt and spruce in place of hops.
