Politicians by day and beer drinkers by night, our Founding Fathers clearly appreciated a good brew. Philadelphia’s own Yard's Brewing Company has created ales based on 18th-century recipes made by eminent figures like George Washington and Thomas Jefferson. Join the Historical Society of Pennsylvania and the Chemical Heritage Foundation (CHF) for a tasty history lesson in the art and science of re-creating Revolutionary-era ales led by CHF's rare-book curator (and avid home brewer), James Voelkel. Peruse the HSP pop-up exhibit including copies of documents from the period, including a selection Revolutionary-era beer recipes and David J. Kennedy watercolors of some of Philadelphia’s most popular alehouses
