Root, the first original American liqueur since Prohibition and its PA origins:
ROOT traces its heritage all the way back to the 1700s when colonists were first introduced to the Root Tea that Native Americans would drink as an herbal remedy. Brewed from sassafras, sarsaparilla, wintergreen birch bark, and other roots and herbs, Root Tea was used to cure a variety of ailments. As colonial settlers passed the recipe down form generation to generation, the drink grew in potency and complexity. This was especially true in the Pennsylvania hinterlands where the ingredients naturally grew in abundance. These homemade, extra-strong Root Teas were a favorite in colonial homes and public houses all over the northeastern colonies.
