Moxie or Moxie soda is a drink that's most common in New England, though its an acquired taste. It tastes
like Root
Beer at first, but the aftertaste is bitter. The reason the aftertaste is bitter is that one of the ingredients is some Gentian
Root Extract. In fact, Moxie was actually used as a type of medicine in the 20th Century because of the Gentian Root in it.
