Butterfly is the first pre-ban absinthe of American origin to return to the USA. It was originally made in Boston circa 1902 at the Dempsey Distillery on Merrimac Street. The brand was resurrected by Boston-based absinthe historian, Brian Fernald. An empty bottle and the 1905 trademark registration helped give Fernald a label design and, after years of research in local archives, he unearthed Dempsey's handwritten recipe book.
