For 126 years, Heineman’s Winery has been owned and operated by the Heineman family on Put-in-Bay. In 1888 when Gustav Heineman founded the winery, there were 17 wineries on Put-in-Bay. Now there remains one functioning winery: Heineman’s. It is the oldest family owned and operated winery in Ohio.
During the time of prohibition, which was 1920-1933, most of the wineries on Put-in-Bay closed. Heineman’s Winery stayed open selling grape juice and offering tours of the many caves on Put-in-Bay with taxi service included. At that time there were three caves that the Heineman family managed: Crystal Cave (which is still functioning today), Mammoth Cave and Paradise Cave.
