Mahon, like Plymouth, is one of the few gins to have a geopgraphical designation. Gin de Mahon is made on the island of Menorca, one of the Balearic Islands which can be found to the East of the Spanish peninsula, and has been in production there since the 18th century. It can only be made from two ingredients: juniper and alcohol. For that reason, the Xoriguer gin is one of the purest juniper flavored gins available. By the 20th century, a number of brands began to emerge such as Xoriguer, increasing the popularity of the gin across all of the Balearic Islands. In 1997, the island's gin was given a Regional Designation of Origin 'Gin de Menorca', however this was later changed in 2010 to be 'Gin de Mahón'.
