The cocktail known as Sex on the Beach is as famous for its provocative name as it is for being refreshing and fruity. Its origins are lost and when or where the drink was first made is unknown. Popular liquor lore gives credit to a bartender in Florida who created it in 1987 as part of a promotion to sell peach schnapps by a liquor company. This is belied, however, by the fact that the drink was already included in the 1982 edition of the 'American Bartenders School Guide to Drinks'.
Arguments about origin aside, some consider the cocktail to have been invented from a combination of a cocktail called a Fuzzy Navel (consisting of orange juice and peach schnapps) with a drink called the Cape Codder (consisting of cranberry juice and vodka). The combination of these drinks accounts for the constituents of the Sex on the Beach cocktail. While some recipes call for a small amount of crème de cassis, this is considered entirely optional.
