French Martini is a cocktail made with Vodka, Crème de cassis Liqueur, and Pineapple Juice. The drink is often served in a champagne flute. The French Martini was created in the 1980s by bartenders in New York City. The drink became popular in the 1990s, and has since become a staple of cocktail culture. The French Martini is a refreshing and slightly sweet cocktail. The vodka provides a smooth base, while the crème de cassis adds a tartness that is balanced by the sweetness of the pineapple juice. Cheers!
