Aviation is a classic cocktail created in the early 20th century and made particularly famous by 'Recipes for Mixed Drinks' by Hugo Ensslin in 1916. The drink is a tribute to the rise of aviation and has a unique blue-purple hue, which comes from the unusual ingredient crème de violette. The combination of gin, maraschino liqueur, fresh lemon juice and crème de violette gives a distinctive floral and tart flavor profile. Aviation is an elegant and sophisticated cocktail that has become a favorite among connoisseurs and a symbol of the early days of mixology.
