The Aviation is a classic gin sour known for its floral and slightly tart profile. Profile: * Floral, citrusy, lightly sweet, with subtle cherry and violet notes Origin: * Early 1900s, created by Hugo Ensslin in New York * First appeared in Recipes for Mixed Drinks (1916) Quick note: Crème de violette is powerful, too much makes the drink taste soapy/perfume-heavy, which is why many modern specs keep it low.
