The Gin & Tonic is a classic cocktail made by mixing gin with tonic water, typically served over ice and garnished with a slice of lime or lemon. The drink is known for its refreshing taste, combining the herbal and botanical flavors of gin with the crisp, slightly bitter notes of tonic water. Originating in the 19th century, the Gin & Tonic became popular among British soldiers in tropical regions as a way to consume quinine, a malaria treatment found in tonic water. Today, it remains a favorite beverage worldwide, enjoyed for its simplicity and versatility.
