A gin and tonic is a popular cocktail made by mixing gin, a distilled alcoholic beverage, with tonic water, a carbonated drink that contains quinine. The drink is typically served over ice and garnished with a slice of lime or lemon, enhancing its refreshing flavor. The origins of the gin and tonic date back to the 19th century when British colonial officers in India mixed gin with tonic water to make the bitter tonic more palatable while also benefiting from its medicinal properties. Today, it is enjoyed worldwide for its crisp and invigorating taste.
