Tonic water is a carbonated beverage that is often used as a mixer in cocktails. It has a distinctive bitter flavor and is known for its effervescence. Tonic water gets its unique taste from the presence of quinine, a compound derived from the bark of the cinchona tree. In addition to quinine, tonic water typically contains sweeteners, flavors, and carbonated water. It is commonly used as a mixer with gin to make the classic cocktail known as a gin and tonic. Tonic water can also be enjoyed on its own as a refreshing and fizzy beverage.
