Tonic water is a carbonated soft drink flavored with quinine, the compound that gives it its distinctive, clean bitterness. Originally developed in colonial India as a way to make quinine more palatable, modern tonic typically includes sweeteners and light citrus or botanical notes, with quinine levels regulated for safety.

Behind the bar it’s a foundational mixer, prized for the balance of bitterness, gentle sweetness, and lively effervescence. It pairs especially well with gin and other clear spirits, and benefits from fresh citrus and plenty of ice; styles range from classic to “dry” and diet versions that vary in sweetness and intensity.
