Margaritas balance sweetness and strength, making them popular among many drinkers. On average, a standard margarita contains approximately 3 ounces of liquid. About 2 to 2.5 ounces consist of alcohol, primarily tequila, alongside a dash of lime juice or mixer and some water from melted ice. Considering 80-proof tequila and accounting for mixers and ice melting, margaritas typically have an alcohol by volume (ABV) of approximately 33%.
