What is the main component used to fill a Long Island Iced Tea cocktail?

The main component used to fill a Long Island Iced Tea cocktail is sour mix and Coke. This cocktail is known for its combination of multiple spirits—vodka, gin, rum, tequila, and triple sec—but what sets it apart is the addition of sour mix and cola. The sour mix provides a tart and sweet balance to the high alcohol content, while the cola mimics the color and some flavor aspects of iced tea, contributing to the drink's name. The combination of these ingredients results in a refreshing and deceptively strong cocktail that can easily be mistaken for a simple tea beverage.

Other options like club soda, pineapple juice, and orange juice are commonly used in different cocktails but do not define the Long Island Iced Tea. Using club soda would dilute the strong flavors of the spirits without providing the sweetness needed, and the fruity flavors of pineapple and orange juice would alter the intended taste profile of a Long Island Iced Tea.
