A Margarita belongs to which cocktail family?

A Margarita is categorized under the cocktail family known as Sours. This classification is due to its foundational structure, which typically includes a combination of a base spirit (in this case, tequila), citrus juice (usually lime), and a sweetener (often orange liqueur like Cointreau or triple sec).

The Sours category is defined by the balance of acidity from the citrus juice and sweetness from the liqueur or syrup, creating a refreshing and zesty flavor profile. The Margarita exemplifies this balance, making it a quintessential representative of Sours, as the tartness of the lime juice plays a crucial role in the drink's overall taste.

In contrast, the other cocktail families mentioned—Fizz, Mules, and Collins—have distinct ingredients and characteristics. Fizzes typically involve carbonated water and achieve their refreshing quality through effervescence. Mules are characterized by their use of ginger beer along with a spirit, usually served in a copper mug, while Collins cocktails include a base spirit, lemon juice, and soda water but differ in their overall presentation and flavor profile.
