What is the primary ingredient in a Moscow Mule?

The primary ingredient in a Moscow Mule is vodka. This classic cocktail typically includes vodka, ginger beer, and lime juice, served in a distinctive copper mug. The vodka provides the base spirit and contributes to the drink's smooth and refreshing profile, allowing the spicy and sweet notes of the ginger beer and the tartness of the lime to shine. This combination is what makes the Moscow Mule a popular choice for many cocktail enthusiasts, highlighting vodka's versatility as a spirit in mixed drinks.

Rum, gin, and tequila are not used in this particular cocktail, as each of these spirits has its own unique flavor profiles that would not complement the ginger beer and lime in the way that vodka does.
