Which spirit serves as the base for El Diablo?

• A. Vodka
• B. Gin
• C. Tequila
• D. Rum

Answer: (C)

The main idea here is recognizing the base spirit—the ingredient that provides the drink’s primary character and flavor backbone. For El Diablo, that backbone comes from tequila. Tequila brings a distinctive agave-forward bite and crisp edge that defines the drink’s overall profile, and it holds up against the other components without being overwhelmed by them.

The other ingredients play supporting roles: crème de cassis adds a fruity sweetness and color, lime juice provides bright acidity, and ginger beer brings fizz and a touch of spice. Together they complement the tequila rather than replace its influence.

If you used vodka, the cocktail would lose its defining agave character because vodka is relatively neutral. Gin would introduce strong botanical notes that could clash with the cassis, lime, and ginger beer. Rum would push the flavor toward a sweeter, tropical direction that isn’t characteristic of El Diablo.
