What is the main ingredient in a traditional Mimosa?

In a traditional Mimosa, the main ingredients are Champagne and orange juice. This classic brunch cocktail is known for its refreshing and light taste, combining the bubbly character of Champagne with the citrusy sweetness of orange juice. The choice of Champagne is significant because it contributes a unique flavor profile and effervescence that balances nicely with the acidity and sweetness of the orange juice.

Mimosas are popular due to their simplicity and are often enjoyed during celebrations and brunches. The traditional preparation involves a specific ratio of the two ingredients, typically equal parts, allowing both flavors to shine. While variations exist that might include other types of sparkling wine, the traditional version adheres to the Champagne-orange juice pairing. This distinction makes the correct answer clear when considering what defines a Mimosa.
