What is the primary characteristic of Cava compared to Champagne?

Cava is primarily characterized by the use of different grape varieties compared to Champagne. In the production of Cava, especially those from the traditional Catalonia region in Spain, the predominant grapes used include Macabeo, Xarel-lo, and Parellada. This differentiates Cava not only from Champagne but also contributes to its unique flavor profile and style.

While both Cava and Champagne undergo secondary fermentation in the bottle, the differences in grape varieties lead to variations in taste, aroma, and mouthfeel. Champagne typically relies on the traditional grapes of Chardonnay, Pinot Noir, and Pinot Meunier, which impart distinct characteristics associated with the Champagne region, such as richness and complexity.

Understanding the grape varieties used in each sparkling wine is essential for recognizing their regional styles and characteristics. This focus on grape varietal differences underscores why the correct answer highlights Cava's distinction based on its primary grape composition.
