Which grape variety is known for its high acidity and is often used in sparkling wines?

Chardonnay is well-regarded for its high acidity, making it an ideal grape variety for sparkling wines. This characteristic acidity is crucial in the production of sparkling wines because it helps retain freshness and balance the sweetness of any dosage added after fermentation. The bright acidity found in Chardonnay contributes to the crispness and overall structure of the wine, enhancing its aging potential and ability to pair well with a variety of foods.

Moreover, Chardonnay is the primary grape used in the traditional method of sparkling wine production, particularly in regions like Champagne, where it plays a significant role in creating complex flavors alongside its inherent acidity. While other varieties like Pinot Noir also contribute to sparkling wines, particularly in blends, Chardonnay is specifically celebrated for its acidity in this context.
