What are 3 grapes used to produce champagne?

The three main grapes used to produce champagne are:

1. Pinot Noir: This red grape contributes body, structure, and tannins to the wine.

2. Chardonnay: This white grape provides acidity, freshness, and a floral aroma.

3. Pinot Meunier: This red grape adds fruitiness, roundness, and early maturity.

While these are the most common grapes, other varieties like Pinot Blanc and Arbanne may be used in small amounts.
