Which grape varieties used in champagne production?

* Chardonnay: This white grape variety produces wines known for their acidity, elegance, and aging potential. It contributes aromas of citrus, apple, and toast.

* Pinot Noir: This red grape variety contributes red fruit flavors, structure, and tannin to Champagne. It's responsible for the red wine base used in Blanc de Noirs (100% Pinot Noir) Champagne.

* Pinot Meunier: This red grape variety is known for its early ripening and fruit-forward character. It contributes aromas of red berries, cherry, and spice.

These three grapes are blended in varying proportions to create the unique style of Champagne. The exact blend depends on the producer and the desired style of Champagne.

Other grape varieties allowed in Champagne production:

* Arbane: This rare white grape variety adds floral and citrus notes.

* Petit Meslier: This white grape variety contributes delicate floral aromas.

* Pinot Blanc: This white grape variety adds complexity and minerality.

However, these other varieties are rarely used and are not as prevalent as the main three.
