Which of the following is NOT an authorized ancillary grape variety of Champagne?

• A. Pinot Blanc
• B. Arbane
• C. Petit Meslier
• D. Chardonnay

Answer: (D)

In Champagne, there are three principal grape varieties that form the backbone of most blends: Chardonnay, Pinot Noir, and Pinot Meunier. Beyond these, a small group of ancillary (or other) varieties is permitted to add different characters to a cuvée. The commonly recognized ancillary grapes include Arbane, Petit Meslier, Pinot Blanc, and Pinot Gris. These are used in smaller amounts and aren’t the primary building blocks of most Champagnes.

Among the options, Chardonnay is the grape that does not belong to the ancillary group. It is one of the main varieties used in Champagne, not an additional or secondary grape. That’s why Chardonnay is the correct answer. The other three options are part of the ancillary category and thus are authorized as such, though in smaller proportions.
