What is the term for a white champagne made from Pinot Noir and/or Meunier?

The term for a white champagne made from Pinot Noir and/or Meunier is Blanc de Noirs. This style of Champagne is crafted exclusively from dark-skinned grape varieties, specifically black grapes like Pinot Noir and Pinot Meunier. Although it is produced without the skin contact that would typically impart color—hence it being a 'white' Champagne—Blanc de Noirs relies on these varietals for its flavor profile.

Blanc de Blancs, in contrast, refers to Champagne made exclusively from white grapes, specifically Chardonnay, which offers a different set of characteristics, often lighter and more floral. Rosé Champagne includes some skin contact with red grapes, creating a pink hue and infusing the wine with additional fruity flavors. Prosecco is a sparkling wine from the Glera grape, primarily made in Italy, and is distinctively different in style and production method compared to Champagnes.

Thus, knowing the specific grape varieties involved and how they influence the production of the wine helps clarify why Blanc de Noirs is the correct term for the question posed.
