When a champagne or sparkling wine is labeled as blanc de noirs, it means it’s a white wine made from red grapes. In the Champagne region of France, pinot noir and pinot meunier grapes are the red grapes used. Sometimes, winemakers use a combination of the grapes to make a blended blanc de noirs. 

To make a white wine out of red grapes, the grapes are pressed without skin contact. This leaves a clear juice without pigments.
