Blanc de Blanc is a term used in the context of sparkling wine, particularly Champagne and other sparkling wines made using the traditional method. The phrase is French and translates to "white of whites" in English. Blanc de Blancs wines are exclusively made from white grapes, and in the case of Champagne, this usually means Chardonnay.

Key points about Blanc de Blancs:

1. **Grapes:** Blanc de Blancs sparkling wines are made using only white grape varieties. In Champagne production, Chardonnay is the primary grape used for Blanc de Blancs, although some producers may also use Pinot Blanc or Pinot Gris.

2. **Region:** While the term itself is French, Blanc de Blancs is not limited to the Champagne region. It is used in other sparkling wine-producing regions around the world where winemakers follow the traditional method of sparkling wine production.

3. **Style:** Blanc de Blancs wines tend to be more delicate and crisp compared to their counterparts made with red grape varieties. Chardonnay, in particular, contributes acidity, finesse, and citrusy or green apple flavors.

4. **Pairing:** Blanc de Blancs sparkling wines are versatile and can pair well with a variety of foods. They are often enjoyed on their own as an aperitif but can also complement seafood, light poultry dishes, and creamy cheeses.

It's important to note that while the term "Blanc de Blancs" specifically refers to white sparkling wines made exclusively from white grapes, the opposite term, "Blanc de Noirs," is used for white sparkling wines made exclusively from black (red) grape varieties, such as Pinot Noir or Pinot Meunier.
