non-vintage sparkling wine from France’s Loire Valley. This region is best known for the white grape Chenin Blanc. Caves de Grenelle, which produces this cuvee, grows Chenin Blanc, Chardonnay and Cabernet Franc. Since this wine is called “Blanc de Blancs,” which indicates an all-white-grape blend, this must be made from Chenin Blanc and Chardonnay. The winery has a long tradition, founded in 1859, and is known for producing fine Cremant de Loire (sparkling wines from the Loire region).
