Armand de Brignac Demi-SecAces of Spades Champagne. The Armand de Brignac Demi Sec was once a curiosity shared only with visitors to the maison in Chigny les Roses, France. The Demi Sec was created to provide a sweeter elaboration that pairs with the most exotic of foods. Notes of English candy, grapefruit, compote fruits, caramel, quince and brioche. The palate is abundant with crystalized citrus fruits, honey and hints of blackberries. An ideal pairing with foie gras,
