The initials stand for Grenache-Syrah-Mourvedre-Cinsault (the blend is two-thirds Grenache). A full, flowery bouquet sends up a potpourri of blossoms, citrus and coffee scents. The smorgasbord continues with a mouthful of concentrated plum, prune and cherry fruit. Careful barrel management adds pretty spices to the finish, with just a touch of moist earth in the tannins. A powerful, lingering delight. ——P.G.(11/1/2008)—— 93
