Based on everything I read, this Cotes du Rhone is 100% Grenache. Smelling and tasting it, I would swear that it has a fairly high percentage of Syrah.
Deep and dark. Smells tannic and a bit backward. Mostly black fruits--blueberries, blackberries, plums. On the palate, though, reasonably deep fruit flavors come forth. Again, plums and berries. Very little of the red berry, spice and pepper that I expect from 100% Grenache, but, nevertheless, an enjoyable wine. I would buy more.
