A blend of 52% Grenache, 41% Syrah and 7% Mourvèdre, the 2015 GSM reveals a brooding nose of ripe black fruit, smoke and asphalt. On the palate, it's full-bodied, rich and chewy, with firm structuring tannins and a ripe, baked core of fruit. It's a rustic, flavorful red that lacks a bit of energy and succulence to score higher.
