the rock star red is a 50/50 cabernet/syrah blend. the two grapes work well together in many wines, but here they seem a bit at odds. the cabernet carries some green, herbal, pickle barrel flavors; the syrah brings in pepper and spice, but neither has the ripeness to flesh out the wine sufficiently. there are flavors of plum and cooked cherry, then it hits some chewy tannins and stops short.
