What to Expect
Expect a dessert-style, port-like, or sherry-inspired Grenache wine from Arizona, crafted with flavors that might remind you of its French and Spanish roots but infused with unique Arizona terroir. Whether enjoyed on its own as a dessert wine or used in cooking, this versatile grape offers the depth and complexity one would expect from a well-crafted GSM blend.
