What to Expect
The CALCAREOUS dessert/wine is crafted from the robust Grenache grape, a varietal native to Spain and widely grown in France's Rhône region and Spain’s Rioja and Priorat. Originating from California, this wine offers a rich, full-bodied flavor profile that can be enjoyed as a dessert or cooking wine, complemented by its GSM blend characteristics.
