This dessert wine from VINES ON THE MARYCREST is a delightful blend of Grenache, Syrah, and Mourvèdre grapes grown in California. With its rich and full-bodied character, it pairs beautifully with desserts or can be enjoyed on its own as an elegant aperitif. Whether you prefer a more savory flavor profile reminiscent of Rhône-style wines or something more concentrated akin to Australian Shiraz, this wine offers versatility that caters to both traditional and modern tastes.
