What to Expect
RANCHO CAPISTRANO WINERY's Grenache, Syrah, and Mourvèdre come together in a blend that showcases the rich potential of these grapes. Origin unknown, this wine offers an intriguing glimpse into the winery’s terroir through its varietal composition alone. With flavors ranging from savory and peppery to rich and full-bodied, expect a nuanced experience that reflects the versatility of Syrah, whether you prefer it in the restrained style of French Rhône or the more fruit-forward approach of Australian Shiraz.
