In 2000 a group of Mendocino County Winemakers joined together and decided to create an ultra-premium wine blend that would showcase the heritage varietal of Mendocino County, Zinfandel. Every Coro wine is a signature blend…individually crafted in Mendocino County from 100 percent Mendocino County grapes, in strict accordance with the Consortium Mendocino Bylaws. The wines must pass a review by a panel of winemakers in four blind tastings before the wine is accepted and certified to carry the Coro Mendocino label.
