Tasting notes: Silky and dense, this dark red is laden with aromas of boysenberry, crème de cassis, and soft vanilla. Its broad palate mingles flavors of dark berry, sandalwood, and caramel. Worth knowing: Mary Rocca’s circuitous career demonstrates that, contrary to Thomas Wolfe’s observation, you can go home again. In 1989, Rocca left her dental practice in Rochester, Minn., where her husband, physician Eric Grigsby, worked at the Mayo Clinic. She returned to her roots when she subsequently moved her family to Napa Valley: She had been raised across the county line, in Sonoma, where her family grew most of their own produce. Intent on returning to the agricultural values of her childhood, she began to search for vineyard property. In 1999, she purchased a prized parcel in Yountville (now the Grigsby Vineyard), and a year later she bought the Collinetta Vineyard in Coombsville.
