The Heringer Family has always believed in hard work, innovation and resourcefulness. We have always utilized whatever land, crop, or agricultural business opportunities were available to us such that our presence in the industry, the integrity of our family name, and the continuity of the family farm were assured for future generations.This has been accomplished through the generations while maintaining relationships of integrity with venders, customers, employees, and family members.

Mayo Family Winery produces small lots of single-vineyard wines under the premise that the world's most interesting and highest quality wines must come from a single-vineyard source that can be expressed in the wines' aroma, taste and texture. Founded in 1993, the winery has two winemaking facilities in Glen Ellen, California, each fitted and equipped to produce particular types of wines. Mayo Family wines are only sold online or in their tasting room attached to the winery in the town of Glen Ellen and their two other tasting rooms in Sonoma Valley.

Dry Creek Vineyard is known for their Chenin Blanc, Chardonnay, Merlot, Cabernet Sauvignon, Meritage and, starting with the 1997 vintage, Endeavour Cabernet. Dry Creek Vineyard owns over 185 acres of vineyard land, primarily in the Dry Creek and the Russian River Valleys.

The tasting room is reminiscent of some of the small wineries in the Provencal French countryside, featuring a kitchen complete with a wood-burning oven and two stone barrel-aging caves built into the hillside. The gorgeous courtyards and picnic grounds provide the perfect place to experience the wines. The Villa at Sunstone now serves as an extension of the Sunstone Winery lifestyle by providing a culinary center to entertain guests for weddings, winemaker dinners and private culinary retreats.
