The Mayo family has made single-vineyard wines from across Sonoma County since 1993, a portfolio ranging from Chardonnay and Zinfandel into harder-to-find Carignane, Petite Sirah, and Alicante Bouschet. The Glen Ellen tasting room is dog- and family-friendly; the Reserve Room in Kenwood offers a seven-course food pairing.
Mayo Family Winery was founded in 1993 by Henry and Diane Mayo and is now run by their son Jeffrey alongside winemaker Michel Berthoud. The family's approach is simple and unfashionable: small lots, single vineyards, and a portfolio that goes broader than most. In any given year, Mayo produces over 25 wines from more than 15 varietals — Chardonnay, Pinot Noir, and Zinfandel anchor the program, but the lineup also includes Pinot Meunier, Grenache, Alicante Bouschet, Carignane, Petite Sirah, Sangiovese, late-harvest dessert wines, and Zinfandel-based ports. Annual production runs around 5,000 cases or less, sold almost entirely through the tasting rooms and wine club.
Ricci Vineyard Old-Vine Zinfandel — A single-vineyard Zinfandel that anchors Mayo's reputation for small-lot, site-specific reds.
Single-Vineyard Chardonnay — One of the house flagships, from select Sonoma and Napa sites.
Pinot Noir — Cool-climate fruit in Mayo's hand-crafted, single-vineyard style.
Alicante Bouschet — A deeply colored, rarely bottled heritage red from the winery's adventurous lineup.
Zinfandel Port — A fortified dessert Zinfandel; Mayo makes 20-plus wines a year across 15-plus varietals.
The main tasting room sits on Arnold Drive in Glen Ellen, open daily 10:30 AM – 6:30 PM, with a courtyard that welcomes families, dogs, and BYO picnics. The Mayo Family Reserve Room in nearby Kenwood is the more ambitious experience: a seven-course pairing menu by chef Sam Frumpkin matches seven Reserve wines from winemaker Berthoud — an unhurried, vine-to-table journey that's been a quiet local favorite for two decades. Wines are available only on-site and through the wine club, never in stores, which keeps the relationship between maker and drinker direct. A genuine independent family operation in a valley where those grow rarer every year.
Michel 'Mike' Berthoud was born and raised in Sonoma Valley and began making wine with his Swiss-born father at age eight; the family still operates the small Berthoud Winery. He earned a degree in fermentation science from Fresno State and learned the craft in the cellar under Richard Arrowood at Chateau St. Jean, then spent some fifteen years as winemaker at Arrowood Winery before joining Mayo Family Winery just ahead of the 2004 harvest. He oversees all winemaking for the Mayos' single-vineyard program — built around Zinfandel and a wide range of Sonoma Valley reds and whites — working closely with the winery's many grower partners. With more than thirty harvests behind him, Berthoud treats winemaking as an artisan craft that begins in the vineyard, a sensibility shaped by both his European upbringing and his Sonoma mentors.
Jeffrey Mayo turned a family side project into a Sonoma single-vineyard specialist. His parents, real-estate broker Henry Mayo and his wife, Diane, planted Chardonnay on their Glen Ellen hillside in 1990 and bottled their first 200 cases in 1993; when demand outgrew Henry’s day job, they called Jeffrey. He agreed on one condition — a year in France studying wine first. A former homebuilding-company executive, Jeffrey returned to steer the winery toward small-lot, single-vineyard bottlings drawn from prized sites across Sonoma and beyond, the strategy that defines Mayo Family today.
