A family business with deep California roots: Bill Isetta's grandfather was a 1920s cooper, and both his and Marilyn's fathers worked at Christian Brothers. Bill, Marilyn, and son Dominic work with partner growers such as the Sangiacomo, Cuneo, and Kunde families, with Ryan Kunde as winemaker. The Sonoma Plaza tasting room is open late and family-friendly.















Capo Isetta is a Sonoma wine family whose roots in California winemaking go back nearly a century. Bill Isetta's grandfather Giacomo "Giac" Isetta was a skilled cooper crafting wine barrels in the 1920s. Bill's father Andy Isetta worked at the famed Christian Brothers Winery alongside Brother Timothy, eventually running operations at Mont LaSalle before founding Old Pioneer Wine Company of San Francisco with his father. Marilyn Isetta's father Ray Hulmer retired in 1978 after 35 years as Treasurer and Controller of Christian Brothers Wines and Brandy. Bill and Marilyn met as children when their families crossed paths at Mont LaSalle, and Capo Isetta, capo meaning "chief" in Italian, is the realization of that shared family heritage.
Sonoma Coast Pinot Noir: bright cherry, cranberry, and rose petal over a silky palate with fine tannins; aged 18 months in French oak.
Cabernet Sauvignon, Sonoma Valley: the "Cuneo" bottling, a fruit-forward, ready-on-release red named for grower partner Cuneo.
Red Blend, Sonoma Valley: the house red blend, built in the luscious, approachable style winemaker Ryan Kunde favors.
Chardonnay, Carneros: a Carneros bottling, joined on the list by a value-priced California Chardonnay.
Sauvignon Blanc, Russian River Valley: crisp and bright; rounded out by a Sonoma Coast Rosé and the Il Vino Frizzante sparkling.
The tasting room sits at 412 First Street East on the Sonoma Plaza and is unusual among Sonoma's wineries: open late seven days a week, family-friendly, dog-friendly, and equipped with TVs streaming live sports. Winemaker Ryan Kunde keeps production limited, and the list reaches past the core bottlings to a sparkling red, Scintillante Rosso, a Moon Mountain Sangiovese, and a value-priced California Cabernet Sauvignon for everyday pouring. Tastings can be reserved online through CellarPass.

A fifth-generation member of the Kunde winegrowing family, Ryan Kunde was born in the town of Sonoma, where a connection to the land runs deep. He earned a first degree at Arizona State, selling wine for Gallo along the way, before returning for a B.S. in Viticulture and Enology at UC Davis in 2011, then founding his own label, DRNK Wines, with his wife Katie in 2012. He brings that same precision to Capo Isetta, where he works with fruit from partner growers such as the Sangiacomo, Cuneo, and Kunde families. His philosophy pairs an inherited feel for the vineyard with modern data and small-lot fermentation, aiming for wines that are fruit-forward, layered, and ready to enjoy on release.

Capo, Italian for “chief”, is the name Bill and Marilyn Isetta chose to honor a family woven into California wine for nearly a century. Bill’s grandfather, Giacomo “Giac” Isetta, shaped wine barrels as a cooper in the 1920s; his father, Andy, worked at Christian Brothers before launching the Old Pioneer Wine Company. Marilyn’s father, Ray Hulmer, spent 35 years at Christian Brothers, where the two families first met. Today Bill, Marilyn, and their son Dominic, proprietors together, pour their handcrafted, small-lot wines from a warm, open-late tasting room on the Sonoma Plaza, a gathering place built, as Bill puts it, for friends old and new.
