Capo Isetta is a third-generation 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 — A fruit-forward, ready-on-release red from the family's northern Sonoma Valley grower partners.

Red Blend — The house "Capo" red, built in the luscious, approachable style winemaker Ryan Kunde favors.

Chardonnay, Sonoma Valley — Sourced from longtime grower families including Sangiacomo and Petroni.

Sauvignon Blanc — Crisp and bright; rounded out by a 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 until 10pm seven days a week, family-friendly, dog-friendly, and equipped with TVs streaming live sports. Winemaker Ryan Kunde sources from outstanding vineyards in the northern part of Sonoma Valley, producing a focused portfolio: a sparkling "Il Vino Frizzante," Sauvignon Blanc from Enzo & Shamrock vineyards, Rosé of Pinot Noir, Chardonnay from Sangiacomo, a five-variety "Cinque Vini" red blend, Pinot Noir, and Cabernet Sauvignon. The Isettas' son Dominic now plays a central role, carrying the family tradition into a fourth generation.

Ryan Kunde
Winemaker

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 sources from prized Sonoma Valley sites farmed by families like the Sangiacomo, Cuneo, and Petroni. 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.

Bill & Marilyn Isetta
Owners

Capo — Italian for “chief” — is the name Bill and Marilyn Isetta chose to honor a family woven into California wine for 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 the Isettas 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.
