Arturo and Deborah Keller, a Mexico City couple drawn to vintage cars and old-world winemaking, bought 650 acres on the eastern edge of the Petaluma Gap in 1989; daughter Ana now leads. The Legorreta-designed gravity-flow winery sits twenty miles from the Pacific yet catches fog, yielding wines of unusual tension.
Founded by Arturo Keller, an automotive engineer from Mexico City who purchased 650 acres overlooking the Petaluma River in 1989, Keller Estate is the largest winery in the Petaluma Gap. The estate's 90 vineyard acres were planted with nine Pinot Noir clones, four Chardonnay clones, and two Syrah clones — all selected for the wind-driven, fog-influenced site. The winery building, designed by acclaimed Mexican architect Ricardo Legorreta, is a landmark in itself. Today the estate is guided by Ana Keller, Arturo's daughter, whose background in biochemistry informs a rigorous approach to organic and regenerative farming.
El Coro Vineyard Pinot Noir, Petaluma Gap — The flagship single-vineyard Pinot, deep and complex with ripe black cherry.
La Cruz Vineyard Pinot Noir, Petaluma Gap — Savory and plush, from the estate's signature vineyard.
Oro de Plata Chardonnay, Petaluma Gap — Fermented and aged in stainless steel; lean, bright and unoaked.
Rôtie Syrah, Petaluma Gap — A 95-point, refined cool-climate Syrah showing the softer side of the grape.
La Cruz Vineyard Pinot Gris, Petaluma Gap — A crisp, textural estate white.
Founded in 2000 by Arturo and Ana Keller, Keller Estate is the largest winery in the Petaluma Gap, farmed organically and regeneratively, with a winery designed by architects Ricardo and Victor Legorreta. Estate Pinot Noir, Chardonnay and Syrah lead the lineup, alongside Pinot Gris and a sparkling brut.
Arturo and Deborah Keller, a Mexico City couple with a love of vintage cars and old-world winemaking, bought 650 acres on the eastern edge of the Petaluma Gap in 1989 and planted the first Chardonnay vines that same year with the guidance of viticulturist Ted Lemon. The estate label followed in 2000, housed in a striking minimalist winery designed by Mexican architects Victor and Ricardo Legorreta and built for gravity-flow winemaking. The vineyard sits twenty miles from the Pacific but still catches the coastal fog that defines the Gap, and the cool, windy site translates into wines with unusual acidity and tension — particularly the flagship La Cruz Vineyard Chardonnay and Pinot Noir. Farming is organic and regenerative across the property, with 86 acres of vines spread between nine clones of Pinot Noir, four of Chardonnay, and two of Syrah. Visits are by appointment, with seated estate tastings on the terrace overlooking the olive grove and Mount Tamalpais, or a longer Tour and Tasting that includes the barrel cave.
Ana Keller leads the winegrowing and winemaking at Keller Estate as second-generation vintner and Estate Director, a role she pairs with a biochemist's command of what happens inside the barrel. Her family — of Mexican heritage — founded the estate around 2000 and was instrumental in establishing the Petaluma Gap AVA in 2017, where persistent wind and fog shape the estate's cool-climate Pinot Noir, Chardonnay, and Syrah from organically and regeneratively farmed vineyards. In 2025 the estate brought on acclaimed winemaker Theresa Heredia — formerly of Freestone and Gary Farrell — as consulting winemaker, deepening a decades-long friendship and a shared, detail-driven approach to capturing the Gap's distinctive character.
Arturo Keller founded Keller Estate with his wife Deborah, transforming a Petaluma hillside into one of the Petaluma Gap’s benchmark estates. Born and raised in Mexico City to a family of Swiss descent, he built a successful auto-seat manufacturing business and was a passionate collector of vintage automobiles. In the early 1980s the Kellers bought the 600-acre property; they planted the La Cruz Vineyard’s first Chardonnay in 1989 and founded their Legorreta-designed, gravity-flow winery in 2000. He invited his daughter Ana to lead the winemaking, and his vision and love of the land remain the estate’s guiding legacy.
