In 1987, Jim Summers acquired a 28-acre vineyard nestled in Knights Valley, a region located northwest of Calistoga between Mount St. Helena and the Alexander Valley. At the time, the property was predominantly planted with Merlot grapes, established 30 years earlier by Dan Duckhorn, along with some Muscat Canelli. The inaugural vintage of Summers Ranch Reserve Merlot was produced in 1992, yielding 900 cases. Today, the estate also produces Petite Sirah from the Knights Valley vineyard. Known for its warm climate, volcanic soils, and proximity to Napa Valley, Knights Valley has recently garnered increased attention for its Bordeaux varietals.

In 1996, Summers expanded their vineyard holdings by acquiring 25 acres at the intersection of Highway 128 and Tubbs Lane in Napa Valley. This property, now known as Summers Estate Wines, is home to the Villa Andriana Vineyard, named in honor of their daughter. While the estate has been fully revitalized to maximize its potential, the 40-year-old Zinfandel vines are meticulously preserved. The winery and tasting room, surrounded by over 22 acres of Zinfandel, Charbono, and Cabernet Sauvignon vines, strike a perfect balance between pleasure and productivity.

Summers' signature wine is the distinctive Charbono, a varietal believed to be an early Italian adaptation of Charbonneau, a French grape. Some argue it is closely related to the Dolcetto variety, which is commonly grown in northern Italy. The Charbono vine produces large berries that create a deeply colored red wine, known for its rich fruit flavors and low tannin content when subjected to extended skin contact during fermentation.

The Summers Estate, with its scenic vineyard views in Calistoga, California, stands as a testament to the region's rich winemaking heritage.

Pronounced "Duck Soup". This winery offers very limited quantities of unique varietals with a total production of only 1500 cases per year. Duxoup was founded in 1981 by two free-spirited, inquisitive winemakers: Deborah and Andrew Cutter. They built the winery with small production, gentle, gravity flow winemaking in mind. Duxoup wines are silky, fruity, and come from venerable vineyards. The wines express not only terroir, but the highly skilled work of the two owners, both experienced and respected for their independence and consistent quality. The wines are rare, but well worth the effort to find. Duxoup produces a Dolcetto, Gamay Noir, Sangiovese, and Syrah.

Shypoke calls the Calistoga AVA home, with its Estate vineyard nestled in the northwestern corner of the world-famous Napa Valley. The dirt-to-bottle journey began in 1904 when Peter Heitz’s great-grandparents, having immigrated from Alsace, planted roots and established bonded winery #130 for the production of fine wines. Over five generations of grape growers and winemakers, the Heitz family has continued the vision and efforts initiated in 1904. Each wine honors the traditions of a family working together to farm heirloom vines and handcraft the resulting fruit into uniquely elegant and honest wines that reflect their place and vintage.

A family winemaking tradition in the Santa Clara Valley since 1925, Guglielmo Winery is a fourth-generation, family-owned establishment that produces a diverse range of award-winning varietals from approximately 50 acres of California estate vineyards, as well as from other premium wine-growing regions within the state.

Today, Guglielmo Winery (gool-yell-mo) produces over 40,000 cases annually across three labels: Guglielmo Private Reserve, Tre, and its oldest label, Emile’s. Despite its growth, the winery remains committed to its family philosophy of creating natural, high-quality wines to be enjoyed with family and friends, with family members overseeing every phase of the winemaking process.

“Wine is a traditional part of our culture and one of life’s simple pleasures to be shared with family and friends.”
