This is a great little winery along the Foxen Canyon trail. If you want a winery where the owners pour and you can actually talk about winemaking and the whole experience you get it here. Tres Hermanas does not make super jammy Central Coast wines but rather produces numerous wines in a more European style...lower in alcohol, higher in acid and basically more food friendly. I will have to say I enjoy 90% of what they produce. Their Tres Hermanas Cuvee is incredible as is there Nebbiolo, Refosco, Syrah/Sangiovese blend and Muscat Cannelli.

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.

The original riding area now houses prized wines, instead of prize-winning horses. However, Black Stallion Estate Winery carries its heritage forward. The estate’s legacy honors the world-class terroir of Napa Valley, the pioneering spirit of the Silverado Trail, and the Indelicato family’s warm hospitality and generations of wine expertise.

From the late 1800s to the early 1900s, The Silverado Trail was home to cattle and horse ranching. In the 1950s, Richard Tam and Ben Hardister built the Silverado Horseman’s Center covering 32 acres along the southern end of Silverado Trail. The original facility featured an equestrian center with an indoor riding track, 36 horse stalls, and a grandstand for indoor riding events. The property also included an outdoor arena with a grandstand that sat 3,000 people, a half-mile race track, recreation buildings, a private paddock, riding trails, and a stallion breeding center. The center thrived until the 1990s.
