Napa and Sonoma County Wineries Visited by Extranomical Tours

With over 750 wineries in San Francisco’s wine country, choosing the best locations can be overwhelming. When putting together a tour, we like to select winemakers that offer unique features like gardens or tasting caves, informative presentations, friendly staff, and quality wines not generally available in retail stores.

If you don’t see the wineries you’d like to visit on a tour to Napa and Sonoma Valleys from San Francisco and you have at least 6 people, why not consider a private tour? An experienced travel consultant will help put your custom tour together, handle reservations and all the special details needed to make your day in the wine country perfectly memorable.

Castello di Amorosa

Castello di Amorosa knows how to make a first impression. The authentically styled, 13th-century Tuscan castle winery was constructed using more than 200 containers of European materials and furnishings. This remarkable winery is visited on our Napa Valley Reserve wine tour.

Begun in 1994, a humble building morphed into a castle spanning 121,000 square feet with 107 rooms located in four underground and four above-ground levels. The building has all the elements you’d expect from an authentic Italian castle. A moat with drawbridge, high stone walls, gargoyles, a church, and a fully equipped torture chamber will fascinate on the way to the vaulted wine tasting cellar.

Thankfully, Castello di Amorosa puts the same love and attention into its wines which are elegant, intensely flavored, and well-balanced. The castle winery produces hand-crafted Italian-styled wines, including Cabernet Sauvignon, Merlot, Primitivo and Sangiovese.

Cline Winery

Cline Cellars is a much celebrated family-owned winery in the Sonoma Valley. Known for its ancient vines, the winery specializes in Zinfandel and French Rhone-Style wines.

Cline Cellars is a much celebrated family-owned winery in the Sonoma Valley. Known for its ancient vines, the winery specializes in Zinfandel and French Rhone-Style wines.

The winery was founded in 1982 by Fred and Nancy Cline and moved to its current farm house location in 1991. Fred acquired a love of winemaking from his grandfather Valeriano Jacuzzi, an Italian-born winemaker and namesake of the Jacuzzi Family Vineyards across the street.

Cline Cellars is committed to sustainable growing that maintains the rural beauty of the region. Guided by the talented hand of their winemaker, Charlie Tsegeletos, Cline Cellars seeks complexity, elegance, power, and sense of place in every wine they make.

Etude Wines

Fine wine at this prestigious estate begins in the vineyard where meticulous attention to grapes diminish the need for intervention by the winemaker. That works just fine for Etude wine master, Jon Priest, whose dust-covered boots are proof he spends a lot of time in the field. Recognized as one the most accomplished winemakers in California, Jon has a special touch with Pinot Noir and Cabernet Sauvignon.

In 2005, Etude Cabernet Sauvignon earned a 96-point rating in a 10-year Retrospective Wine Spectator tasting for a wine that “combined dark, rich, potent Cabernet flavors with a sense of elegance and finesse.”

From the beginning, Etude has had sustainability top of mind. Native Oak and Bay trees were retained to protect nearby waterways. Twelve miles of wildlife corridors were incorporated in the planning of the vineyard planting to preserve riparian habitats and the natural migration of wildlife.

Karah Estate Vineyard

This beautiful vineyard estate, situated on scenic acres of rolling hills in the Petaluma Gap is one of the wineries frequented on our popular Sonoma, Russian River, Dry Creek and Alexander Valleys Wine Tasting Tour. Petaluma Gap, designated an American Viticultural Area (AVA) in 2017, is one of the best regions in the word for producing high quality Pinot Noir and Chardonnay.

Each morning the estate experiences heavy fog that lifts around 11am when warm sunshine breaks through, then late afternoon winds are followed by thick evening fog. These wind and fog patterns create long and cool growing seasons that force the Pinot berries to develop thick skins that have a high concentration of phenols which give rise to bold spicy flavor profiles and deep color extraction.

Winemaker, Megan Brodie, explores various winemaking techniques to best exhibit the high-quality fruit that the vineyard produces. As a rule, she uses very minimal intervention, allowing each vintage to tell its own story to the delight of visitors’ senses of sight, taste, touch, smell, and hearing.

Kieu Hoang Winery

In the evening, fog and breezes off nearby San Pablo Bay provide natural cooling in the Carneros AVA. During the day, Kieu Hoang winery’s perfectly situated porch allows guests on our Redwoods and Wine Country Tour to enjoy a glass while looking out over sun-soaked vineyards located in the southernmost grape-growing region in Napa Valley.

Kieu Hoang Winery is an iconic Napa Valley winery founded on land purchased from the famous Mondavi wine family. The winery's owner, Kieu Hoang, a scientist originally from Vietnam, has partnered with winemaker Charles Hendricks to produce several standout varietals.

The winery is particularly well known for its Platinum Label wines made with grapes grown 2000 feet above sea level and in the direct pathway of cool breezes from San Pablo Bay, ideal growing conditions for Chardonnay and Pinot Noir grapes.

Mayo Family Winery

Mayo Family Winery is a small, family-owned and operated winery located in the heart of the Sonoma Valley. Since 1994, Diane and Henry Mayo have specialized in producing small batches of artisanal wines, utilizing hand-picked local grapes. They produce over 20 different single vineyard wines, ranging from Chardonnay, Pinot Noir, and Zinfandel to unique varietals such as Gewurztraminer.

The Mayo Family Winery has always focused on producing wines that capture the best expression of each varietal. We like to visit the Mayo Family Winery on our Redwoods and Wine Country Tour because it is one of the friendliest small wineries in the region and annually produces just 5000 cases or less for sale exclusively in its tasting room and to Wine Club Members.

Jeffrey Mayo is currently President of the winery and guides its operations. Their head winemaker is Michel Berthoud. Mayo Family Winery has won a slew of awards including Gold and Best of Class accolades at the Sonoma County Harvest Fair.

Muscardin Cellars

Muscardini Cellars graces Sonoma Valley’s Monte Terra with its estate grape vines, family home and barrel room. The mission of Muscardini Cellars is to pass the knowledge, tradition and zest for life from more than a century of family experience into wines that artfully capture flavor and spirit.

Over 100 years ago, patriarch Emilio Alchera came to America from Italy. After joining his brothers in San Francisco, he managed a corner grocery store where he sold bulk wines and in his spare time made fine red table wines for the family. His business would eventually become the St. Helena Napa Valley Wine Company.

Guests on Extranomical’s Redwoods and Wine Country Tour consistently rave about the friendly hospitality that flourishes at the Musardini tasting room nestled inside a historic red schoolhouse right in the heart of Sonoma's Valley of the Moon. Enjoy wine by the glass and charcuterie featuring wine-infused salami while having a spontaneous picnic in their patio garden.

Provenance Vineyards

Provenance Vineyards is located in the heart of the Rutherford AVA. The winery owns multiple vineyards up and down the valley including the much coveted and historically significant Hewitt Vineyard, first planted in 1880, resting against the base of the Mayacamas mountains. Each of vineyard brings its own character and sense of place to the wine through the unique soil type, weather patterns, diurnal swings, location and more.

The flagship wine for Provenance is Fortitude – a name that projects courage in the face of obstacles. The first vintage of Fortitude was in 2013 was 100% Cabernet Sauvignon sourced from vineyards in Rutherford, Yountville and Howell Mountain. Provenance also produces several dessert wines including a Port-styled non-vintage Zinfandel made for those who enjoy robust dessert wines that are rich in flavor and alcohol.

Tamber Bey Vineyards

One of the most unique wine experiences in Napa Valley is at Tamber Bey. Its idyllic 22 acres sit in the middle of Sundance Ranch, a world-class equestrian facility. From the tasting courtyard, you’ll be treated to stunning views of Mount St. Helena while you mingle with the Arabian horses of owner Barry Waitte.
