Napa Valley is a Viticultural Area located in Napa County, a county located north of San Pablo Bay in the northern portion of California's Wine Country. The combination of Mediterranean climate, geography and geology of the region are favourable to growing quality wine grapes. John Patchett was the one who established the Napa Valley's first commercial vineyard in 1858.

Here is the list of top 10 wineries of Napa Valley

Their Chardonnay plantings are on their Estate in the Oak Knoll District of Napa Valley.

Trinchero Napa Valley

Trinchero Winery consists of 6 vineyards:

Mary's Vineyard

This vineyard was originally planted in the year 1990 which nestled at the northern end of Napa Valley in the Calistoga appellation, this vineyard’s ample sun exposure and moderately fertile soils. It produces Sauvignon Blanc with ripe, exotic flavours and crisp, palate-cleansing acidity.

Mario`s Vineyard

This vineyard was originally planted in the year 1997 and named for their pioneering founder Mario Trinchero, this rare jewel of a site surrounds their winery in St. Helena, along with a narrow stretch of the valley floor formed by river-based soil erosion. A northwest exposure, coupled with a mix of gravel, loam and alluvial soils, makes Mario’s Vineyard ideally suited for opulent Cabernet Sauvignon with impressive structure and velvety tannins.

St. Helena - Napa Valley

This vineyard was originally planted in the year 1989 and with its nostalgic nod to their family’s roots in New York City. Their Central Park West Vineyard rests on the valley floor at the southern end of the St. Helena appellation. This 22-acre site, with its ample sunshine and deep loamy and alluvial soils, is perfectly suited for growing classic red Bordeaux varieties.

Cloud`s Nest Vineyard

This vineyard was originally planted in the year 1997 and soaring high above the valley floor to 1,500 feet in the Mt. Veeder appellation, their 13-acre Cloud’s Nest Vineyard is incredibly steep with gravelly soil. A cool eastern exposure gives the grapes more time on the vine to develop the region’s signature bold, luscious flavours.

Haystack Vineyard

This vineyard was originally planted in the year 1997. The Atlas Peak region, Napa Valley’s highest appellation, is home to their Haystack Vineyard, an extremely rocky site, where struggling vines create small, intensely concentrated berry clusters

Vera`s Vineyard

This vineyard was originally planted in the year 1999. A confluence of morning fog, abundant afternoon sunshine and breezes from nearby San Pablo Bay allows the grapes at Vera’s Vineyard to ripen gradually and evenly, resulting in deeply concentrated flavours.

Artesa Estate Vineyards and Wineries

In the 1980s, the historic Spanish winemaking family Codorníu Raventós began to acquire and develop vineyard land in the Carneros region of Napa Valley. It was opened in 1991 as Codorníu Napa, a sparkling wine house, the winery ultimately transitioned to producing still wines as successive vintages revealed the quality and potential of the family’s vineyard holdings. The winery was renamed Artesa – Catalan for “handcrafted” – in 1997 and has since become a leading producer of artisan wines from the varietals for which Carneros and Napa Valley are best known: Chardonnay, Pinot Noir and Cabernet Sauvignon.

Pina Napa Valley

Pina Napa Valley family’s history of growing grapes and making wine stretches back to their great-great-great-grandfather, Moses Stice, who settled in the Napa Valley in the 1850s. Their grandson, Lafayette Stice, their great-grandfather, learned winemaking at the Harris Winery (now Martin Estates) and then went on to make wine at Brun and Chaix Winery (now Ladera).

Silver Oak

The Silver Oak property was originally deeded in 1877 to Cyrus Alexander; namesake of the Alexander Valley, who first established the land as one of the finest vineyard sites in Sonoma County. Today, the vineyard is planted to 75 acres of Cabernet Sauvignon and will form the future backbone for their Alexander Valley Cabernet Sauvignon.

Falcor Napa Valley

For the first few years, Falcor had to limit its production to an exceptional Chardonnay that served as its calling card to the wine industry. Then, the 1999 Napa Valley Chardonnay became one of the nation’s top scoring Chardonnays, scoring 93 Points in the Wine Spectator. Falcor was officially on the map by 2004 and was producing eight different varietals.  Focusing on high quality, small lot productions, they currently produce around 15 diverse, internationally award-winning varietals.

Tedeschi Family Winery

Eugene Tedeschi purchased this Tedeschi Family Winery in the 1950s on the outskirts of Calistoga. When he purchased this vineyard, there were acres of various fruit trees, including apples and persimmons. To savour the beauty, he planted his grapevines between the trees, planting rows of grapes intertwined with the diverse fruit trees. He planted many varietals of grapes, including Cabernet Sauvignon, Zinfandel, and Petite Sirah. Emil Tedeschi is managing the same property now with his three children. He has dedicated 1 acre of the estate to Cabernet Sauvignon.

The Hess Collection

An unparalleled passion and curiosity combined with a pioneering spirit that stretches over five generations of the Hess family since 1844, and on into the next generation of family leadership appointed by Founder Donald Hess. Each of the family’s wineries – in California, Argentina, and South Africa – produce outstanding, highly acclaimed wines that stand alongside the very best. Today, Hess Family Wine Estates is recognized as one of the premier family-owned and family-led companies in the world of wine.
