Napa is warmer in the summer than Sonoma County to the west or Santa Barbara County, a wine-producing county in southern California. Thus, the Napa wineries favor varietals such as Cabernet Sauvignon, while Pinot Noir and Chardonnay are more the specialty of Sonoma wineries and Santa Barbara wineries At the north end of Napa County, in the Mayacamas Mountains, lies Mount Saint Helena, the Bay Area's second tallest peak at 4,344 feet (1,323 m) and home to Robert Louis Stevenson State Park. At the west side of the Napa Valley is Hood Mountain, elevation 2,750 feet (838 m).
In 1776 a fort was erected by the Spanish Governor, Felipe de Neve a short distance northwest of Napa, on an elevated plateau. Russians from Fort Ross in neighboring Sonoma County grazed cattle and sheep in Napa County in the early 1800s and in 1841 a survey party from the fort placed a plaque on the summit of Mount Saint Helena.
Don Francis Castro and Father Jose Altimura were the first Europeans to explore the Napa Valley in 1823. When the first white settlers arrived in the early 1830s, there were six tribes in the valley speaking different dialects and they were often at war with each other. The Mayacomos tribe lived in the area where Calistoga was founded. The Callajomans were in the area near where the town of St. Helena now stands. Further south, the Kymus dwelt in the middle part of the valley. The Napa and Ulcus tribes occupied part of the area where the City of Napa now exists while the Soscol tribe occupied the portion that now makes up the southern end of the valley. Many of the native peoples died during a small-pox epidemic in 1838. Settlers also killed several over claims of cattle theft.
George Calvert Yount was a noteworthy early settler in Napa County and is believed to be the first Anglo-saxon resident in the county. When Yount first arrived there in 1831, he made his living hunting and trapping. In 1836 Yount obtained a grant from the Mexican government for the Caymus rancho where he built what is said to be the first log house in California. Soon afterward, he built a sawmill and grain mill and was the first person to plant a vineyard in the county. Following Yount's death in 1865 at age 71, the town of Yountville was named in his honor.
Colonel Joseph B. Chiles a guide for one of the earliest immigrant trains to California, was granted Rancho Catacula in 1844. The Town of Napa was founded by Nathan Coombs in 1847.
Following the event of the Mexican–American War, Bear Flag Revolt in 1846 and the Mexican Cession in 1848, settlers were granted deeds from the original ranchos during the 1850s through 1870s. To this day, a number of streets and landmarks around the valley reflect the names of these districts and original grantees.
Napa County was formed and became one of the original California counties when the state became part of the United States in 1849.
The county's population began to swell in mid century as pioneers, prospectors and entrepreneurs moved in and set up residence. During this period, settlers primarily raised cattle, farmed grain and fruit crops. Mineral mining also played a role in the economics of the county. While gold was being prospected in other areas of the state in the 1850s, Napa County became a center for silver and quick silver mining.
Two entrepreneurs who made their mark on Napa County during the mid 1800s were Edward Turner Bale and Samuel Brannan. Following his marriage to General Vallejo’s niece Maria Guadalupe Soberanes, Bale became a citizen of Mexico and was granted the Carne Humana Rancho in the northern end of the valley. Bale completed building the Bale Grist Mill a few miles north of St. Helena in 1846. Brannan purchased land in the northern end of the valley at the foot of Mount Saint Helena and founded Calistoga. He began developing it as a resort town taking advantage of or the area’s numerous mineral hot springs. He also founded the Napa Valley Railroad Company in 1864 to bring tourists to Calistoga from San Francisco ferry boats that docked in Vallejo. Brannan’s railroad venture failed and was sold at a foreclosure sale in 1869. The railroad eventually came under ownership of Southern Pacific Railroad late in the 19th century.
Descendents of George Yount and Edward Bale played key roles in the early development of Napa County's wine industry. Bale's daughter Caroline married winemaker Charles Krug in 1860. Bale provided a dowry that included 20 acres (80,937 m²) of land north of St. Helena, California. Krug planted a vineyard and established the valley's first commercial winery on this land. Yount's daughter Elizabeth married Thomas Rutherford in 1864. The couple received 1040 acres (4.209 km²) of land as a wedding present from Elizabeth's father in the area of the valley now known as Rutherford. Rutherford established himself as a serious grower and producer of fine wines in the following years.
In 1866 John Lawley established a toll road from Calistoga over Mount Saint Helena to Lake County.
Robert Louis Stevenson's book The Silverado Squatters provides a snapshot of life and insight into some of the characters that lived around the valley during the later part of the 19th century. Stevenson, accompanied by his new bride Fanny Vandegrift and her 12 year old son from a previous marriage, Lloyd Osbourne, spent the late spring and early summer of 1880 honeymooning in an abandoned bunk house at a played out mine near the summit of Mount St. Helena. In the book, Stevenson's descriptive writing style documented his ventures in the area and profiled several of the early pioneers who played a role in shaping the region's commerce and society.
The Veterans Home was established in Yountville in 1884 by the San Francisco chapter of the Grand Army of the Republic. The State of California assumed administration of the Home in 1897.
Stevenson's book also brought attention to the various spas and hot springs in the county. From Calistoga to Æetna Springs in Pope Valley to Soda Springs Resort a few miles east of Napa, tourists of the late 1800s and early 1900s made the county their destination much the same as modern day tourists. The resorts became very popular with San Franciscans anxious to escape the infamously cold and foggy weather that often plagues the city to enjoy the warmer climate that Napa County offered.
By the end of the 20th century's first decade farmers had planted over 500,000 fruit and nut trees in the county. This helped to soften the blows to the agricultural economy caused by the phylloxera infestation in the county's vineyards and upcoming prohibition that crippled the wine industry.
Napa Valley is widely considered one of the top AVAs in California, and all of the United States with a history dating back to the early nineteenth century. By the end of the nineteenth century there were more than one hundred and forty wineries in the area. Of those original wineries several still exist in the valley today including Charles Krug Winery, Shramsburg, Chateau Montelena and Beringer. Viticulture in Napa suffered a setback when prohibition was enacted across the country in 1920. Furthering the damage was an infestation of the phylloxera root louse which killed many of the vines through the valley. These two events caused many wineries to shut down and stalled the growth of the wine industry in Napa County for years. Following the Second World War, the wine industry in Napa began to thrive again.
In 1965, Napa Valley icon Robert Mondavi broke away from his family's Charles Krug estate to found his own. This was the first new large scale winery to be established in the valley since before prohibition. Following the establishment of the Mondavi estate, the number of wineries in the valley continued to grow, as did the region's reputation.
In addition to large scale wineries, Napa Valley's boutique wineries produce some of the world's best wines. The producers of these wines include but are not limited to: Araujo, Bryant Family, Colgin Cellars, Dalla Valle Maya, Diamond Creek, Dominus Estate, Duckhorn Vineyards, Dunn Howell Mountain, Grace Family, Harlan, Husic, Kistler, Jericho Canyon Vineyards, Marcassin, Screaming Eagle, Shafer Hillside Select, Sine Qua Non, Spencer-Roloson Winery and Vineyard 29.
Today Napa Valley features more than three hundred wineries and grows many different grape varieties including Cabernet Sauvignon, Chardonnay, Merlot, Zinfandel, and other popular varietals. Napa Valley is visited by as many as five million people each year.
The county has resisted encroachment on the preserve since it was created with voters reaffirming their desire keep it intact on several occasions. In 1990 voters passed Measure J adopting an initiative freezing all county zoning changes until the year 2020 unless there is a ⅔ majority vote to adopt such changes. Measure J was reaffirmed by a 5-2 vote of the California Supreme Court in 1995 in the case of Devita v. County of Napa .
The Land Trust of Napa County was founded in 1976 by a group of local citizens with a mission to protect the natural diversity, scenic open space and agricultural vitality of the county. The trust acquires conservation easements, facilitates land transfers to local, state and federal agencies along with accepting outright donations of land within and outside the boundary of the agricultural preserve. The trust now covers over 50,000 acres (202.34 km²) .
While establishment of the agricultural preserve and the land trust has slowed residential development in much of the county, residential growth within the incorporated cities has continued at a moderate pace. Several substantial homes have been built on the hills surrounding the valley in areas not covered by the preserve or the land trust. A large portion of the land south of the City of Napa remained undeveloped for many decades until the 1980s. Several wine bottling facilities and wine storage warehouses now stand on what was once vacant land. A number of light industries have also sprung up in this region as new business parks have been built. The growth of American Canyon, Napa County’s southernmost and newest city; incorporated in 1992 has prompted the establishment of several new retail outlets in the southern end of the county in recent years. American Canyon has also established a green belt preserve of over 1000 acres (4.047 km²) on the western and eastern sides of the city.
