History of Napa Valley
From the Patwin and Wappo villages that first called this valley home, through Spanish exploration and Mexican ranchos, to the founding of an American town.
Long before Napa Valley meant wine, it was a valley of oak woodlands, marshland, and open grassland at the northern edge of San Francisco Bay, home to Patwin and Wappo villages for thousands of years. Spanish explorers passed through in the 1820s, Mexican land grants carved the valley into ranchos in the 1830s and 1840s, and American settlers arrived soon after. What follows is the story of how this small valley went from unmapped territory to an American town, and eventually into the wine region millions now visit -- one chapter at a time, starting well before the first vine was ever planted.
A Valley Long Before Wine
For thousands of years before any European set foot here, Napa Valley was home to the Patwin people, with Wappo communities in the valley's northwestern foothills. Villages were built along the valley floor near reliable water and floodplains, and life followed the seasons: acorns gathered and ground into meal in the fall, deer and waterfowl hunted through the winter, fish taken from the creeks and marshes that once threaded through the valley in spring and summer. The Wappo were especially known for fine basketry, woven tightly enough to hold water, and both groups built homes suited to the climate -- oval, grass-thatched houses in some villages, semi-subterranean earth-covered structures in others. Leadership passed through chiefs chosen to serve for life. Many of the valley's place names today, including Napa itself, are believed to trace back to Patwin village names -- a quiet reminder that the valley had a long history of its own well before anyone called it wine country.
Contact and Upheaval
The first Europeans to explore Napa Valley arrived in 1823, when Francisco Castro and Father Jose Altimura passed through as part of Spain's mission-era expansion north from San Francisco Bay. Real change came a decade later: between 1836 and 1846, the Mexican government granted thirteen ranchos across the valley to settlers, carving what had been open, communally used land into private holdings. The same period brought tragedy to the valley's original inhabitants -- a smallpox epidemic in 1838 killed a large share of the indigenous population, and the valley's Native population had fallen to fewer than 3,000 Wappo and Patwin combined by 1843, according to historical estimates, a loss that shaped everything that came after.
George Yount and the First Vines
The first non-Native settler to make Napa Valley his home was George C. Yount, a trapper and frontiersman who arrived in Mexican California in 1831 and spent his early years working alongside General Mariano Vallejo and his brother, Captain Salvador Vallejo, near Sonoma. That connection paid off in March 1836, when Vallejo helped Yount secure one of the earliest Mexican land grants in Northern California: Rancho Caymus, nearly 12,000 acres spanning the central valley, roughly the area around today's Yountville. Yount wasted little time putting down roots, building a rustic blockhouse and grist mill near the Napa River and, in the years that followed, planting what is believed to be Napa Valley's first vineyard -- decades before wine became the valley's defining industry. He remained a fixture of the valley until his death in 1865, and the town that grew up around his original land grant was later named Yountville in his honor.
A Town Called Napa
American settlement accelerated after the Mexican-American War ended in 1848 and California passed to the United States. That same year, Nathan Coombs, who had arrived in the valley in 1845 and taken part in the Bear Flag Revolt of 1846, laid out the town of Napa on land he had purchased on Rancho Entre Napa. The timing could not have been better: the Gold Rush was pulling tens of thousands of new arrivals into Northern California, and many of them needed a place to farm, trade, and settle once the gold fever passed. Napa's location on a navigable river connected the young town directly to the growing markets of San Francisco Bay, and it quickly became a natural supply point for the whole valley. When California became a state in 1850, Napa County was formed as one of its original twenty-seven counties, with the young town of Napa as its seat -- the administrative foundation the entire valley would grow from.
