History
Early years
Early settler and pioneer
vineyardist George C. Yount is generally credited as the first to plant grapevines in Napa Valley in 1838.
In 1864, on the marriage of one of his granddaughters to Thomas Rutherford, Yount gave the couple around of land, which Rutherford dedicated to viticulture.
Other pioneers followed in the 1840s and 1850s, by which time vineyards were established in and around
Napa City and up the length of the valley to
Calistoga. Commercial production began in 1858, with
John Patchett selling wine for $2 per gallon.
His wine cellar, built in 1859, narrowly predates that established in 1861 in

Napa Valley's climate and geography are shaped by a unique cooling effect, crucial for premium grape growing. Originating from a cold ocean current from Alaska, this effect involves fog formation and cool air influx from the Pacific, offset by warmer air rising from California's Central Valley. This dynamic results in a climate system where fog and cooler sea air are drawn inland through valleys, create ideal conditions for high-quality viticulture. The region's complexity extends to varying topography, sun exposure, and diverse soils, contributing to a wide array of microclimates or terroirs within a relatively small viticulture area. Napa Valley, despite its linear appearance, is a tapestry of climate influences from the adjacent Vaca and Mayacamas mountain ranges, alongside varied lithologies influencing vineyard substrates.
This geographical diversity, coupled with the Mediterranean climate characterized by hot, dry summers and cool, wet winters, impacts grape growing in the Napa Valley. Rainfall distribution and the daily summer fog, which typically shrouds the valley until mid-morning, vary across the region, affecting grape variety and quality.
However, the potential impacts of climate change pose new challenges: rising global temperatures and possible disruptions to the cooling effect could alter the conditions that have historically favored premium grape growing in Napa Valley.
Enotourism
More than 4.5 million people visit Napa Valley each year, making it a very popular tourist destination in California.
