Napa Valley is widely considered one of the top American Viticultural Areas 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.
Robert Mondavi Winery, Napa
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.
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.
