The Napa Valley
is an American wine region located in Napa County, California. It is considered to be one of the top wine producing regions in the United States, with a wine heritage dating back to the 19th century. The Napa Valley producers came through the Phylloxera crisis at the turn of the last century, and U.S. Prohibition from 1920 to 1933, and now produce highly regarded wines.
The Napa Valley has a Mediterranean climate with oceanic influences, along with a geology and landscape conducive to quality viticulture.
The Valley has 340 different wine growing zones planted with several varietals, including Cabernet Sauvignon, Chardonnay, Pinot Noir, Merlot and Zinfandel. Most estates produce a Napa Valley wine which is typical of the Valley, and some choose to mix or blend their wines, using wines sourced from the Valley and the surrounding hills. U.S. law allows the name of the grape variety to appear a Napa Valley wine label if the variety in question makes up at least 75% of the blend. Therefore, many Napa Valley wines labeled as Cabernet Sauvignon often contain some Merlot, Cabernet Franc, Durif or Syrah. Similarly, a wine can be labeled “Napa Valley” if at least 85% of the grapes come from the wine region of the same name, allowing growers to source from other regions, often at lower prices, to create their wine blends.
