California is a winemaking colossus; by itself it is the fourth largest producer in the world. Red wine accounts for 56% of the total by volume, and red grapes 63% of total acres planted. In addition, a number of California red wines are heralded as being among the most prestigious and sought-after wines in the world.

While the state’s incredibly diverse geography, soils and microclimates allow for a wide array of styles, the key factor unifying California red wine is the abundance of sunshine and a long, consistent growing season. This leads to well-developed fruit marked both by impressive ripeness and balancing acidity.

The state’s most famous red wine region, of course, is Napa Valley, where Cabernet Sauvignon reigns as king. But California boasts a wealth of other impressive appellations. The much larger and climatically varied Sonoma County also produces world class California Cabernet, along with wonderful examples of California Pinot Noir and Zinfandel.
