2009 Ravenswood Dickerson Vineyard Zinfandel

Ravenswood was founded in 1976 in Sonoma Valley by Joel Peterson. Peterson is a microbiologist by training, but while doing immunology research in San Francisco in the early 1970s he began dabbling in winemaking. Because of his success with Zinfandel, he quickly became known as the godfather of Zinfandel, and single vineyard Zinfandels continue to be the estate’s flagship wines. Ravenswood owns about 15 acres of vineyards but acquires most of its grapes from a network of more than 100 northern California growers. The estate also makes Chardonnay, Merlot, Cabernet Sauvignon and various blends.

Napa Valley AVA is the most famous winemaking region in the United States and one of the most prestigious in the world. With nearly 43,000 acres of vineyards and more than 300 wineries, it is the heart of fine wine production in the United States. Winemaking started in Napa in 1838 when George C. Yount planted grapes and began producing wine commercially. Other winemaking pioneers followed in the late 19th century, including the founders of Charles Krug, Schramsberg, Inglenook and Beaulieu Vineyards. An infestation of phylloxera, an insect that attacks vine roots, and the onset of Prohibition nearly wiped out the nascent Napa wine industry in the early 20th century. But by the late 1950s and early 1960s Robert Mondavi and other visionaries were producing quality wines easily distinguishable from the mass-produced jug wines made in California’s Central Valley. Napa Valley’s AVA was established in 1983, and today there are 16 sub-appellations within the Napa Valley AVA. Many grapes grow well in Napa’s Mediterranean climate, but the region is best known for Cabernet Sauvignon. Chardonnay is also very successfully cultivated, and about 30% of the AVA’s acreage is planted to white grapes, with the majority of those grapes being Chardonnay,

Zinfandel is a black-skinned grape, but 85% of the wine produced is made into a rosy “White Zinfandel.” Red Zin is far more complex and bold, while still being light-bodied. It grows in popularity as winemakers continue to experiment with new styles and blends.
