2009 Trefethen Halo

Trefethen Family Vineyards is in the Oak Knoll District of Napa Valley. It was founded by John and Janet Trefethen in 1973. John’s parents, Eugene and Catherine, had retired to Napa Valley in 1968 and had purchased several small farms and a rundown winery. Eugene had been an executive with Kaiser Industries and his retirement plan was to sell grapes. John, however, started making wine as a college student and in 1973 he and his wife produced a debut commercial vintage. The 560-acre estate is known for its Chardonnay, though it also produces Cabernet Sauvignon, Pinot Noir, Riesling, Viognier, Cabernet Franc, and 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,
