Joseph Phelps Vineyards is a family-owned winery based in St. Helena. It was founded in 1973 when Joseph Phelps, a building contractor from Colorado, arrived in Napa Valley to build wineries. He soon decided to make his own wine and purchased a former cattle ranch near St. Helena. Phelps Vineyards now owns or leases 560 acres of vineyards in Napa Valley and the Sonoma Coast. The estate owns choice properties in St. Helena, Stags Leap, Oakville, Rutherford, South Napa Valley and Oak Knoll. Phelps is best known for Insignia, its flagship Napa Valley blend of red Bordeaux varieties first produced in 1974. Awarded Wine Spectator’s “Wine of the Year” in 2005, Insignia is widely regarded as a qualitative benchmark for California winemaking. Besides Cabernet Sauvignon and small amounts of Petit Verdot, Merlot and Malbec, Phelps also grows Chardonnay, Syrah, Pinot Noir, Sauvignon Blanc and Scheurebe. The estate produces 50,000 cases annually from Napa Valley and an additional 15,000 cases from the Sonoma Coast.
Paso Robles AVA is midway between San Francisco and Los Angeles, and it is considered one of the West Coast’s most exciting winemaking regions. With its hot, sometimes searingly dry and sunny weather, it is especially good country for growing warm climate grapes such as Syrah, Grenache and Mourvedre. Because many Paso Robles wineries have been successful with blending these grapes into Rhone Valley-style wines, it is known as the Rhone zone of California. The AVA was created in 1983 and there are 32,000 vineyard acres. In late 2014 the AVA was divided into 11 smaller sub-appellations, so starting with 2015 vintages labeling will become more specific on Paso Robles wines, which will now also list sub-appellations. Located in San Luis Obispo County, Paso Robles, the town and its surrounding area, was traditionally a farming and ranching region. But from a few dozen wineries in the early 1990s to more than 200 today, the area is quickly becoming known for wine and risk-taking winemakers.
