The spot where Highway 29 meets Rutherford Road in the tiny community of Rutherford may well be the most significant wine-related intersection in the United States. With its singular microclimate and soil, Rutherford is an important viticultural center, with more big-name wineries than you can shake a corkscrew at, including Beaulieu, Inglenook, Mumm Napa, and St. Supéry.
Cabernet Sauvignon is king here. The soil is ideal for those vines, and since this part of the valley gets plenty of sun, the grapes develop intense flavors. Legendary winemaker André Tchelistcheff's famous claim that "it takes Rutherford dust to grow great Cabernet" is quoted by just about every winery in the area that produces the stuff. That "Rutherford dust" varies from one part of the region to another, but the soils here are primarily gravel, sand, and loam, a well-drained home for Cabernet Sauvignon grapes, which don't like to get their feet wet.
