Napa Valley AVA
- the best-known of the US’s wine-producing areas, situated between the Vaca and the Mayacamas Ranges in northern California and containing over 250 wineries. Around 65 per cent of the white grapes planted are Chardonnay, but Sauvignon Blanc, Riesling, Chenin Blanc and Sémillon are also present. Red varieties are dominated by Cabernet Sauvignon, but Merlot, Zinfandel, Cabernet Franc, and Petite Sirah are also found. As well as the main Napa Valley AVA, there are 13 other AVAs within the main area. Amongst these are Rutherford, producing some of the very finest Napa Cabernet, Oakville, Mount Veeder, Howell Mountain and Stags Leap District.
