The Influence of Yountville Climate
The Influence of Yountville Climate on Grape Growing
Yountville’s climate consists of sunny, warm summer days that are cooled by regular afternoon breezes. Marine air from San Pablo Bay affects the AVA, but far less than windswept Carneros to the south.
Evenings are substantially cooler than in AVAs located further north. The western part of the viticultural area is particularly cool and enjoys a long, methodical growing season. While Yountville is widely planted with Cabernet Sauvignon, mild temperatures allow for many other varietals to be grown successfully.
The valley walls specialize in Cabernet Sauvignon, Merlot, Cabernet Franc, Petite Verdot and Syrah. Chardonnay is the most widely planted white varietal. Zinfandel, Syrah, Sauvignon Blanc and Pinot Noir are also substantially planted.
Gemstone Vineyard is a noteable property that makes one of the better Bordeaux blends in Napa. The Bordeaux educated Philippe Melka is the head winemaker. Gemstone Vineyard is planted with several carefully selected clones of Cabernet Sauvignon, Cabernet Franc, Merlot and Petit Verdot. Leaves and grape clusters are pruned to allow maximum sun-exposure.
Domaine Chandon is the largest winery in Yountville. They produce excellent sparkling wine on their beautiful property. Rocca Family Vineyards was established by Mary Rocca and Eric Grigsby in 1999. They make a Cabernet Sauvignon, Merlot and Syrah.
