Diamond Mountain District AVA

The Diamond Mountain District AVA (American Viticultural Area) is a wine region located in the northern part of Napa Valley, California. It is known for its high-quality Cabernet Sauvignon wines and is recognized as one of the premier wine-growing regions in the United States.

Geography

The Diamond Mountain District AVA is situated on the western slopes of the Mayacamas Mountains, which separate Napa Valley from Sonoma Valley. It covers an area of approximately 5,000 acres, with vineyards planted at elevations ranging from 400 to 2,200 feet above sea level. The region's unique topography, volcanic soils, and cool climate contribute to the distinctive character of the wines produced here.

Climate

The climate in the Diamond Mountain District AVA is influenced by its proximity to the Pacific Ocean and the San Pablo Bay. The region experiences warm, sunny days and cool nights, which allow the grapes to ripen slowly and develop complex flavors. The diurnal temperature variation also helps to maintain the acidity and balance in the wines.

Grape Varieties

The primary grape variety grown in the Diamond Mountain District AVA is Cabernet Sauvignon, which accounts for the majority of the vineyard plantings. The region's volcanic soils and unique microclimate are particularly well-suited for growing this varietal, resulting in wines with intense flavors, firm tannins, and excellent aging potential.

In addition to Cabernet Sauvignon, some vineyards in the Diamond Mountain District AVA also cultivate small amounts of other Bordeaux varietals such as Merlot, Cabernet Franc, Petit Verdot, and Malbec. These grapes are often used in blending to add complexity and depth to the wines.
