Wine enthusiasts know that the taste of the grape reflects the climate and weather of the area where vines grow. When temperatures are too cool, grapes are tart. If temperatures rise, grapes can overripen or dry out. Too much rain can dilute the flavor and change the sugar/acid balance of the fruit. Too little moisture reduces the yield of grapes, which means less wine!
Fortunately, the U.S. is home to Napa Valley and its sub-appellations, where conditions for winemaking are optimal. An appellation is a defined region where grapes are grown. Napa’s diverse landscape creates smaller areas or sub-appellations with unique climates (and exceptional wines). Sub-appellations are also known as American Viticultural Areas or AVAs.
Read on to learn about each of the 16 sub-appellations and choose the areas that match your wine preferences.
- Atlas Peak. Cool and rugged with drier soil, the Atlas Peak sub-appellation produces bright Cabernet Sauvignon and crisp Chardonnay.
- Calistoga.The highs and lows of Calistoga’s temperatures help produce balance in the AVA’s Zinfandel, Syrah, and Cabernet Sauvignon wines.
- Chiles Valley District. Cooler temperatures and higher elevations lead to later harvests, but the Merlot, Cabernet Franc, and Zinfandel from this AVA are worth the wait.
- Coombsville. The moderate climate of Coombsville helps deliver the soft and earthy flavors in the region’s Pinot Noir, Merlot, Chardonnay, and Syrah.
