Calistoga

Calistoga received its AVA status in 2010 and is a sub-appellation of the Napa Valley AVA located on in the northern portion of the Napa Valley. Calistoga's soil is almost exclusively volcanic, providing a consistency throughout the region. The daily high temperatures up to 100 degrees and cool nightly breezes from the Russian River cause the highest diurnal temperature variation in the Napa Valley. This temperature fluctuation along with the volcanic soil creates wines with big bright flavors and deep complexity and well-balanced acid. The region is known for its Syrah, Petite Sirah, Cabernet Sauvignon, Cabernet Franc, Merlot, and Zinfandel.
