Sierra Foothills AVA is in the western foothills of the Sierra Nevada Mountains, and it includes parts of eight counties. With total acreage of 2.6 million acres, and nearly 6,000 vineyard acres, it is one of the largest appellations in California. Wine grapes were planted in the foothills during the Gold Rush in the mid-19th century and the appellation was officially recognized in 1987. There are five sub-appellations within the Sierra Foothills region, and more than 100 wineries, most small and family-owned. Zinfandel is the most successful wine grape in this region, though Syrah, Cabernet Sauvignon and Chardonnay are also planted.
The Merlot grape is such a deep blue that it is named for the blackbird. It’s an early ripening grape and one of the primary varietals used In Bordeaux. Merlot is also grown in the "International style," which is harvested later to bring out more tannins and body.
