2015 Mark Herold Wines Coombsville Cabernet Sauvignon

Mark Herold earned a Ph.D. in Ecology at U.C. Davis before starting his career in winemaking. He was a research enologist at Joseph Phelps Vineyards then in 1998 started making Merus, a cult Cabernet Sauvignon, in his Napa garage. Since then he’s been a consultant to wineries throughout Napa Valley and he has continued to make wines under his own name. He is best known for his full-throttle Cabernet Sauvignons, though he also makes blends and whites that are unusual for California. Herold’s non-Cabs include Tempranillo, Grenache, Carignan, Albarino and Verdejo blends. His Cabs, and some other wines, typically earn ratings in the low- to mid-90s from reviewers.

Coombsville AVA is one of Napa Valley’s newer appellations, having received its official designation only in 2011. Tucked just to the northeast of Los Carneros and a few minutes’ drive east of downtown Napa, the Coombsville appellation is relatively large at a total of 11,000 acres. The elevation varies from 100 to 1,000 feet, and the climate is moderated by marine breezes from the San Pablo Bay. The main grape varieties here are Cabernet Sauvignon, Merlot, Chardonnay, Syrah and Pinot Noir.

One of the most widely grown grape varieties, it can be found in nearly every wine growing region. A cross between Cabernet Franc and Sauvignon Blanc. It’s a hardy vine that produces a full-bodied wine with high tannins and great aging potential.
