| Napa Valley’s Coombsville Appellation lies in the foothills of the Vaca Mountain Range. The foothills were created by volcanic ash, covered by alluvial flows, which formed cobble-filled layers of rich loam.
The volcanic Mt. George and Atlas Peak are to the northeast with the Napa River basin to the west. San Pablo Bay is to the south, moderating cold in winter and heat in summer, making Coombsville one of the most temperate of the Napa Valley appellations. Grapes mature slowly and ripen evenly during the long growing season. The resulting flavors are bright with brilliant acids, soft but significant tannins, excellent structure and mouthfeel, and a foundation of earth and mineral flavors.
The vineyards consist of roughly 9.5 acres and are planted with slightly more than 13,000 vines of the Bordeaux varietals; Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec and Petit Verdot.more on the Vineyard
The topography is varied with north, south and west facing hillsides as well as several acres of flat land each of which present different exposures. Vineyard rows are oriented to take advantage of the sun but planted in such a way as to minimize fruit sun burn. The vineyard also has several microclimates. Low lying areas will be several degrees cooler than the tops of the hills. Furthermore the soil on the hillsides is different than on the flat land having eroded, over the eons, to the flatter areas
