The California winery is located in Yountville in the AVA area of the same name Napa Valley, At this point Georg Yount, after whom the area was named, created a vineyard called "Napanook Vineyard" in 1836 (meaning "Napa corner of Weingarten"). As a result, there were several owners, including the wine-growing pioneer Hugh La-Rue and John Daniel, the grandnephew of Gustave Niebaum and former owner of Inglenook Winery, In 1982 the vineyard was built by Christian Moueix, the owner of the Château Petrus in the Pomerol, revived in a joint venture with the two daughters of John Daniel under the new name "Dominus Estate". The first year was 1983. Since 1995 Moueix has been the sole owner. The vineyards cover around 50 hectares of vineyards on gravel and clay soils, some of which are still with Cabernet Sauvignon. Merlot and Cabernet Franc planted from 1880. It is the oldest vine in Napa County.
The flagship of the house is the extremely durable Bordeaux blend "Dominus", mainly from the Cabernet Sauvignon variety with slightly fluctuating smaller portions of Merlot, Cabernet Franc and Petit Verdot is pressed. This developed, particularly due to the outstanding vintage 1990, into a very popular one cult wine, On the label Christian Moueix was portrayed from 1983 to 1990 with a portrait and signature in different forms by artists. The label has been the same since the 1991 vintage. It no longer bears the image, but only the signature of the owner. Since 1996 the label "Napanook Wines" has been a young one to enjoy second wine generated.
