The Tamber Bey label derives all its fruit from two privately owned vineyards, the
Tamber Bey and
Deux Chevaux vineyards, both located in the middle of Napa Valley near the town of
Yountville. Although the two properties lay a mere one-half mile from each other, they are as different as dusk and dawn due to the unique microclimates created by their proximity to Yount Hill - just north of the town of Yountville.
The
Tamber Bey Estate Vineyard consists of 11 acres located at the southern end of Napa Valley's famous
Oakville appellation, just north of Yountville. It has gravel/loam soils that are relatively shallow and well-suited to Cabernet Sauvignon grapes. The site enjoys early morning fog and late afternoon breezes that are influenced by San Francisco Bay to the south. To encourage competition for sun, water and nutrients, Tamber Bey planted over 9,000 vines in a tight planting formation on the estate.

The
Deux Chevaux Vineyard is a 60-acre parcel situated east of the town of Yountville and in the
Yountville appellation. There are two waterways on either side of the vineyard, one being the Napa River. This vineyard is planted with Cabernet, Cabernet Franc, Petit Verdot, Merlot and Chardonnay. This vineyard is influenced to a greater degree by the San Francisco Bay and the early morning fog and late afternoon winds that it generates.
Tamber Bey's Estate Vineyard and Deux Chevaux Vineyard are set at the southern end of Napa's Cabernet ripening zone. Located respectively in the Oakville and Yountville appellations, both vineyards experience the early morning fog and cool afternoon breezes off San Francisco Bay that help extend the growing season well into October. The region's unusual microclimate gives the wines an elegance that allows the geology of the site to show through without interference from overripe flavors. In addition to Tamber Bey's wines possessing all the body and lushness one would expect from the Napa Valley, they are also graceful enough to convey the unique minerality and topography of both vineyard sites.
