Andrew Geoffrey Vineyards' 13 acres of red wine grapes are situated within a 60 acre parcel of prime hillside vineyard property on the highest slopes of the Diamond Mountain District sub-appellation of the Napa Valley. Diamond Mountain is located along the Mayacamas mountain range between St. Helena and Calistoga. Diamond Mountain is well known and recognized for its diversity of volcanic soils, varied micro-climates, and generous amounts of winter rainfall. Red wine grapes grown on Diamond Mountain have an outstanding reputation and Diamond Mountain red wines possess a strong consumer recognition.
Since visiting the Napa Valley in 1973, while attending college in southern California, Peter Thompson set his sights on getting into the wine business, specifically in the Napa Valley. In 1992, Peter began actively pursuing his goal of owning a vineyard in the prestigious Napa Valley. During a two and one-half year search for the ultimate vineyard property, Peter selected the Andrew Geoffrey Vineyards site atop Diamond Mountain. The property was undeveloped, but only needed the right combination of efforts to realize its incredible potential for creating a state-of-the-art vineyard to produce world class California Cabernet Sauvignon wine.
With the undeveloped land purchased in 1995, Peter set out to assemble a team of experienced professionals to carve the vineyard site out of the scrub and brush native to the Diamond Mountain soils. After a year of extensive planning, obtaining the appropriate permits and drafting of the most extensive erosion control plan ever devised in the Napa Valley, 13 acres of land were cleared and prepared with the expertise and guidance of well-known Napa Valley viticulturist Rex Geitner.
