Harlan Estate is one of Napa’s most prominent wine producers, self-styled as a Napa “first growth”. The vineyard is located in the Oakville AVA, in the hills above Martha’s Vineyard (Heitz Cellar) and To Kalon (Robert Mondavi), just north of Napa town itself. Its Cabernet Sauvignon-based flagship wine is one of California’s most sought-after wines, regularly commanding prices exceeding $1000 per bottle.

The estate was founded in 1984 by property developer William Harlan, who had cut his teeth at the Merryvale winery and Meadowood lodge before buying 240 acres (97 hectares) of land in the Oakville hills. Some 40 acres (16ha) of this was cleared for vineyards – mostly planted to Cabernet Sauvignon, but with some Merlot, Cabernet Franc and Petit Verdot.
