The steady, high temperatures of the Keenan estate, on Spring Mountain above the Napa Valley floor, allowed harvest at peak maturity of the grapes. The grapes for Keenan Merlot are harvested primarily from the Keenan Estate on Spring Mountain. These grapes supply the Keenan Merlot with its rich flavor and intense bouquet. The remainder of the Merlot grapes are harvested from select vineyards on the floor of the Napa Valley. The vineyards’ grapes are hand-selected to add complexity and to soften the powerful Keenan Estate fruit.

The history of Keenan Winery started over 40 years ago. Certain that mountain side vineyards in Napa Valley could produce world class wines, in 1974 Robert Keenan purchased 180 acres in the Spring Mountain District at an elevation of 1700 feet.
