Keenan Winery Cabernet Franc Spring Mountain is a 100% estate-grown red wine from the Spring Mountain District AVA on the western slopes of Napa Valley. The grapes are sourced from Keenan's highest vineyard, situated at approximately 2,000 feet elevation in the Mayacamas Mountain Range, giving the wine remarkable concentration and structure.

The wine showcases ripe black cherry, plum, and blueberry with hints of herbaceous earth, cloves, and espresso. On the palate it is well structured with round, silky tannins and a long, velvety finish. Fermented in stainless steel tanks and aged in French and American oak barrels for approximately 20 months, the wine is built to age 10–15 years. Alcohol is approximately 14.5% by volume; residual sugar is dry.

Robert Parker Jr. of the Wine Advocate described Keenan as "a marvelous source of top-notch Cabernet Franc," calling their Spring Mountain bottling "one of the finest made in California." The wine consistently earns ratings in the mid-90s. Each vintage is produced in extremely small quantities, making it one of the rarest Cabernet Franc wines in Napa Valley.
