Kirkland Signature Signature Series Rutherford Cabernet Sauvignon is a Napa Valley red wine sourced from the historic Rutherford AVA, one of California's most celebrated wine appellations. The volcanic gravel and loam soils of Rutherford impart the wine's hallmark "Rutherford Dust" character — a distinctive, fine-grained tannic quality unique to this terroir. Crafted by winemaker Glenn Hugo and cellared and bottled by DC Flynt MW Domaines and Estates, this wine represents exceptional value in Napa Valley Cabernet Sauvignon at under $20.

The wine opens with aromas of ripe black cherry, cassis, blueberry, and dark plum, accented by notes of mocha, cedar, and warm spice. On the palate it delivers juicy dark fruit with smooth, chewy tannins, a touch of vanilla and licorice, and a long, dry finish with the signature dusty quality for which Rutherford is renowned. Alcohol is 14.5%. Critics have consistently awarded this wine 91–92 points, making it a top pick among Costco's Kirkland wine lineup and an outstanding value for Napa Valley Cabernet.

The Rutherford AVA, nestled in the heart of Napa Valley between Oakville to the south and St. Helena to the north, has produced world-class Cabernet Sauvignon for over a century. This bottling is available exclusively at Costco and typically sells out quickly given its reputation and price point.
