The 2021 Schrader Double Diamond Cabernet Sauvignon from Oakville, California, is a robust and captivating red wine crafted by Schrader Cellars. With an alcohol content of 14.6%, this Cabernet Sauvignon showcases the distinctive characteristics of the Napa Valley sub-appellation.

Jeb Dunnuck praises the wine with a score of 94, describing it as "undeniably delicious" and noting its "beautiful darker currant, cassis, darker chocolate, graphite, and hints of flowers." He highlights its "concentrated" nature and "beautiful mid-palate density," recommending a decant if drinking soon and suggesting it will be enjoyable over the next 10-12 years.

Robert Parker’s Wine Advocate, through Joe Czerwinski, awards the wine a score of 91+, emphasizing its origin from Mondavi’s portion of the renowned To Kalon Vineyard. Despite using less new oak than other Schrader bottlings, it presents "cedar and celery seed notes" alongside "ripe cherries." This medium to full-bodied wine is described as "firmer, richer, and more tannic" than the similarly priced Proprietary Red.

James Suckling also gives it a score of 94, noting the "dusky, toasty, spicy oak and dark fruit aromas" leading to a "broad, dense palate" with "super velvety tannins." The wine’s "loam, tobacco leaf, graphite, and cocoa notes expand and linger," best enjoyed from 2028 onwards.

Wine Spectator matches the high praise with another 94 score, describing it as "creamy and polished," delivering "an alluring wave of plum and boysenberry compote flavors" with "textbook Oakville notes of sweet bay, menthol, and warm earth." This wine is deemed "totally ready to go," with a recommended drinking window extending through 2036.

Overall, the 2021 Schrader Double Diamond Cabernet Sauvignon is well-regarded for its depth, richness, and complex flavor profile, making it a standout choice for Cabernet enthusiasts.
