Schrader RBS is a prestige Cabernet Sauvignon sourced exclusively from the renowned Beckstoffer To Kalon Vineyard in Oakville, Napa Valley — a site originally established by H.W. Crabb in 1868. The "RBS" designation identifies Clone 337, grown on the Beckstoffer family's portion of this legendary first-growth vineyard. The wine is crafted by celebrated winemaker Thomas Rivers Brown for Schrader Cellars, which was founded by Fred Schrader in 1998 and is now part of the Constellation Brands family.

The RBS is aged 18 months in 100% new French oak barrels from Darnajou and Taransaud cooperages, yielding a wine of remarkable concentration, purity, and silky texture. On the nose, it delivers violets, cassis, ripe red berries, cedar, and delicate cinnamon and clove nuances, with a graphite backbone lending structure and depth. The palate is full-bodied and plush, with supple tannins, a vibrant mouthfeel, and a long, fruit-filled finish. Critics consistently award the RBS 96–97 points across vintages, with Jeb Dunnuck, Robert Parker's Wine Advocate, James Suckling, and Wine Spectator all lauding its elegance and aging potential. Schrader Cellars has earned a total of 27 perfect 100-point scores across its portfolio.

This wine can be enjoyed in its exuberant, fruit-forward youth or cellared for 15 to 20 years or more. Decanting for 1–3 hours is recommended for young vintages. Best served at approximately 60°F (15.5°C). Pairs beautifully with beef, lamb, game, duck, roasted meats, and rich braised dishes.
