99 points Wine Advocate

Flirting with perfection, the 2010 Cabernet Sauvignon Beckstoffer To Kalon Vineyard RBS from clone 337 was aged in new Darnajou barrels (80%) and the rest in new Taransaud barrels. There were 410 cases produced, which is several hundred cases less than the production in 2012. An unbelievable red wine, it boasts an inky/purple color as well as abundant notes of charcoal, white chocolate, toast, new saddle leather, blueberries, blackberries, creme de cassis and licorice. As the wine sits in the glass, some chocolaty, smoky elements also emerge. This virtually perfect Cabernet Sauvignon has been flawlessly made and should age effortlessly for 25-30+ years.

Super-ripe plums, cassis, mint, mocha and violets caress the palate as the 2010 Cabernet Sauvignon RBS Beckstoffer To Kalon Vineyard opens up in the glass. The RBS stands out for its gorgeous inner perfume, sweetness and plushness. Layers of fruit build effortlessly as this gracious, highly expressive wine flows through to its plush, generous finish. The minerality of the vintage comes alive on the vibrant, beautifully delineated finish laced with sensual crushed flower overtones. This is another striking wine. The RBS is clone 337 from the B1, B2 and E2 blocks. (AG) (12/2012)

Made entirely from clone 337 Cabernet Sauvignon, this wine bursts from the glass with lavish aromas of ripe cherry, graphite, espresso coffee and liquorice. Ample and expansive on the palate, this wine’s core of fine tannins and vivid acidity will carry it along in the cellar. (WK)(2/2016)
