The colour of the Howell Mountain Cabernet is noticeably darker than the Napa Valley bottling, showcasing an incredibly intense, mineral-driven profile. The tannins have an ironstone-like quality—firm, structured, and reminiscent of that "iron fist in a velvet glove" metaphor. The palate has remarkable density, balanced by a pure, vibrant mix of tart red berries and black cherries. The tannins become more assertive, but as they gradually soften, a rush of juicy blood orange acidity emerges. The wine carries intriguing layers of sagebrush, cedarwood, and warm brown spices, delivering ample power and complexity. 100% Cabernet Sauvignon fermented in stainless steel tanks, aged up to 32 months in 100% new French oak.

A deeper, richer, more powerful wine, the 2021 Cabernet Sauvignon Howell Mountain sports a deep ruby/plum hue to go with a Pauillac-like nose of blackcurrants, scorched earth, graphite, and lead pencil notes. It's full-bodied, incredibly concentrated, has the classic Howell Mountain tannic structure, and a gorgeous finish. Give bottles 7-8 years if you can and enjoy over the following 2-3 decades. 

98 points James Suckling

Robust and brooding aromas of mulberry bush, violets, cedar, cocoa and graphite. The palate is full-bodied with refined tannins and bright acidity, giving notes of blackcurrants, spices, tobacco leaves and crushed river stones. Very bold and generous, with a refined structure that will age gracefully. Drinkable now, but best from 2028.
