Appropriately (given its restaurant purpose), the big review for this is from the Somm Journal, at 97 points:
Energetic, with ripe notes of cherry tart and white-peppered violets. Clean and sturdy tannins take a bow on the palate with suede-like flavors of cocoa and plum that glide along a path of sweet oak.
So pretty much an archetypal Thomas Rives Brown Napa Cabernet.
The winery says:
The 2023 KHK Cabernet Sauvignon from Napa Valley is a testament to the exceptional quality of the vintage. Crafted by renowned winemaker Thomas Rivers Brown, this 100% Cabernet Sauvignon was aged for 20 months in 80% new French oak barrels from Darnajou and Taransaud cooperages, resulting in a wine that is both complex and approachable. Sourced from a vineyard in Yountville, Napa Valley, the wine offers a vibrant bouquet of ripe cherry tart and white-peppered violets. On the palate, clean and sturdy tannins support flavors of cocoa and plum, which glide along a path of sweet oak. With an alcohol content of 14. 9% and a production of 1,638 cases, this wine is designed for immediate enjoyment but also has the potential to evolve gracefully over the next 4 to 7 years.
