Tasting note

Dunn Vineyards' 2021 Howell Mountain Cabernet Sauvignon should suggest cassis, blackberry and cedar, with dark plum beneath. Expect a concentrated mountain style palate, firm tannins building a strong frame while acidity keeps the fruit focused. The opening window begins in 2028, with peak years from 2030 to 2055 and a horizon of 2060. A long finish should carry dark berry, savory spice and earthy depth.
