While Dunn's Cabernets slumped in quality in the difficult vintages of 1988 and 1989, the 1990s exhibit exceptional richness, depth, power, and ferocious tannins.The massive 1990 Howell Mountain exhibits huge tannin, but immense concentration. The richest Dunn Cabernet since the 1984s? Anticipated maturity: 1999-2020. At this early stage, it does not appear to be as super-concentrated as Dunn's wines from the early and mid-eighties. It is slightly more tannic. It does possess a tell-tale mineral, cassis, flowery nose, and a rich, full-bodied, dense, highly extracted, tannic personality.
