Bright, deep red-ruby. Wonderfully mellow and complex on the nose, offering everything from fresh dark fruits to chocolate, red licorice, flowers and graphite minerality. Pure liquid silk in the mouth; at once sharply delineated and edge-free thanks to superb harmonious acidity, possessing a wonderfully tight core of juicy fruit. This very dry, classic Howell Mountain Cabernet finishes with serious dusty but sweet tannins and will still improve. Stunning wine. (13% alcohol).Vinous Media | 96 VMThe 1991 Howell Mountain Cabernet is noticeably thicker and more highly extracted than the 1992 and 1993 vintages. It is a huge, rich, powerful wine with great depth, as well as a boat-load of tannin. Do not touch a bottle for at least 5-6 years.Robert Parker | 93 RP(Dunn Vineyards Cabernet Sauvignon “Howell Mountain”) I have a pretty high tolerance to brettanomyces in wine, and generally can tolerate a small amount in most bottles. That said, the ’91 Dunn Howell Mountain may be just a tad too bretty for its own good, and I am sure that there are plenty of people out there that are less tolerant of this issue and will find this wine less enjoyable than I did. The bouquet is deep and tight, with good complexity in its blend of cassis, black raspberries, medicinal tones, leather, stony soil tones, cedar and a fair bit of brett eventually emerging from the glass. On the palate the wine is fullish, young and shut down, with a good core of fruit, moderate tannins, lovely transparency down to the soil and good length and grip on the long and slightly bretty finish. If you have absolutely no tolerance for brett, knock this score down by several points, but for those that do not mind it too much, this is an impressively complex bottle of cabernet that is only a few years away from really peeking. (Drink between 2015-2040).John Gilman | 92 JGA dense, potent, rich, dark-colored wine, with immense tannins and a rich core of earth and leather-scented Cabernet fruit. Offers hints of mint, rose petal and anise, and at midpalate it gives a glimmer of polish before finishing with a wall of chewy tannins. Patience required.--'81/'91 California Cabernet retrospective.
