Since 1979, Randy and Lori Dunn have owned and operated Dunn Vineyards and continue to produce one of the most highly acclaimed Cabernet Sauvignons from Howell Mountain and the Napa Valley.
In 1978 Randy and Lori purchased a 14-acre parcel in Angwin with about 5 acres of Cabernet vines on it. At the time, Randy was working full-time as a winemaker in Rutherford. In the evenings and on weekends, Randy, Lori, and a young Mike tended the vines. The same year, Randy agreed to farm and buy the fruit from Harry Frank's adjoining property. That first harvest yielded 9 tons of fruit from these two vineyards. Randy purchased an additional 3 tons from the Beatty Ranch and Dunn Vineyards was underway. Everything picked up speed after that. Randy, Lori, Mike and baby Jennifer moved onto the property that today is the winery. In 1981, the winery was officially bonded. By 1984 the ATF approved Howell Mountain as a sub-AVA of the Napa Valley. Kristina was born and Lori was now running after 2 young daughters and a teenage son. Randy was still working down in the valley so the family business was still relegated to evenings and weekends. But things were going well. By 1985 they moved into the new family house (the "Brown House") and Randy left his job in the valley. By the end of the '80's Dunn Vineyards had become a successful operation. Randy was consulting for other wineries and selling out all of his wine. In 1989 he had run out of room to store barrels and he tunneled into the mountain to make more space. Now they had room for more barrels and a place for Jenny and Kristina to rollerskate. In 1999, Mike came back to help out part-time. It took about three years, but the "cellar grunt" came on full-time. Kristina graduated from Cal Poly with a degree in winemaking and viticulture and came onboard. By 2005, both kids were working full-time for Randy. Dunn Vineyards had always been a family business, but this was a whole new level. Kristina's girls are a little young yet, but they tour the vineyards eating wild blackberries, testing grape ripeness and visiting uncle Mike. Mike's son Alex has been helping out with bottling for the past several years and 2017 was his first full harvest. So far it looks good for the Dunn clan to continue farming this land. There are some distinct benefits to being above 1400 feet in elevation. We tend to see more sunshine each day and the heat tends to be more moderate. But spring starts later for us and, like winter, tends to be cooler here than on the valley floor. Frost is a concern from bud break through flowering. In 2008, four days of 19-degree temperatures devastated half our crop. Our yields average about 2 tons an acre (which is really low) but the cool, wet vintages do not have the same negative effects that come with being on the valley floor. We farm about 42 acres of Cabernet Sauvignon on the property. This is a manageable size for us to remain in the driver's seat for all farming and winemaking operations.
This signature wine contains only fruit farmed on Howell Mountain. The wine comes in a distinctive bottle that is hand dipped in red wax. 100% Cabernet Sauvignon. aged 32 months in 100% new French oak.

Dunn Vineyards Napa Valley Cabernet Sauvignon is made from 100 percent Cabernet.
This Napa Valley wine is a blend of their Howell Mountain fruit and a small quantity of valley floor fruit that they purchase. This valley floor fruit contributes to the wine’s earlier approachability and softer tannic structure.
Review:
I loved the 2019 Cabernet Sauvignon Napa Valley, which I think is a step up over the 2018, although both 2019s show a much more elegant profile. Ripe currants, plums, roasted herbs, violets, and incense notes all shine in this medium to full-bodied, ripe, supple, layered beauty, which has fine tannins and a gorgeous finish. Enjoy bottles any time over the coming 15 years.

G.D. Vajra Bricco Delle Viole Barolo is made from 100 percent Nebbiolo.
The Barolo Bricco delle Viole shows the signature verticality of its vineyard. The wine is beautifully layered and - while restrained as it’s always the case in the youth of Bricco delle Viole - it also shows a complexity of layers with purple flowers, sweet spices and mineral tones. The palate is noble, with a refined acid spine and profound tannins that promise a long aging potential.
Among the historical vineyards of Barolo, Bricco delle Viole is the highest and the closest to the Alps. It rises from 400 to 480 meters above sea level, on the Western ridge of the village. Its name, “Hill of Violets”, originates from the flowers that blossom early here due to the perfect south exposure. Up above the fogs, Bricco delle Viole enjoys the earliest sunrise and the last sunset every day. Thanks to its vines dating back to 1949 and -now- 1931, a dramatic diuturnal temperature range and this pure light, Bricco delle Viole generates a sophisticated and profound Barolo DOCG of bright aromatics, chiseled tannins and subtle minerality. 2018 is a vintage that shows many nuances of Bricco delle Viole: beyond the signature verticality of this site, the wine offers high tones laced with mineral nuances and plenty of energy and youth.
Review:
A juicy Barolo, with vibrant acidity and a fluid profile that exudes cherry, raspberry, mown hay, mineral and eucalyptus aromas and flavors. Tight yet long, with excellent potential.
#26 Wine Spectator Top 100 of 2023
The last wine poured at my tasting at the winery is the G.D. Vajra 2019 Barolo Bricco delle Viole. With its high vantage point in the hills west of Barolo, Bricco delle Viole is a world apart in terms of soils (with Sant'Agata marl and fossils) and even harvest times. Slow and careful ripening like the kind that characterizes fruit in 2019 renders a very delicate and ethereal expression with floral tones, wild mint and licorice. This organic wine is solid in build and structure. Indeed, Isidoro Vaira remarks that Nebbiolo tannins have changed since the 1970s and 1980s.

Jeweled in appearance, the 2019 Barolo Bricco Delle Viole may be the best wine I have tried yet from Vajra. Its gorgeous and alluring perfume of fresh roses is followed by a Burgundian, elegant red with incredible length and no harsh edges, fine and present tannins, and beautiful, graceful concentration. It is drinking well now, and I will be trying to get my hands on as much of this as possible. Drink 2025-2045.

Signature Cabernet Sauvignon is made from 79% Cabernet Sauvignon and nearly equal portions of Petit Verdot, Malbec, and Merlot.
The Signature Cabernet Sauvignon has been a foundational wine for more than five decades. It is a benchmark for the long-lived hillside wines of the Napa Valley, full of structure and aging potential, yet seductively forward in its concentrated varietal character. The dry, rocky soils of Pritchard Hill produce small, intensely flavorful grapes. Crop thinning allows for full, even ripening and elevates flavor complexity.
Review:
Nine different Cabernet clones joined forces for the 2022 Signature, a wine designated in what the winery offers only in extraordinary vintages. The final blend of 82% Cabernet Sauvignon, includes Petit Verdot, Malbec, and Merlot in small quantities. Luscious, as expected, a bath of puréed black cherries and milk chocolate match with teeth-coating plum skin tannins. Spiced red tea, Italian herbs, and a trace of cinnamon-cedar are left behind on the long, silky finish. - The Tasting Panel, July/August 2025
