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.
