Dunn's status as a benchmark Napa producer dates back to 1978, when Randy and Lori Dunn purchased a 14-acre parcel in Angwin on Howell Mountain, planted to five acres of Cabernet. When Howell Mountain became an American Viticultural Area in 1983, Randy was one of the growers leading the way. The estate is still, happily, family-run, now in its third generation as young Alex (Randy's grandson) joins second-generation Kristiana and Mike Dunn. As much as Napa has changed since the '70s, some things haven't, and Dunn remains one of the touchstones of classic Napa.
