About Clark-Claudon Vineyards
Tom Clark and Laurie Claudon planted their Howell Mountain vineyard in 1974, shortly after returning from a Peace Corps assignment in Colombia, joining the small wave of growers who helped establish Napa Valley's reputation. The family-run estate has stayed small and hands-on, with fruit hand-harvested, often at night, to select only the best grapes, and estate Cabernet Sauvignon aged roughly two years in a mix of new and neutral French oak.
The lineup centers on an Estate Cabernet Sauvignon and a reserve-tier bottling called Eternity, alongside a white wine, Wild Iris Sauvignon Blanc. The winery has no public tasting room and remains open by appointment only for personalized vineyard tours, selling through a mailing list that maintains its own waiting list, plus a dedicated program for trade accounts.
