Lewelling Vineyards is in St. Helena. It was founded in 1864 by John Lewelling, a winemaker and horticulturalist. His great-granddaughter, her husband and their three adult sons still own and operate the 28-acre estate. Lewelling makes Cabernet Sauvignon that impresses reviewers. Robert M. Parker Jr. rated several of the 2007 Cabs in the high 90s and wrote that “One can’t say enough about the wines produced at this extraordinary site in Napa Valley.”
