Quintessential Wines is launching two new wines from its California-based Samuel Charles brand. The newcomers include Oak Knoll Napa Valley Cabernet Sauvignon ($80 a 750-ml.) and High Valley Sauvignon Blanc ($25). The Samuel Charles brand, owned by Quintessential’s Kreps family, debuted in a handful of western states with a North Coast Cabernet. The new wines are available nationwide.
