What to Expect
Los Napas Sauvignon blanc is a vibrant white wine with notable herbaceous and citrus flavors, reminiscent of the grape's traditional home in New Zealand's Marlborough region or France's Loire Valley. As it appears under both "Sauvignon Blanc" and "Fumé Blanc" in U.S. COLA registry, you can expect its consistent presence across California and other western regions, making it a familiar choice for those seeking the classic Sauvignon blanc profile.
