What to Expect
SUBSTANCE Sauvignon blanc from Washington is a delightful table white wine with strong herbaceous and citrus characteristics, reminiscent of New Zealand's Marlborough region and France's Loire Valley. With its consistent presence in California and other western regions, this varietal offers a refreshing taste that reflects the best of American sauvignon blanc.
