What to Expect
PORTENTO Sauvignon Blanc, a white grape with strong herbaceous and citrus characteristics, is part of the sauvignon-blanc family. While its origin remains unknown, it shares similarities with New Zealand's Marlborough region and France’s Loire Valley, where it often appears under the alias "Fumé Blanc." In the U.S., you can find it in California and other western regions, reflecting its consistent commercial presence there.
