Dear Dr. Vinny,
What are the grape varieties that go into Port wine made in Portugal?
—Wendell B., San Rafael, Calif.
More than 80 different grape varieties are authorized for Port production, an overwhelming number I can't list here. Instead, let me tell you the most widely used—and most highly regarded—grapes: Touriga Nacional, Touriga Francesa, Tinta Roriz (another name for Tempranillo), Tinta Barroca and Tinta Cão.
