Tinta Francisca
Tinta Francisca is a red-wine grape variety grown in the Douro region of Portugal. It is commonly used as a blending component in fortified Port wines. The variety is known for its high sugar content and lack of structured acids, tannins and aromatic complexity. Tinta Francisca is often confused with Touriga Franca, another grape variety from the same region. It is speculated that Tinta Francisca may be a distant relative of Pinot Noir, but this theory is unproven.
