Rubired

From Wikipedia, the free encyclopedia

Rubired is a variety of red grape used to make red wine in several Australia vineyards. It is also a major source of red food coloring in California.

The variety was created by Dr. Harold Olmo, a viticulturist, at UC Davis in California as a blend of the grapes Tinto Cão and Alicante Ganzin. Originally intended to create port, its intensely dark colour means that it is often used as a colouring in other red wines, but it is also used to make a red wine in its own right.
