Black Spanish - Grapevines

Black Spanish is an older variety that is tolerant to Pierce’s disease (it can carry the disease and thus be a source of infection if insect vectors are present with no reduction in yield, but Black Spanish vines sold by Double A Vineyards are certified to be free of the disease). High in acid, color, and tannins, Black Spanish has a following in Texas where it is often used in the production of port.
