The red grape variety originates from the USA. Synonyms are Black Ives, Bordo (Brazil), Grano d'Oro, Ives, Ives Madeira, Ives Seedling, Ives' Madeira Seedling and Kittredge (Australia). It is an open-pollinated seedling of the variety Hartford (Vitis labrusca), discovered in 1840 by a Henry Ives near Cincinnati in the state of Ohio. According to other sources, it was found in 1846 in West Hartford, the capital of Connecticut. It probably originated from a natural cross between Isabella x Labrusca, according to a second hypothesis between wild vines of the species Labrusca x Aestivalis. Ives himself claimed that the variety originated from a seed of a European vinifera called Madeira. So there are genes from Vitis labrusca and perhaps also from Vitis aestivalis and Vitis vinifera. It is possible that there is a relationship with Bordô, which is cultivated in Brazil. It was a crossing partner in the new Montefiore variety.
