Black Spanish (grape)

Black Spanish was originally assumed to be a seedling of an American hybrid grape which resulted from a crossing of the American Vitis aestivalis species of grape with an unknown Vitis vinifera pollen donor. However, just recently it has been revealed from microsatellite DNA analysis (a.k.a. Simple Sequence Repeats or SSRs), that the American wild grapevine parent of Black Spanish (a.k.a. Jacquez) is Vitis berlandieri and not Vitis aestivalis.[1] This hybridization is not known to have been purposeful, and may have occurred naturally, as was the case with many of the early American grape cultivars. Riaz et al. (2019) have now published the genetic profile of the Jacquez grapevine as follows (percentages): V. vinifera: 69% V. berlandieri: 21% V. rupestris: 7% V. riparia: 3%.

Additional microsatellite DNA analyses conducted on various 'Jacquez cultivars' by Dr Jerry Rodrigues[2] shows that at least two of the European accessions (grapevine collections) which are presently curated in Europe were originally derived from the oldest known Jacquez cultivar (the Madeira Jacquez). The original American hybrid grape parent had found its way to the Madeira Islands sometime in the 18th century (where it was called Jaqué or Jacquet) and thence to France. Lenoir is another such seedling similar to Black Spanish which was grown and used in wine by Nicholas Herbemont[3] of Columbia, South Carolina. Many other historical names appeared throughout the early history of these Jacquez seedlings such as Jack, Blue French, Ohio, and El Paso, among others. For example, Herbemont tells us that he received Lenoir seeds from a man named Lenoir who cultivated it near Stateburg, South Carolina, in the vicinity of the Santee River sometime in the 18th century. Lenoir had made its way to Texas, where it even took on the names El Paso and Black Spanish. From its wild South Carolina parent (likely, V. rupestris), Lenoir (and also Black Spanish) carries natural resistance to the Phylloxera pest, as well as to the deadly Pierce's Disease, which is a common threat to Vitis vinifera vineyards in warm winter areas of the United States. It now appears that Black Spanish inherited its known tolerance to the deadly Pierce's Disease (PD) from its Vitis berlandieri parentage. Lenoir was also one of the American vines which the grape breeder Thomas Volney Munson[4] experimented with in the late 19th century in Denison, Texas.

Prior to its use by Munson, Lenoir was grown and used in wine by Nicholas Herbemont, although to a lesser extent than the similar, lighter-skinned variety "Warren" ("Brown French") which become known as Herbemont because of his promotion of that variety. Lenoir was introduced to Europe in the mid-19th century, where French vintners were intrigued by its similarity to European Vitis vinifera winegrapes, and gave it the names Jacquez (or Jacquet). It became an important direct producing grape in Europe during the phylloxera crisis, and later was used to some extent as a rootstock to protect the classic vinifera grapes from phylloxera. Ulysses P. Hedrick's famous "Grapes of New York"[5] in 1908 provides the seminal discussion of Lenoir and many of the early North American grapes.
