The Isabella grape is a cultivar derived from the grape species Vitis labrusca or 'fox grape' which is used for table, juice and wine production.
The skin of Isabella when ripened is a dark purple, almost black with a tender green-yellow flesh. It has large well formed fruit clusters with thick bloom. It is a slip skin variety, meaning that the skin separates easily from the fruit. The grapes are used to make wine, most notably Uhudler and Fragolino. The Isabella being of the genus Vitis x Labruscana imparts a "foxiness" to the wine and because of this is thought to be objectionable, therefore it is not seen as a grape capable of making fine wines. For the table the flavour is good though with the astringent tough skin and "foxy" aroma is objectionable for some tastes.
The deciduous vine is very easy to propagate. When the vine is bare of leaves in winter, it is good to prune the vine back by about one-third. Save the branches that are 15 cm long and pencil-thick. Cut straight across at the proximal end (nearest the root), and oblique at the distal end. Put a bundle of about 10 cuttings in potting mix, the flat ends down, and keep reasonable moist throughout winter. They will sprout leaves and roots in spring. Divide and plant out.
Isabella, although popularly classified as being of Vitis labrusca parentage, is almost certainly a cross with an unknown Vitis vinifera, illustrated by the susceptibility to mildew and black rot. It is thought that it resulted from random pollination when European Vitis vinifera grapes were attempted to be established in America. It was popularly thought to have been discovered by a Mrs Isabella Gibbs of South Carolina in 1816, however there is conflicting information with other sources stating it was found in Virginia, Delaware and Europe. Isabella vines were heavily imported into Europe in the early 19th century and it is said that it is probable that the phylloxera was introduced into Europe on the roots of Isabella — Isabella having a resistance to the phylloxera.
