Grapes "Pineapple" refers to varieties of universal purpose. This standard seedling of the famous Isabella variety is a clone of Ferdinand de Lesseps grapes.
Pineapple grapes were obtained by American breeders as a result of interspecific hybridization of the popular varieties Vitis Vinifera and Vitis Labruska. The name of the derived grape variety is due to the similarity of the aroma of ripe berries and the tropical plant of the same name. Beginner growers often confuse this variety with the grape variety "Pineapple Early", which was the result of the work of breeders from France. In addition, the grape variety of the same name is known, which belongs to the selection from K.P. Skuin on the basis of TSHA.
