There are a lot of varieties of seedless grape varieties. They are very popular for their taste. There is a lot of discussion among winegrowers about the peculiarities of one of them - the Black Finger variety.
Breeding history
The history of this variety is mysterious. Many confuse it with the work of Israeli scientists - the Black finger grape. In fact, the authors of this wonderful variety are Italian specialists in the field of selection and agriculture, whose goal was to create seedless grapes for table use. It is not known exactly how the breeders got the Black Finger, but, most likely, its origins originate from the Asian roots of the Vitis Winifer species.
Some vineyard owners know this variety by different names, which also adds to the confusion. He hides under synonyms: Vitroblack, Black Finger type and simply Kishmish Black Finger. Many are familiar with the fabulous name of kishmish Alyonushka, as well as the Shakespearean version of Ophelia (Ophelia). The latter name is also patented.

Due to its excellent transportability, the grapes of this variety, even during long-term transportation, perfectly retain their external attractiveness and presentation.
Ripening period
In its historical homeland, the variety is considered early. In Ukraine and in the south of the Russian Federation, Black Finger has an early to medium ripening period. The growing season is 115-125 days.
Bunches
The bunches of the Black Finger are beautiful, very appetizing in appearance. They are cone-shaped, with noticeable asymmetry. The grapes are harvested at a moderate density. The weight of the bunch is about 800 g, some of them reach more than 1 kg.

Taste
Under the skin of medium thickness there is a fleshy, very juicy pulp with a combination of harmonious and light nutmeg flavor. The juice is lightly colored.
Yield

Growing features

To obtain a pulp, in which stone formations will be completely absent, treatment with a growth activator (gibberellin) is carried out during mass flowering. Use a solution with a substance concentration of 30 mg / l. After 2 weeks, the procedure is repeated.
Landing
It is preferable to choose places where there is no closely located groundwater.
Vines can be formed using the ceiling method (on an arch, arbor) or using ordinary trellises. This will help to form a bush of the required shape, provide access to sunlight to all parts of the plant.
