Breeding history and breeding region
Isabella, an American by birth, is over 200 years old. The characteristics of the parental vines (Vitislabrusca and Vitisvinifera), by crossing, have been improved by the breeder William Prince.
Among the American varieties are also known Alpha, Witch Fingers and Buffalo.
Until the 80s of the last century, Isabella grapes were found in the vineyards of farmers from different countries and continents. Then, among winemakers who used the variety to make wine, it was widely believed that alcoholic beverages based on izabelnyh grape varieties contain a significant amount methyl alcohol.
As a result, arrays of bushes of different ages gradually went under the knife in the large vineyards of France and most of the states of America.
The unexpected "stain" on the brand's reputation - it is not yet known for what purpose and by whom it was delivered - does not prevent the Brazilian, Portuguese, Japanese, Korean, and Canadian growers from growing Isabella. It is also popular in the warm regions of the Russian Federation and neighboring countries:

With an abundance of birds in the region, preferring to feast on grapes, they put repellents, catching ribbons of shiny material that are developing in the wind. Nylon “cages” help against particularly persistent birds: the claws stretched over bunches of “dimensionless” material.
Before putting on protection on a brush, a bunch is examined to identify spoiled berries, free from leaves. The leaves should not get inside the protection, as they will interfere with ventilation and can lead to the development of mold on the berries.
Insects
In addition to wasps and bees willingly flocking to clusters, pecked by birds, grape greens, buds and fruits love to feast on:
- biennial moths (protect insecticide spraying at the time of the appearance of butterflies);
- grape moths (protective measures described above, prophylactic: burning leaves from vines until autumn);
- felt mites (they use spraying with sulfur-containing solutions from the misfortune);
- spider mites (help phosphamide, DNOC).
