Grade of grapes Isabella.

Isabella is a table-technical grape of a late ripening period, bred by American breeders in the 18th century as a result of natural hybridization of Vitis labrusca and Vitis vinifera. It is one of the oldest grape varieties on our planet, unpretentious to the natural and climatic conditions and has good yields (60 - 75 kg / ha). In the USA - in the homeland of its origin, including even those areas where they are mainly engaged in growing hybrids with Vitis labrusca (New York and Great Lakes) - this variety has long been supplanted by other more popular hybrids of this culture. Currently, Isabella is mainly used for fresh consumption; in winemaking - for the preparation of low quality wines (wines made from this variety have a high content of methanol and a very specific flavor - a pronounced aroma of rot); and also increasingly used for decorative purposes - for landscaping.

Isabella grapes is a vigorous, climbing bush covered with dark green and also quite often gray (as a result of thick felt pubescence) leaves of three-lobed type, medium and large size. The reverse side of the sheet is greenish-white. The plant possesses a vaulted, with a sharp bottom, an open pedicle notch and bisexual inflorescences. The clusters are of medium dense structure (sometimes friable), of medium size (weighing up to 120-150 grams), in most cases almost cylindrical in shape (less often in a regular cylindrical shape), with small “wings”.

The berries of this variety are of medium size, round or oval in shape, with a strong, thick skin, dark blue (almost black) color with a bluish tinge, richly covered with a waxy bloom. The pulp of the berries has a mucous structure with a pronounced strawberry flavor and has an average sugar content (16-18%) and acidity (6-7 g / l).

Grapes Isabella has good winter hardiness, which allows it to be cultivated in most cases as a non-roofing type of plant. The most favorable for this variety are poorly fertile soil. It is well tolerated by high humidity, a little worse - drought, which has a negative effect on the plant, dramatically reducing the growth force of the bush and in some cases leading to leaf fall. Isabella also has a high resistance to fungal diseases and phylloxera. It grows well and bears fruit in the most diverse climatic zones. The period of formation of the crop - the average, is 150 - 180 days from the moment of blooming of the kidneys to the full ripening of the berries.

When cultivating this grape, it is recommended to carefully ensure that there is no strong thickening of the leaves, which, in turn, can cause uneven ripening of berries, mildew, reduced sugar accumulation in the juice of the berries and, as a result, deterioration in the quality of the crop. Showing clusters by thinning the leaves and a relatively moderate load on the plant allows you to get the most volumetric and high-quality crop.
