Grapes Krasnostop Zolotovsky

The mid-early grape variety Krasnostop Zolotovsky has a technical purpose, an interesting and variable history of Russian origin. Designed for the production of dry and semi-sweet wines as a sole ingredient or blending with other varieties.

Despite the officially recognized authorship of the breeders of the VNIIViV them. Ya. I. Potapenko, branch of the Federal State Budgetary Scientific Institution "FRANTS", there are several interesting theories of the origin of the Krasnostop Zolotovsky grape variety.

1. One of the versions refers to Don winemaking and European Cabernet Sauvignon. It is believed that the first seedlings appeared in this area in 1812 and were brought by the Cossacks.

2. The second version of the origin of grapes is associated with the Caucasus. The Russian winegrower A.I. Potapenko is sure that Krasnostop is of Dagestan origin and was brought from there in the 8th century.

3. According to the third theory, Krasnostop is considered an autochthonous variety. This opinion appeared after the study of three Don varieties by the Swiss ampelograph Jose Vuaymo: Krasnostop Zolotovsky, Sibirkovsky, Tsimlyansky Black. After comparing their DNA with a database of profiles of more than 2000 world varieties, they did not find a single match. As a result, the scientist came to the conclusion that the Don varieties can be safely attributed to aboriginal, including Krasnostop Zolotovsky.

In any case, it remains an excellent base for aromatic wine.

The variety is zoned for the Krasnodar Territory, the Rostov Region, bears excellent fruit in the Crimea, Dagestan and in neighboring republics.

Medium-sized bushes with a fully ripening vine are covered with five-, three-lobed leaves. The surface of the glossy, but wrinkled leaf plate is covered with a fine mesh of veins, and has a pubescence on the back. The petiole, like the central veins, is wine-red. The edges of the leaf are covered with small serrated teeth.

The required sum of active temperatures for Krasnostop Zolotovsky is 2820, the average number of days before the acquisition of technical ripeness is 136. At home, in the Don region, the variety opens its buds at the end of April, the berries ripen in the first decade of August. A characteristic feature is the uneven onset of technical and physiological ripeness - the longer the berry remains on the vine, the lower the acidity level, therefore, it is permissible to delay the harvest.

Medium-dense, sometimes loose, slightly conical or cylindrical brushes weigh 175–220 g. However, both weight and size depend on the place of growth and soil moisture. Dry soil contributes to the formation of loose, medium-sized brushes of 50-60 g. On wet soil, the weight reaches its maximum values.

Black-blue, with a purple hue, rounded berries are covered with a thick prune bloom. Slightly slimy, juicy, spreading pulp is hidden behind a thin, easily detachable skin. The berries are medium in size and reach 13 mm. Sugar content - 250, acidity - 10-10.5 g / dm³, but the fruits tend to lower acid levels by the time they reach physiological ripeness.

The variety has a harmonious taste with light fruity notes.

Krasnostop Zolotovsky is considered a medium-yielding variety.On average, 60-80 centners are harvested from 1 hectare.

The cultivation technique is standard, its observance and the correct choice of place allow you to get stable yields.

Landing is carried out in spring and autumn, but experts prefer the autumn period. Before planting seedlings, you need to choose the right, most favorable place. These are the southern and eastern slopes, without the close occurrence of groundwater. Krasnostop loves all-round illumination by the sun's rays, protection from drafts and northern winds.

For planting, pits of a standard size are prepared: 80x80x80 cm. A drainage layer of broken brick, small pebbles, etc. is laid on the bottom. The soil is enriched with superphosphate, manure, compost. If seedlings are planted on fertile chernozem soils, then young plants do not need additional nutrition in the first years of life. This rule does not apply to depleted areas. The distance between bushes and rows is 1.5–2 meters; before planting, the roots are treated with a clay-dung chatter.

The vine is characterized by bisexual flowering and does not require additional pollination.

The grapes need spring sanitary pruning. It is carried out to form strong bushes and increase yields. Pruning in the first year of life promotes the growth of shoots and vegetative mass. In the fall, a short pruning of 2-4 eyes is carried out.

For grapes of this variety, moderate watering is required at the beginning of growth and development, and abundant watering during dry periods.

Before the start of sap flow, nitrogen and organic matter are introduced into the soil (chicken droppings 1: 20). Two weeks before flowering, the bushes are sprayed with sodium humate (4 g per 10 l of water). In autumn, the soil is dug up with organic fertilizers: manure, compost, humus.

Moderate frost resistance - the variety tolerates a drop in temperature to -20 degrees, but needs shelter. Cover the vine with a trench method with a depth of at least 30 cm.Shoots are removed from the support, tied and placed on pre-laid boards. The soil is poured on top and covered with a film or agrofiber.

Despite the comparative resistance of the variety to fungal diseases and mildew - 2 points, it needs preventive fungicide treatments. In order to prevent an attack by a grape mite and phylloxera, it is sprayed with insecticides.

Storage of technical grapes is not provided - it is immediately sent for processing to wineries.

Most of the vine owners of this variety are grateful for its unpretentiousness and stability of fruiting.
