Wine is a noble drink that takes its origins from ancient times. And growing grapes is a whole art. Each wine is named after the grape variety used in its production. Grape varieties have different colors, tastes, and different purposes. This "special" grade is the Black Doctor.

Breeding history

The development of wine based on the Black Doctor variety began in the 1930s, but was not in demand until the 60s. The original name of the grape variety is Ekim kara, which means Black Doctor or Black Doctor. The name is not accidental, since it is wine based on this type that heals joint pain and muscle spasms, liver pathologies, is used for the prevention of cancer and many other ailments.

There is a legend that they began to call grapes and wine made from it the Black Doctor after an absurd incident. A physician healed a dying colonel by giving him a jug of wine made from a then unnamed grape variety. The colonel felt better, but exhausted and drunk he fell asleep at the same moment. After his awakening, he remembered absolutely nothing and, seeing the doctor in front of him, indiscriminately shot him. The people say that after this there was also a wine named after the colonel - the Black Colonel.

In addition to the names Black Doctor, Black Doctor and Ekim Kara, the variety is called Kefesia and Kefe raisins.

Geography of distribution

The cultivation of this technical variety occurs exclusively in the Crimea and belongs to the group of eastern vineyards.

Description

This variety is often used to create juices, compotes and preserves, as well as wine and other alcoholic beverages. The juice of the grapes itself has no color. The Black Doctor variety contains 2-4 seeds in each berry.

Ripening period

Ripening of grapes varies from 130 to 157 days and is calculated from the beginning of the growing season, that is, from the highest activity of the plant. It all depends on the surrounding climate and temperature changes.

Bunches

Most often, the bunches are broadly conical or lobed. The density is loose. The weight of the bunch is 148 grams, the length is about 16 cm, and the width is about 12 cm. They contain up to 90% of the pulp and only 4% of the skin.

Berries

The berries are deep black, have a rich waxy layer. The skin is thick, the flesh is juicy and the shape is round. Each berry weighs on average 3-5 grams.

Taste

Black Doctor has an amazingly harmonious taste, combining notes of chocolate and prunes.

Yield

High yield is one of the many advantages of the Black Doctor. The fruitfulness of the shoots is 60% on average.

The choice of planting material
Experienced gardeners recommend that beginners take cuttings and seedlings from those who made them from their vines and are professionally engaged in the production of such material.
You can evaluate the quality by cutting off a small amount of bark. When growing a bush from a cuttings and observing the rules of agricultural technology, survival rate is about 90%, the high quality of the plant is practically guaranteed. It is possible to control the development of grapes at all stages.
Subject to the rules of agricultural technology, survival rate is about 100%. The seedlings must be healthy. Pay attention to the absence of blisters, growths, or other signs of disease.

Growing features

Planting occurs with pollinating varieties such as Saperavi, Bastardo Magarach and others.

Landing

When planting, it is imperative to take into account the access of light to the plant, since the sweetness of the berries depends on the rays of the sun. To facilitate maintenance and collection, the bushes are tied onto trellises with a height of 2 meters.

Early spring and late autumn are favorable times for planting.

Landing features
In order for the vine to give a signal harvest after 3 years, it is necessary to take into account many factors - from the type of soil on the site to the nearby plants.

Pollination

The black doctor has a functional-female type of flower, which means that the variety cannot self-pollinate. Therefore, in addition to artificial pollination, which can be done both manually and with the help of special devices, additional pollination with a variety of any bisexual grape is required. To do this, when planting 2 different varieties, they are planted through one, providing the so-called cross-pollination.

Pruning

Pruning always takes place in winter, since the sap flow inside the grapes slows down or completely stops. This means that the vines will not be damaged.

Pruning is one of the main grape care procedures. Depending on the purpose of pruning and the type of plant, the appropriate type of formation is selected.
Irrigation schemes
In order for the berries to be large and juicy, it is necessary to organize full watering and feeding. All standards must be adjusted for weather conditions and the rate of evaporation of the liquid.
With a frequent watering scheme, it is recommended to moisturize once every two weeks (that is, twice a month during flowering and the appearance of berries) so that the earth is saturated 50 cm deep so that the plant does not switch to superficial (dew) roots. This amount can be reduced by mulching the crop with straw.
With a rare irrigation scheme, choosing the age and ripening period of the grapes, you can use the standards presented in the table in another article.

Frost resistance and the need for shelter

The grapes are grown in the southern regions and in most cases do not require special shelter. Has a very high frost resistance up to -23 degrees.

Shelter for the winter is a very important step for the preservation of many grape varieties after wintering.

Diseases and pests

The most important diseases of the Black Doctor grapes are mildew and oidium.

Mildew is a fungus, after the appearance of which the leaves and buds turn yellow and eventually fall off. If you do not take measures for the processing of plants in time, then there is the possibility of losing the entire crop.

Oidium is a gray-white bloom that makes the berries completely unsuitable for making wine. The fight against this disease is the same as with mildew - treating the bushes with a special solution containing sulfur.

Storage

The Black Doctor is stored in the same way as all grape varieties. A drawer, refrigerator or suspended state - it doesn't matter. The main thing is to observe the temperature and humidity necessary for the berries.
