Traditionally, grapes are considered a heat-loving culture, which has not very good winter hardiness. The Northern sweet grape belongs to such frost-resistant types of cultivated grapes.

The origin of the variety is not known exactly. According to one version, Ivan Vladimirovich Michurin himself was its author. Indeed, at one time, the famous breeder worked a lot to promote grapes to the north. He received varieties:
- Northern white
- Korinka Michurina
- Russian Concord
- Seedling Malengra
- Black sweet
However, there is no information about a grape with the name northern sweet among the Michurin varieties. Further study of the issue of the origin of the variety suggests that in 1936, working on the breeding of frost-resistant varieties, Michurin's followers, breeders Ya. I. Potapenko, in collaboration with E.I. Zakharova crossed the Michurin Seedling Malengra with the Amur grapes.
The result of this work was the Severny variety. Perhaps later, the name of the word sweet was added to the name of one of the seedlings of this variety.
Perhaps, in addition to the Michurin varieties, varieties from the Pinot group were also used in its breeding, most likely Black Pinot or Pinot Noir. Since the bunches of northern sweet are similar in shape to the bunches of these famous wine varieties. Some lovers also note the similar taste of the berries.
Pinot itself does not have good yields in a cool climate, but if Amur grapes or another local variety were used in breeding work with them, then not only a frost-resistant, but also a fruitful form could well have turned out. There is a version that Northern Sweet is an autochthonous technical variety. The famous winegrower M.F.Abuzov in his books gave a description of the Northern Sweet variety.
Northern sweet, variety description
Shoots of northern sweet grapes are distinguished by their great vigor. The vine is characterized by good maturity. This provides the bushes with high winter hardiness. Northern sweet tolerates low temperatures up to -30 degrees. Northern Sweet is a medium-ripening technical variety.
For the berries to ripen from the moment of dissolving the buds, the variety needs about 130 - 135 days. In the southern regions, harvesting begins in late August - early September. In the conditions of the Moscow region and more northern regions, the berries ripen by September 15-20.
The brushes are moderately firm, weighing 80 to 120 grams. The berry is round. The weight is not more than 1.5 g, although under favorable conditions it can be 2 g. The color of the berries is dark blue or blue-violet, with a waxy bloom on the skin. The skin is firm but rather thin. In the southern regions, the sugar content is high, from 23 to 25%.
With an acidity of 6-7 g / l. In more northern regions, the acidity can be higher and reach 8-11 g / l, while the sugar content is not more than 19-21%. The pulp is juicy, sweet and sour, the taste is quite harmonious. The separation of the seeds from the pulp is satisfactory. The advantages of the northern sweet variety include:
- frost resistance
- good ripening of shoots
- high resistance to powdery mildew and other diseases
As a disadvantage, it should be noted the deterioration of not only taste, but also yield with a lack of water. Despite the fact that many amateur winegrowers note the ability to withstand frosts down to -36, it is still better to grow under light cover or lay vines on the ground in the northern regions, as well as in the Urals and Siberia. They will be covered by the snow that has fallen.
The harvest of northern sweet berries can be a good base for aged homemade wine with a rich pleasant taste. The climate in most regions of the country is characterized by rather short and cool summers, few sunny days and low negative temperatures in winter. To get a harvest in regions with such a climate, you need to know about some of the secrets of growing northern sweet grapes.
Features of growing Northern sweet
If a grape seedling was purchased in early spring, then you should not rush to plant it in the ground. It is necessary to wait not only for thawing, but also for the warming up of the soil at a depth of 0.5 - 0.6 meters. As a rule, this does not happen earlier than the last days of May - the first ten days of June.
Until that time, the seedlings of the Northern Sweet must either be dug in or containers should be placed against the southern wall, covering them from the wind. It is believed that the further north the grapes grow, the more severe the climate and weather conditions, the healthier the berry is and the tastier the wine or juice made from it. However, in order to grow Northern sweet grapes in such unfavorable conditions, you need to know some agrotechnical subtleties.

To ensure good and uniform heating of the soil at an air temperature of 18 - 22 degrees, you need to arrange a trench along the row of grapes on the southern side of the plantings. This will ensure faster thawing of the earth in spring, drainage of melt water and warming up the soil to the required depth.
If it is not possible to arrange such a trench, you can plant grapes in bulk ridges. The height of such ridges should be about 0.8 m, the direction is from west to east. This placement adds 1-2 degrees of heat. In addition, the processes of laying fruit buds are more intensive. Planting in ridges avoids waterlogging with excess precipitation and a more even distribution of sunlight.
However, this method also has a disadvantage. This is, first of all, the intensive consumption of nutrients by the vigorous shoots of the Northern Sweet and their additional washing out of the soil by rain. To slow down these processes, the soil must be enriched with substances useful for grapes.
For this, in the second half of May, about 10 kg of rotted manure is introduced under each grape bush. It is laid out under bushes without embedding in the ground. This technique is especially effective when growing grapes in ridges. Manure spread out on top of the ridge will provide the bush with the required amount of organic matter, first through the lower row of leaves, and after warming up the soil, even through the roots.
Many growers believe that if the plot yielded 10 tons of grapes, then the next season the same amount of manure should be added to the land. For the rest, the cultivation technique of this variety in conditions of unstable weather and a temperate climate does not differ from the cultivation of other technical varieties.
