Italian winemakers managed to get a fragrant light wine with honey notes from the berries of this variety. Breeding work carried out by the Soviet scientists P.P. Blagonravov, E. B. Ivanova and P. V. Gorobets made it possible to increase the yield of the variety and made it possible to grow it on the territory of the North Caucasus and the former Soviet republics.

In 1970, he passed state tests, and since then has been successfully cultivated in Russia.

The best wines from the berries of this variety are produced by Italy and France, however, its own wine Pinot Grigio is produced by Germany, the USA, Australia, Chile, Russia and many other countries. Pinot Gris is a cloned main variety cultivated in Switzerland.

Bush and shoots

The variety is distinguished by a significant growth of shoots and a developed root system. Annual shoots are light brown, with shortened internodes and darker nodes. With a strong growth, the bush needs pruning. The crown of young shoots is strongly pubescent. In the first three years after planting, the bush is especially demanding to comply with agrotechnical growing conditions.

Yield

The variety has an average yield. There are about 52% of fruitful shoots on the bush. When grown industrially, it gives about 9 tons per hectare. For a good harvest, you need: suitable soil, no drafts and timely treatment against pests and diseases. The low yield is more than offset by the excellent taste of the resulting wine.

Grows well in sunny, elevated or well-drained areas with neutral or alkaline soil. The distance between bushes in a row and aisles for Pinot Grigio is about one meter. Planting hole - 80x80 centimeters.

Before planting, the roots are soaked in water for 24 hours, pruned if necessary and treated with a clay talker. If the soil is not too fertile, humus is added to the bottom of the hole. The soil in the hole is poured with a slide, a seedling is carefully placed in the center and the roots are evenly spread.

grape planting

Important: in the first 3 years, this grape variety requires particularly gentle care. After planting, the soil is compacted and the plant is watered.

Soil loosening

Seasonal disease prevention

Since the variety is susceptible to mildew and mildew diseases, the plants should be regularly sprayed. This is done with a Bordeaux mixture or fungicides (Horus, Topaz, Strobi). After the formation of the ovary, during the period of berry filling, spraying is not carried out.

Autumn processing is carried out before the grapes are sheltered for the winter to prevent the preservation of spores and the development of diseases in the next season.

Bunch care

They are protected from birds by pulling on a metal mesh. To protect against wasps, poisoned bait is hung in the vineyard, wasp nests are found and burned. If the bunches are affected by diseases, they are destroyed in a timely manner in order to prevent the spread of the disease.
