Cultivation of black grapes

The cultivation of black grapes, as for the white grape, is particularly laborious, it follows the whole natural cycle of the vine, which goes from winter dormancy to spring production and taking care of it requires passion, patience, and experience and cannot absolutely be improvised.
The soil, must be free from weeds, practicing periodic interventions for cleaning and irrigation must be carried out in the event of drought, paying particular attention to the rainy season because too much water spoils the production, while fertilization must be carried out in the post-harvest period. The trimming of the vineyard, or the removal of the Apices, has the fundamental purpose of increasing the influx of sugars towards the bunches and must be carried out towards the month of June, at most towards the end of August.

Cultivation for the cultivation of black grapes

Grapes in general is an extremely adaptable plant, it must be placed in an area where it is hit in full by the sun, which is fundamental in the maturation of the berry and its sugar content. Unfortunately, for this plant too rigid temperatures or below -15 degrees centigrade or even late frosts below -5 degrees can be dangerous, they could lead to the loss of the entire vineyard; for this reason it is not possible to cultivate it, above 1000 meters of altitude.
The vine loves the land with a PH ranging from 6.5 to 7.5, clay or sandy soils are not good, while stony soils are particularly suitable. In order to begin its cultivation, barbettes must be grafted at least two years old, in the autumn period and later by the end of March.

Black grapes: The harvest or the harvest of black grapes

The difference between harvesting and harvesting is in the different destination of the bunch, that is: the first is table grapes, while the second is destined for the production of wine. The ideal time to start this phase is influenced by the weather and environmental conditions: the higher the altitude, the earlier the grapes ripen and before they are harvested, in addition not all the species ripen in the same period, the one that generally takes less time and it is black grapes.
The harvest is a delicate process, in fact it is preferable to carry it out by hand even though it is longer, but it allows the best selection of the bunches, since a small quantity of bad grapes can ruin the entire production; this method is often used for quality grapes destined for the production of fine wines such as champagne.
