Increasing the sugar content of grapes requires certain knowledge and skills.
Expert of the online publication BelNovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh shared recommendations that will allow you to achieve your goal.
First of all, it is worth remembering that choosing the right grape variety is of great importance for obtaining sweet berries – of course, it must have a high sugar content.
These are varieties such as Riesling, Cabernet Sauvignon, Merlot, Chardonnay, Pinot Noir, Sauvignon Blanc, etc.
In addition, the vineyard needs to be provided with optimal conditions in the form of a warm and sunny place with sufficient moisture.
If weather conditions are less than favorable, winegrowers resort to a method called “clarification of the bunches.”
This method involves removing some of the leaves around the bunches before the grapes begin to ripen. It is important to do this gradually, removing a few leaves at a time, as removing all the leaves at once can cause the bunches to get sunburned.
Also, to increase the sugar content of berries, you can remove excess shoots, remove side shoots and pinch the tops of shoots that have reached the top wire.
These radical measures are most often used in cold summers, when the grapes do not have enough warmth to ripen.
