Grape Sugar Content

Vitis vinifera L.

A key indicator of crop quality, reflecting the concentration of glucose and fructose in berry juice, which determines harvest timing and the potential of future wine.

In the reference 126 varieties crop Common grape vine, where this is mentioned in the description.

The sugar content of grape berries varies between 12–30% depending on the variety, climatic conditions, and agricultural practices. For high-quality wines, target values are considered to be in the 20–24% range, while values below 18–20% are often insufficient for complete fermentation without additional adjustment.

Monitoring sugar levels, along with acidity and pH indicators, allows the agronomist to precisely determine the optimal harvest start date. The rate of sugar accumulation depends on insolation and thermal conditions, as well as agrotechnical factors such as water management and the level of crop load per vine.
