Yes, in very hot producing areas outside Australia, the higher the alcohol content of the brewed red wine, the higher the sugar content of the grape juice. The higher the sugar content of the grape means sufficient sunshine, high accumulated temperature, high accumulated glucose content and abundant rainfall during the grape growing period, so the alcohol content of the wine is one of the indicators to judge the quality of the wine.

Extended data

Domestic planting conditions are not the most suitable for grape growth, such as Bordeaux, France. The alcohol content of sugar accumulated in grapes is generally around 9- 10, so sucrose is usually added to improve the sugar content.

Domestic wine management is not standardized, and the alcohol content is between 1 1, 5- 12.

There are also some varieties abroad, and the brand alcohol content is higher, as high as 15.

The shelf life of some imported wines is mostly 10 years (a few are 15 years or 20 years), because the relevant laws in China require that the shelf life be indicated on the label. Since June 65438+ 10/day, 2006, the General Rules for the Labeling of Prepackaged Drinks, which was officially implemented in China, stipulates that the shelf life of wines and other alcoholic beverages with alcohol content exceeding 1 0% can no longer be marked.
