This question requires certain conditions. For red wines from the same production area of ??different years, the same winery of different years, or the same vintage of different production areas, the higher the alcohol content, the better.

The process of wine making is a process in which yeast eats the sugar in the grape juice and metabolizes it into alcohol. Generally, 18 grams of sugar will be converted into one degree of alcohol. Therefore, for wines from the same production area or different vintages from the same winery, the one with higher alcohol content will be of higher quality. Because the high sugar content proves that the production area is relatively hot during the year, the temperature difference between morning and evening is large, and the sugar content is accumulated high, so the alcohol content of the wine is high. This can be said that the vintage is good, so the high alcohol content is good and the quality is good. If they are produced in different production areas in the same year, it depends on whether they are both New World production areas or Old World production areas. At the same latitude, which one has higher alcohol content will have better quality. There are high limits to quality based on alcohol content, and you can’t just look at the alcohol content. For example, in a particularly hot production area, this would not make sense.
