Sweetness and Alcohol Levels

[Thomas]

Bostongirl, the higher the alcohol, the sweeter the grapes were at ripening, but not the sweeter the wine.

Lower alcohol interprets into potentially sweeter wine, since the alcohol in wine is created by yeast eating sugar. If the yeast are allowed to eat all the sugar, the wine is not sweet; if the yeast eat some of the sugar, the wine is as sweet as the sugar that remains.

Alcohol being fermented sugar, high alcohol wines might taste sweet even when they are dry.
