Final answer:
Dry wines have a low sugar content, typically less than 10 grams per liter. This is achieved through the fermentation process.
Step-by-step explanation:
In order to be classified as a dry wine, the sugar content must be relatively low. Typically, dry wines have less than 10 grams of sugar per liter.
This low sugar content is achieved through the fermentation process, where yeast consumes the grape sugars and converts them into alcohol.
Dry wines are considered opposite to sweet wines, which have a higher sugar content and can taste more sweet or syrupy.
