Trivia: What characteristic do tannins give red wines?
Dryness
Color
Sweetness
Bubbles
The correct answer is Dryness
So why is this answer correct? : Tannins give red wine that bitter, sometimes astringent, feeling in the mouth that so many red wine lovers enjoy. They are transferred to the grape juice when it comes into contact with the skins, stems, and seeds early in the winemaking process. Because white wine barely touches the skins during the winemaking process, it has much lower levels of tannins, resulting in a sweeter wine. Tannins can also come from the wooden barrels used to age the wine.
