How to taste: Tannin
Tannin is a compound in wine that mostly comes from the skins and stalks of a grape, so it is most evident in wines that have been macerated with the skins and stalks. White wine doesn’t go through maceration, so tannins won’t be present. In wine this feels as the drying, slightly bitter feeling on your gums. To assess it, focus on that feeling, the higher the intensity, the higher the tannin level.
