What does “tannin” refer to in wine?

• A. Sweetness in wine
• B. Acidity level
• C. Compounds that contribute to structure
• D. Aging potential

Answer: (C)

Tannin in wine refers to the compounds that contribute to the wine's structure. Tannins are polyphenolic compounds that come primarily from grape skins, seeds, and stems, as well as from the oak barrels used for aging. They play a crucial role in the texture and mouthfeel of the wine, providing a drying sensation that can enhance the perception of complexity. Tannins also interact with proteins, which can add to the wine's longevity and aging potential; however, their primary function is to add structure. The compounds that fall under the category of tannins influence how wine will be perceived in terms of its body and weight. They are essential for the balance of a wine, working alongside acidity and sweetness to create a harmonious profile. A wine with well-integrated tannins will often have a smoother mouthfeel, while high tannin levels can result in a more robust and astringent quality. While options relating to sweetness, acidity, and aging potential each have their significance in wine, they do not directly describe what tannins are or their primary role in the composition of a wine. Thus, understanding tannins as structural compounds is fundamental in wine tasting and evaluation.
