What is Tannins?
Natural compounds in wine that create a drying, astringent sensation in the mouth.
Understanding Tannins
Tannins are polyphenolic compounds found in grape skins, seeds, and stems, as well as in oak barrels used for aging. They create the drying, slightly bitter sensation you feel on your gums and the roof of your mouth when drinking red wine. Tannins also contribute to a wine's structure and aging potential—wines with strong tannins often age better because these compounds act as natural preservatives.
Why It Matters
Understanding tannins helps you choose wines to match your preferences and pair with food. High-tannin wines pair well with fatty, protein-rich foods because the tannins bind to proteins, cleansing the palate.
Examples
