Definition: Tannins are naturally occurring polyphenolic compounds found in grape skins, seeds, and stems, as well as in oak barrels used for aging wine. They contribute to the wine's bitterness and astringency, creating a drying sensation in the mouth.
Source: Tannins come from various parts of the grape and the winemaking process. Skin contact during fermentation, the inclusion of seeds and stems, and aging in oak barrels can all introduce tannins into the wine.
Role in Red Wines: Tannins are more prevalent in red wines due to the extended contact with grape skins during fermentation. This process extracts more tannins, giving red wines their characteristic structure and complexity.
Aging Potential: Tannins play a crucial role in the aging potential of wine. High-tannin wines often have a longer aging potential, as the tannins soften and integrate over time, leading to a more balanced and complex wine.
Texture and Mouthfeel: Tannins contribute to the mouthfeel of wine, providing a textural element that can range from silky and smooth to rough and drying. This astringency can balance the wine’s fruitiness and sweetness.
Balance with Acidity: The interaction between tannins and acidity is essential for the overall balance of the wine. A well-balanced wine will have tannins that complement its acidity, enhancing its structure and drinkability.
Food Pairing: Tannic wines pair well with rich, fatty foods. The tannins can cut through the fat, cleansing the palate and enhancing the flavors of both the wine and the food. Common pairings include red meats, aged cheeses, and dishes with creamy sauces.
