What Are Tannins in Wine?

Tannins are compounds found in the skins and seeds of grapes used to make wine. They give the wine a dry, puckering finish and also contribute to its color and complexity. Tannins are an important aspect of wine heritage, often providing a subtle reminder of the region or heritage from which the grapes were sourced. They are responsible for the bitter taste that some red wines can have and can also provide a unique flavor profile, as different grape varieties will impart tannins with varying levels of intensity. Tannins also act as natural preservatives, helping to ensure that wines age gracefully and remain drinkable over time.

Tannins provide structure and balance to a wine, making it taste fuller-bodied and more age worthy. They also act as a natural preservative, helping to prevent spoilage and oxidation. Tannins are found in the skins, seeds and stems of wine grapes, and give wine its characteristic astringency and bitterness. They can be harsh on the palate if wine has been aged for too long, so winemakers must find a balance between tannins and other elements like acidity or sweetness to create a wine that is harmonious and pleasant. Careful wine making techniques can also be used to reduce the amount of tannins in wine, allowing wine-makers to craft a variety of styles according to their taste. Ultimately, tannins are an integral part of wine-making and are essential for creating truly remarkable wines.

In addition to imparting flavor, tannins create a sensation of bitterness or astringency on the tongue which can be expressed as a “gripping” or “gritty” sensation. This is due to the polyphenols in tannin molecules which bind with proteins in saliva, creating an unpleasant sensation on the tongue Thereafter, tannins in wine can have a significant impact on the wine drinking experience. They impart unique flavors, as well as a bitter or astringent sensation on the tongue. This “gripping” or “gritty” feeling that wine tannins create is due to polyphenols in tannin molecules which bind with proteins in saliva. In wine, tannins add complexity and balance of flavor to its character.

Conclusion

In summary, tannins are complex molecules found in grape skins, stems, and seeds. These molecules provide astringency and bitterness to wines. They are important for giving depth and structure to wine, allowing it to age gracefully over time. When tasting a wine, tannins should be balanced with the other components like acidity, sweetness, and body. Overall, tannins can be influential in dictating the character of a wine and should be considered when making judgments about its quality.
