Tannins in Wine – Why It Is Important

By

This is a detailed and easy to comprehend guide on Tannins, one of the key traits used to characterize wines.

Let’s get started.

What is Tannins?

Tannins are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds.

They are widely distributed in plant tissues.

They are found in foods such as green tea, dark chocolate, walnut skins, grape skins, beer, fruit juices, etc.

Tannins give these beverages their characteristic taste and mouthfeel. Tannins are mainly used for their preservation properties.

Tannins and Wine

Tannins are one of the most important aspects of wine. They contribute to the astringency, body, and age-ability of a wine. Tannins are found in the skins and seeds of wine grapes. The longer a grape skin is in contact with the juice during fermentation, the more tannins will be extracted from it.

Why are tannins important in wine?

A few reasons –

  • Tannins add structure and stability to a wine, helping it to age gracefully. They can also make a wine taste more full-bodied and complex.
  • Tannins help in stabilize the wine and protect it against oxidation.
  • Tannins are also considered to be an important source of wine’s health benefits too.

However, too much tannin can make a wine taste bitter and harsh. This is one of the key aspects which goes against the presence of tannins in a wine.

The ideal amount of tannin depends on personal preference. Some people enjoy the feeling of astringency that tannins provide. Others find it unpleasant.

If you’re not sure whether you like wines with high levels of tannin, start by trying aged wines, which tend to have less tannin than younger wines.

As wines age, their tannins mellow and become more integrated into the overall flavor profile.
