Tannins in Whiskey - The Subtle Power behind Taste and Mouthfeel
When wine and whisky connoisseurs talk about the structure, depth and complexity of a drink, tannins are often a significant part of the conversation. But what exactly are tannins, and how do they affect our experience of different drinks?
What are Tannins?
Tannins are naturally occurring compounds found in a variety of plants, including grapes, tea leaves, and various types of wood. These compounds are polyphenols that have the ability to bind to proteins and other molecules in the mouth.
The Influence of Tannins
Mouthfeel: A high concentration of tannins can give a feeling of roughness or dryness in the mouth. This is the sensation that makes the mouth feel as if it is contracting when drinking a particularly tannin-rich wine or tea.
Flavor: Tannins can add some bitterness and astringency to beverages, which can contribute to the depth and complexity of flavor.

Color: In wines, tannins can contribute to the stability and intensity of color, especially in red wines.
Tannins in Whiskey
While tannins are often associated with wine, they also play a role in the world of whisky. Tannins enter the whisky from the wooden barrels during the aging process. Depending on the previous contents of the barrel, the type of wood and how long the whisky has been aged, the level of tannins can vary.
Age and Tannins: In general, older whiskies will have a greater concentration of tannins as they have had more time to interact with the wood.
The Importance of the Barrel: Tannin content can also vary depending on the type of barrel. For example, a sherry barrel will often contribute more tannins than a bourbon barrel.
Conclusion
Tannins are powerful little compounds that have a big impact on our drinking experience. They are responsible for many of the subtle nuances we love in both wine and whisky. Understanding tannins and their effects can enrich our understanding and enjoyment of many beverages, from the deepest red wine to the most complex single malt whisky.
