Unraveling the Mystery of Wine Tannins: Understanding Their Role and How to Control Them
Wine tannins can be mysterious to most novice wine drinkers. However, they play a crucial role in determining the quality, flavor, and structure of a wine. In this post, we’ll take a closer look at wine tannins, their role, and how to control them.
What Are Wine Tannins?
Tannins are naturally occurring polyphenols found in various plant parts, including grape skins, stems, and seeds. In wine, tannins contribute to its texture, astringency, and bitterness. Tannins are also responsible for giving red wine its characteristic color.
The Role of Tannins in Wine
Tannins contribute to the structure and texture of wine, making it more complex and flavorful. They create a puckering sensation in the mouth and can be described as dry, rough, or gritty. High-tannin wines, such as Cabernet Sauvignon or Syrah, need time to age and soften, while low-tannin wines, such as Pinot Noir, can be enjoyed young.
Controlling Wine Tannins
Winemakers have several methods to control tannin levels in wine. One of the most critical factors is the grape variety, as some grapes have higher levels of tannins than others. For example, Cabernet Sauvignon grapes have thicker skins and seeds, resulting in wines with higher tannin content.
Another way to control tannins is during the winemaking process. The time spent macerating the grape juice with the skins, stems, and seeds can affect the tannin levels. Additionally, the choice of aging vessel, such as oak barrels, can impact the amount of tannins in the wine.
The Bottom Line
Understanding tannins and their role in wine is crucial for any wine lover. By knowing how to control tannin levels, winemakers can create wines that are both enjoyable now and age-worthy. So next time you take a sip of your favorite red wine, think about the tannins and how they contribute to its overall quality.
