Understanding Tannins in Wine
The Science and Art of tasting wine- The Palate III
Good morning! Let’s dive into the fascinating world of tannins in wine, a structural component that contributes significantly to a wine's character and aging potential.
Understanding Tannins in Wine
As wine enthusiasts, we're often captivated by the nuanced interplay of flavours and textures that emerge with each sip. One of the most intriguing and complex components contributing to a wine's character is its tannins.

Tannins are natural compounds found in grape skins, seeds, and stems, as well as in the oak barrels used for aging, also found in tea leaves, nuts with skin, dark chocolate, some spices like cinnamon and fruits like pomegranates. They’re part of a group of compounds called polyphenols, which contribute to a wine's texture, structure, and ability to age gracefully. When you sip a tannic wine, you’ll often feel a drying or astringent sensation on your palate—this is the effect of tannins at work, binding to proteins in your mouth. Tannins are especially prominent in red wines, which are made by fermenting the juice with the grape skins. This process extracts more tannins, leading to that distinct structure and mouthfeel we associate with reds.
Taming Tannins: Exploring the Sensations of Wine
These naturally occurring compounds can create a diverse range of sensations on the palate, from the robust and structured to the soft and silky. Let's dive deeper into the world of wine tannins and unpack what these varying sensations mean for your drinking experience.
Firm Tannins
Young, bold red wines, such as Cabernet Sauvignon, are often characterized by firm tannins. These structured compounds provide a backbone that helps the wine age gracefully over the years, softening and integrating as time passes. When young, firm tannins can give the wine a bold, robust mouthfeel, but with patience and proper cellaring, they can evolve into a more harmonious and balanced profile.
Soft Tannins
In contrast, some wines like Merlot and certain Pinot Noirs are known for their softer tannic profiles. These gentler tannins add structure and complexity without overpowering the palate. Soft tannins feel smooth and approachable, making these wines enjoyable even when young and often more accessible to a wider range of wine drinkers.
Grippy Tannins
Another category of tannins is the "grippy" variety, which can leave a noticeable drying or "grabbing" sensation on your gums. This is a common characteristic of younger wines that haven't had time to soften and integrate their tannins. Syrah and certain Italian reds, such as Barolo, are prime examples of wines that can exhibit grippy tannins in their youth, eventually mellowing with age.
Silky Tannins
The ultimate evolution of tannins is the silky, velvety texture found in well-aged wines or those made from naturally low-tannin grape varieties. These polished tannins enhance the wine's elegance and refinement, creating a seamless and harmonious drinking experience. Over time, the tannins in wines like Bordeaux and Burgundy can transform into this coveted silky profile.
Understanding the nuances of tannins is a key to unlocking the full potential of wine appreciation. Whether you prefer the bold structure of firm tannins or the velvet-like smoothness of silky tannins, explore the world of wine and let your palate be your guide on this captivating journey.
Tannins and Aging Potential
Tannins play a crucial role in a wine's aging potential. Over time, the tannins in a wine will gradually soften, making young wines with firm, grippy tannins more balanced and integrated as they age. This process allows flavours to deepen and evolve, often revealing complex notes like leather, tobacco, or dried fruits in wines with robust tannic structure. Without sufficient tannins, a wine may lack the structure needed to mature gracefully over decades, which is why tannin-rich wines are often prized by collectors.

However, not all wines benefit from extensive aging; wines with softer tannins may be ready to drink earlier and don’t require the same level of cellaring. Recognizing the tannic structure of a wine can help you anticipate how it might age and when it will reach its peak drinking window.
In summary, tannins are essential in defining a wine’s texture, structure, and longevity. Whether firm or soft, grippy or silky, tannins bring character and elegance, enhancing the wine’s journey from bottle to glass. So the next time you sip a red, take a moment to appreciate the tannins and the role they play in shaping the wine you love.
