If you’ve ever taken a sip of red wine and felt your mouth suddenly go dry—or noticed a bold bitterness that lingers on your tongue—chances are, you’ve just encountered tannins. They’re one of the most misunderstood (and underappreciated) elements of wine. So, what are tannins in wine, exactly? In simple terms, they’re the compounds that affect a wine’s structure, texture, and aging potential—and once you understand how they work, you’ll quickly level up your wine game.
Whether you’re stocking your bar cart or choosing a bottle for your next dinner party, understanding tannins can help you make more confident, flavor-forward choices. So let’s break it down without all the wine snob jargon.

🌱 What Are Tannins, Really?
Tannins are naturally occurring compounds found in:
- Grape skins
- Seeds
- Stems
- Oak barrels used for aging
They belong to a larger group of compounds called polyphenols, which are also found in tea, dark chocolate, and even walnuts. In wine, tannins are extracted during the fermentation and aging process, especially in red wines where the juice is fermented with the skins for longer.
👅 What Do Tannins Taste Like?
Tannins don’t have a flavor in the traditional sense—they affect texture more than taste.
Imagine sipping a bold red and your mouth feels almost chalky or drying. That’s the tannin effect. They bind to the proteins in your saliva, which creates that astringent, mouth-drying sensation. The more tannic a wine, the more intense this feeling.
High-tannin wines typically taste:
➡️ Bold, structured, and slightly bitter
Low-tannin wines feel:
➡️ Smooth, soft, and fruit-forward
🍷 Are Tannins Only in Red Wine?
Nope! While tannins are more concentrated in red wine (because of extended skin contact during fermentation), they’re not exclusive to it.
You’ll also find tannins in:
- Rosé (moderate amounts)
- Orange/skin-contact white wines
- Certain whites aged in oak barrels
- Natural teas + foods like dark chocolate and nuts
🚫 Common Tannin Myths – Debunked
❌ Myth #1: Tannins = Bad Wine
Not true! Tannins are an essential building block of wine. When balanced well, they enhance structure and aging potential.
❌ Myth #2: Only Sommeliers Care About Tannins
Wrong again. If you want to know why you like certain wines over others—or how the wine will taste a few years from now—tannins play a major role.
❌ Myth #3: Tannins Always Taste Bitter
Tannin levels vary widely. Some are firm and drying, while others are silky smooth. It’s all about balance.
