Tannins
Polyphenolic compounds creating astringent, drying sensation.

Tannins are naturally occurring polyphenolic compounds found in grape skins, seeds, and stems that create a drying, astringent sensation on the tongue and gums. They are one of the primary structural components of red wine, contributing to its texture, aging potential, and food-pairing characteristics.
What Tannins Feel Like
Tannins produce a tactile sensation rather than a flavor. The feeling is similar to:
- Drinking oversteeped black tea
- Biting into an unripe banana peel
- The dry, puckering sensation after eating walnuts
Where Tannins Come From
- Grape skins — Primary source; longer skin contact = more tannins
- Seeds and stems — Harsher tannins if extracted
- Oak barrels — Wood tannins from aging
Identifying Tannins in Blind Tasting
When tasting blind, assess tannins by:
- Running your tongue along your gums after swallowing
- Noting if your mouth feels dry or "grippy"
- Rating from silky (low) to astringent (high)
High vs. Low Tannin Wines
| High Tannin | Low Tannin |
|---|---|
| Cabernet Sauvignon | Pinot Noir |
| Nebbiolo | Gamay |
| Syrah | Grenache |
| Tannat | Barbera |
Why Tannins Matter for Pairing
Tannins bind with proteins and fats, which is why tannic wines pair well with:
- Fatty cuts of beef (ribeye, brisket)
- Rich cheeses (aged cheddar, Parmesan)
- Dishes with umami (mushrooms, soy-based sauces)
