What is mouthfeel?
Quick answer
Mouthfeel is the physical sensation wine creates in your mouth — its weight, texture, and body. It's the difference between skimmed milk and double cream. A full mouthfeel comes from alcohol, glycerol, tannins, and dissolved solids working together. When a wine fills your mouth with rich, velvety texture, that's impressive mouthfeel.
Detailed answer
Mouthfeel is one of those wine concepts that clicks the moment you experience it. Pour yourself a light Muscadet and a big Châteauneuf-du-Pape, taste them side by side, and you'll instantly feel the difference. One's like water; the other's like velvet.
What creates that sensation of weight and richness? Several things. Alcohol is a big one — higher alcohol means more viscosity. That's why a 14.5% Napa Cabernet feels fuller than an 11% German Riesling. Glycerol, a natural byproduct of fermentation, adds an oily smoothness. Residual sugar, tannins, and various dissolved compounds (collectively called 'extract') all contribute too.
Tannins play a fascinating role. Fine, ripe tannins create a velvety, almost creamy texture. Harsh tannins do the opposite — they dry your mouth out and make the wine feel astringent rather than full. This is why winemakers obsess over tannin quality, not just quantity.
Acidity is the counterbalance. It cuts through richness and adds freshness, like squeezing lemon on a rich dish. A wine with lots of body but no acidity feels flabby and heavy. A wine with high acidity but no body feels thin and sharp. The magic happens when both are in balance — the wine feels simultaneously rich and refreshing.
Sommeliers typically describe body on a three-point scale: light (think Muscadet, Vinho Verde), medium (Chianti, Côtes-du-Rhône), and full (Barolo, Châteauneuf-du-Pape, Barossa Shiraz). This matters for food pairing: match the weight of the wine to the weight of the dish, and you're halfway to a perfect pairing.
| Component | Contribution to mouthfeel | Typical range | Sensory effect |
|---|---|---|---|
| Ethanol | Viscosity, warmth | 11-15% ABV | Roundness, fullness |
| Glycerol | Smoothness | 3-15 g/L | Oily, soft texture |
| Tannins (reds) | Texture, grip | 1-4 g/L | Velvety or astringent |
| Residual sugar | Density, sweetness | 0-200+ g/L | Weight, richness |
| Polysaccharides | Roundness | 0.5-1.5 g/L | Silky, coating |
| Acidity | Counterbalance (tension) | 4-9 g/L tartaric acid | Freshness, lift |
