Structure (Wine)

Structure (wine) is the framework created by a wine’s acidity, tannin, alcohol, sweetness, body and extract. These elements give the wine shape, weight and persistence on the palate. A structured wine has components that provide definition and support its fruit and flavour; structure is not the same as heaviness or power.

Main elements of structure

• Acidity: provides freshness, tension and balance.
• Tannin: creates grip and a drying sensation, especially in red wines.
• Alcohol: contributes warmth and body.
• Body and extract: contribute weight and texture.
• Residual sugar: adds sweetness and can balance acidity in some styles.

Structure and ageing

Wines with suitable acidity, tannin, concentration and balance may develop over time. Structure alone does not guarantee longevity; fruit quality, producer, vintage, closure and storage conditions also matter. Some lighter wines have excellent ageing potential because of their acidity, while some powerful wines are best enjoyed young.

Examples and food pairing

Barolo and structured Bordeaux are known for firm tannin and acidity. Beaujolais Nouveau is generally lighter in body and tannin and intended for early drinking. The food pairing should match the wine’s structure: tannic reds can work with protein and fat, while lighter wines suit more delicate dishes.

Example: pair a structured Barolo with braised beef, while a lighter Beaujolais can accompany roast chicken or charcuterie.

Chef’s note: structure describes how the wine is built, not whether it is automatically high quality. Look for balance between the components rather than maximum tannin, alcohol or acidity.
