Why it tastes like this

Why does White Bordeaux taste like that?

A Sauvignon Blanc–Sémillon blend, frequently barrel-fermented, combining citrus freshness with waxy weight.

What this page is and is not

These are the contributors WineHQ can name for White Bordeaux as a category. Every one is a tendency, a convention or a mechanism, and each carries a label saying which. None of it describes how a particular producer made a particular bottle — real practice varies enormously, and a causal account that read as a recipe would be false for a great many of the wines it covers.

The grape

What does the variety bring before anyone does anything to it?

Characteristically very low tannin and high acidity. Commonly associated with gooseberry, grapefruit, passionfruit, cut grass.

Not claiming: That every wine from this variety shows these characteristics. This is the range across the category, and site and winemaking move wines within and beyond it.

Muscadelle

Tendency

Characteristically very low tannin. Commonly associated with orange blossom, grape, honeysuckle.

Not claiming: That every wine from this variety shows these characteristics. This is the range across the category, and site and winemaking move wines within and beyond it.

Sémillon

Tendency

Characteristically very low tannin and medium-plus acidity. Commonly associated with lemon, lanolin, beeswax, honey.

Not claiming: That every wine from this variety shows these characteristics. This is the range across the category, and site and winemaking move wines within and beyond it.

Place and climate

What did the growing season do to the fruit?

Proximity to a large body of water moderates temperature extremes, which is associated with a longer, more even ripening period and a lower risk of both spring frost and extreme summer heat.

Varies: Maritime influence also raises humidity, which raises fungal disease pressure. It is not uniformly an advantage.

Not claiming: That a maritime climate is cool. Maritime describes variability, not temperature.

Winemaking

What decisions were taken between the vineyard and the bottle?

Fermenting white wine in oak rather than steel, which integrates the oak more completely.

Not claiming: That every producer of this style uses this method, or that using it is required.

Blending

Convention

Combining components to make something better than any of them alone.

Not claiming: That every producer of this style uses this method, or that using it is required.

Autolysis of spent yeast releases mannoproteins and other compounds that contribute texture and weight, and savoury bready characters.

Varies: Effect scales with time and is increased by stirring the lees.

Not claiming: That a bready or brioche character proves long lees ageing. Other routes to similar descriptors exist.

Age

What changes after the wine is bottled?

Entry-level Bordeaux Blanc is for its first year or two. Barrel-fermented Pessac-Léognan is a different wine and runs ten to fifteen years, developing a waxy, toasted-nut character from the Semillon.

Not claiming: That a wine of this style will develop these characters. Ageing potential varies by producer, vintage and storage, and most wine is better young.
