Clairette blanche

Also known as Clairette, Clairette B

Clairette blanche is an old white Vitis vinifera variety of southern France. In the French catalogue it is officially called Clairette B, while “Clairette blanche” helps distinguish the grape from wines and appellations that use Clairette in their names. It ripens late, can produce fairly alcoholic wines, and naturally gives relatively little acidity. Those traits explain its long use in warm Mediterranean vineyards, but also why harvest timing, blending, and oxygen control matter.

The variety is easy to overlook because it appears in several roles rather than one signature wine. It can be bottled alone in parts of the Languedoc and southern Rhône, contribute shape and regional character to blends, or support sparkling wines in the Diois. Its weaknesses are part of that history: growers and winemakers have repeatedly used place, picking decisions, and other grapes to make its broad, oxidation-prone material useful.

History and identity

Plantgrape identifies Clairette as Provençal in origin. The precise first appearance of the vine is not documented, so claims that it was introduced by the Romans should be treated as historical tradition rather than established varietal history. An Australian Wine Research Institute overview places the variety in the south of France and records it by the late sixteenth century. That is firm evidence for its early modern presence, not proof of an unbroken vine from antiquity.1.

Its historical importance is regional and practical. Clairette was planted widely across southern France and was used both alone and as a blender in Provence, the Languedoc, and the Rhône. The Languedoc appellation account connects the grape with white wines from the Hérault valley that were exported under the name “picardan” in the medieval and post-Renaissance periods. This is useful evidence of a local white-wine trade, though the old commercial name and the modern variety should not be treated as automatically identical in every historical record.2.

Plantings in France fell substantially during the second half of the twentieth century, from 14,099 hectares in 1958 to 2,115 hectares in 2018 in the Plantgrape series.3. Plantgrape, “Clairette B,” varietal record, accessed 7 September 2026. The decline does not make Clairette an obsolete grape. Surviving appellations and renewed interest in regional varieties have kept its distinct uses visible.

Viticulture

Clairette is vigorous and late-ripening. Plantgrape places its maturity about four weeks after Chasselas, a French reference variety used to compare phenology. It performs better on poor, dry, often calcareous ground than on fertile sites, and short pruning and careful shoot removal help contain its vigour. The vine is relatively less sensitive to powdery mildew and grey rot than to some other diseases. Peter Dry reports susceptibility to downy mildew and bunch rot. Wind, season, water supply, and crop level still alter the outcome, so these remain tendencies rather than a fixed recipe for every vineyard.1. Institut français de la vigne et du vin, INRAE & Institut Agro Montpellier, “Clairette B”, Plantgrape varietal record, edited 6 September 2026, accessed 7 September 2026; Peter Dry, “Clairette”, Australian Wine Research Institute, Wine & Viticulture Journal, winter 2019.

Late ripening in a warm climate creates a linked harvest decision. Waiting can build sugar and alcohol while acidity remains limited; picking earlier can protect freshness but may give less ripe flavour and weight. Clairette’s official varietal record describes its wines as relatively low in acidity and often apple-scented, with occasional bitterness at the finish. The result is not necessarily dull: dry sites, an earlier harvest, sparkling-wine production, or a blending partner can change the balance. But the grape rarely supplies a firm acid line by itself in the way that a naturally high-acid variety does.

Wine character and oxidation

Clairette’s wines can be moderately full and alcoholic, with aromas commonly associated with apple, fennel, lime blossom, apricot, or peach. These descriptors vary with ripeness and production, so they are more useful as a small map of possibilities than as a tasting checklist. Low acidity makes the wine feel broad when alcohol and ripeness rise, while a touch of bitterness can add length or counterweight.

Oxidation is a separate but important vulnerability. The Australian Wine Research Institute describes Clairette as very prone to oxidation during vinification. Oxygen can consume fresh aromas and alter a white wine’s colour and flavour; the speed and severity depend on the must and wine, sulfur dioxide, temperature, oxygen exposure, and later storage, not on the grape name alone.4. Mario Gabrielli et al., “Oxygen-induced faults in bottled white wine: A review of technological and chemical characteristics”, Food Chemistry 348 (2021), article 128922; Dry, “Clairette.” Clairette’s low acidity can make the loss of freshness more obvious, but it is not sufficient evidence that acidity itself causes the oxidation.

This combination helps explain why traditional Clairette wines were not always intended for long, reductive storage. Some were made for early drinking, while over-ripe fruit could be used for rancio-style wines in the Languedoc. The latter is a deliberate oxidative tradition in some local accounts, not a reason to treat every oxidized bottle as successful rancio. A fresh style calls for sound fruit, a controlled harvest, and protection from avoidable oxygen; an oxidative style requires a different intention and degree of control.

Regional roles

Clairette remains particularly associated with the southern Rhône and the Diois. Inter Rhône lists it among the authorized grapes of many southern appellations. Clairette is a principal variety of white Gigondas.5. Ministère de l’Agriculture et de la Souveraineté alimentaire, “Cahier des charges de l’appellation d’origine contrôlée « Gigondas »”, homologated 10 December 2024, section V, published 19 December 2024. In the southern Rhône it may be bottled alone, as in Clairette de Bellegarde, but more often contributes to blends. Its relatively soft acidity, late-ripening Mediterranean character, and light bitterness can broaden a white blend; Grenache Blanc is a useful comparison because it often plays a similarly generous structural role, though the two grapes are not interchangeable.

In the Languedoc, Clairette du Languedoc is a single-variety appellation created in 1948. Its range includes dry and gently sweet wines, while a smaller rancio tradition remains.6. Institut national de l’origine et de la qualité, “Clairette du Languedoc rancio”, accessed 7 September 2026. The existence of a named appellation does not mean all Clairette from the region tastes alike: harvest date, sweetness, vessel, and oxygen exposure lead to different results.2. Syndicat des vins de l’AOC Languedoc, “AOP Clairette du Languedoc”, accessed 7 September 2026.

The Diois gives Clairette a second, sparkling identity. Under the adopted Clairette de Die specification, wines made by the “méthode ancestrale” are led by Muscat Blanc à Petits Grains, with Clairette among the permitted complementary grapes. Other wines in the appellation are made solely from Clairette by second fermentation in the bottle. Crémant de Die likewise keeps Clairette in the region’s sparkling tradition. In these wines, acidity, carbon dioxide, sweetness, and lees contact alter the perception of freshness, so the grape’s naturally soft acid structure does not make sparkling production contradictory.7. Ministère de l’Agriculture et de la Souveraineté alimentaire, “Cahier des charges de l’appellation d’origine contrôlée « Clairette de Die »”, homologated 9 December 2024, section V, published 19 December 2024.

In the cellar

The most consequential choice is usually the harvest and the degree of oxygen protection. Earlier picking can preserve a fresher balance; gentle handling and appropriate sulfur-dioxide management can limit oxidation, although the exact regime depends on fruit condition and the intended style. Blending with a higher-acid partner such as Piquepoul Blanc is a documented French response to Clairette’s low acidity. Fermentation and maturation in a neutral vessel can keep the focus on the grape, while deliberate oxidative handling can develop a rancio style. Neither approach is automatically better; each must match the wine’s purpose.

Sparkling production adds another route to balance. In traditional-method sparkling wine, the second fermentation and dissolved carbon dioxide change texture and freshness, while the base wine still has to arrive with enough acid and stability for the method. Clairette’s continued presence in the Diois therefore reflects adaptation, not a contradiction of its still-wine profile.
