Bouteillan noir

The white Provençal grape Colombaud (not to be confused with the Cognac and South African wine grape Colombard) was once thought to be a white berried color mutation of Bouteillan noir but research conducted by Linda Bisson of the University of California, Davis shows that while the two grapes are likely related, one is not a color mutation of the other.

[2] Bouteillan noir is a late budding and ripening variety that is highly susceptible to coulure which leads to very variable yields each vintage.

Other viticultural hazards that the vine is susceptible to include botrytis bunch rot and powdery mildew.

[1] Ampelographers believe that Bouteillan noir is closely related to Provençal grape Colombaud but unlike Pinot blanc/Pinot noir and Grenache blanc/Grenache, the two grapes are distinct varieties and not color mutations of one or the other.

[1] Over the years Bouteillan noir has been known under a variety of synonyms including: Bouteillan a Gros Grains, Boutelion noir, Cargomuou, Cayau, Esfouiral, Esfouiras de Roquemaure, Fouiral (in the Hérault department), Moulas (in the Vaucluse department), Petit Bouteillan, Plant de Psalmodi, Psalmodi noir, Psalmody, Sigotier and Sigoyer (in the Alpes-de-Haute-Provence department).

The Vaucluse region where Bouteillan noir was noted to be widely planted in the early 18th century.
Despite sharing several synonyms, Bouteillan noir has no known relationship to the Provençal wine grape Calitor (pictured) .
