Grape

Melon de Bourgogne

Melon de Bourgogne is a white Vitis vinifera variety whose public identity is closely tied to Muscadet, the group of appellations around Nantes. That association can obscure the grape itself: the name on the bottle usually identifies the place and wine category, while the variety supplies a relatively discreet aromatic frame for freshness, site, and élevage. Its most distinctive expression is therefore a meeting between a restrained grape and the Loire vineyards where it became established.

History and identity

Plantgrape places Melon’s origin in Bourgogne–Franche-Comté and reports that published genetic analyses indicate a cross between Pinot and Gouais blanc.1. UMT Géno-Vigne (INRAE, IFV and L’Institut Agro Montpellier), “Melon B,” Plantgrape varietal record, accessed 7 September 2026: https://www.plantgrape.fr/fr/varietes/varietes-a-fruits/161/export.

The variety is commonly styled Melon de Bourgogne in English. Muscadet names the appellation and wine category here; in the INAO record for Muscadet Coteaux de la Loire, its wines are made from the single variety Melon B.2.

Viticulture

Melon has small to medium-sized clusters and small berries. Plantgrape places budbreak about two days after Chasselas and maturity in the second period, about two weeks after Chasselas. It describes the variety as suited to clay-siliceous soils and fairly cool areas, with moderate long pruning or, in some circumstances, short pruning. Its disease profile is uneven: it is fairly susceptible to downy mildew and very susceptible to grey rot, while being less susceptible to powdery mildew and eutypa dieback.1. UMT Géno-Vigne (INRAE, IFV and L’Institut Agro Montpellier), “Melon B,” Plantgrape varietal record, accessed 7 September 2026: https://www.plantgrape.fr/fr/varietes/varietes-a-fruits/161/export.

Those traits help explain the Loire association. Fairly cool conditions suit the variety and can preserve the freshness expected in dry Muscadet, while its sensitivity to rot makes weather and harvest conditions important. Plantgrape describes the wines as fresh, light, balanced, and discreetly aromatic.1. UMT Géno-Vigne (INRAE, IFV and L’Institut Agro Montpellier), “Melon B,” Plantgrape varietal record, accessed 7 September 2026: https://www.plantgrape.fr/fr/varietes/varietes-a-fruits/161/export.

Wine character

Melon has discreet varietal aromas. This gives production and site more room to show: harvest conditions, fermentation, lees contact, and the vineyard setting can change the wine’s texture and aromatic detail without a strong varietal perfume dominating it.

In Muscadet Coteaux de la Loire, INAO describes delicate, mainly floral aromas, occasional mineral notes, and a balance oriented toward freshness.2. Institut national de l’origine et de la qualité, “Muscadet Coteaux de la Loire sur lie,” accessed 7 September 2026: https://www.inao.gouv.fr/produit/muscadet-coteaux-de-la-loire-sur-lie-15240.

Where it is grown

Melon’s defining modern home is the Muscadet area in the southern Loire, near Nantes. INAO describes Muscadet Coteaux de la Loire as extending along the sloping banks of the Loire between Nantes and Angers, where poor, stony soils and the local climate are associated with fresh wines and delicate aromas.2. Institut national de l’origine et de la qualité, “Muscadet Coteaux de la Loire sur lie,” accessed 7 September 2026: https://www.inao.gouv.fr/produit/muscadet-coteaux-de-la-loire-sur-lie-15240. The appellation was recognised in 1936, and the wider Muscadet family includes other appellations.

In the cellar

Plantgrape says that dry-white vinification has good aptitude for conservation on lees.

For Muscadet Coteaux de la Loire, sur lie wines remain on their fine fermentation lees until bottling or their first shipment from the winemaking cellar. Under the amendment published in April 2026, bottling takes place within the appellation area or its defined nearby area, between 1 March of the year after harvest and 30 June of the second year after harvest.3. European Commission, “Muscadet Coteaux de la Loire,” C/2026/2069, description of the bottling amendment and single document section 11, “Conditionnement dans la zone géographique délimitée,” pp. 3, 8–9.

Lees ageing can give Melon's light wines more roundness and texture. The appellation document connects this effect with mannoproteins and other compounds released as yeast cells break down, while limited handling and retained carbon dioxide help protect the wine from oxidation.3.
