Verdelho (PT)

Variety: white | Category III | Portugal

General Information


Origin: Portuguese archipelagos in the Atlantic. It is possible that this variety was brought to Madeira by Dom Afonso V in the 15th century, together with the Malvasia and other Greek varieties, from the Mediterranean island of Candia in Crete.

Chief areas of distribution: This variety is hardly grown on the Portuguese mainland. It is found in very limited areas of the Azores, Madeira, and probably the Canary islands, but has been widely distrubuted in the new world of wine. Australia has 1,603 ha, whilst oenologists recommend it in South Africa and Argentina. In Régua's ampelographic collection, Truel (1984) refers to the Verdelho on the Douro River, using the synonym Gouveio, astonishingly, with photographs typical of the variety, and an aberrant description of the Verdelho from the Dão region. This misunderstanding merely serves to highlight the extent of the enigma surrounding this magnificent and internationally-renowned Portuguese variety. A significant upswing in the cultivation of the Verdelho on the Portuguese mainland is expected in the near future, since it has now been authorised in those areas where its historic synonyms were first planted.

Official synonym(s) (national and OIV): None.

Historic and regional synonyms: Unknown.

Homonym(s): Other varieties are the Verdelho Roxo (Nº 331), Verdelho-Tinto (Nº 332), Verdello (ES), Verdejo (ES), and Verdello (IT). The historical Verdelho of the Portuguese mainland Verdelhos was the Gouveio (Nº 142) (cf. Ruy Fernandes, 1531; Lacerda Lobo, 1790; Teixeira Gyrão, 1822; Vila Maior, 1875), but this homonymity was clarified in 2000.

Area under cultivation: Hardly any cultivation on the mainland. On the islands, 20 ha are planted to this variety.

New plantings: Almost no plantings on the mainland, because virus-free propagating material does not yet exist.

Trend: Probably upward in future.

Varietal variability: Not yet researched.

Availability of propagating material: Hardly available at all.
