Bastardo (PT)

Variety: red | Category III | Portugal

General Information


Origin: The variety was mentioned by Vincencio Alarte in 1711. In 1790, Rebelo da Fonseca described it as unmistakable because of its capacity for sweetness. In 1875, Vila Maior commented that it was known throughout the country for its early veraison. Count Odart (1874) noted the variety and deemed it to be a variant of the Trousseau du Jura (FR).

Chief areas of distribution: Douro. Australia (Gros Cabernet, 250 ha), South Africa (a Port wine substitute, 188 ha), California (Chauché noir), France (Troussau, 150 ha) and Argentinia (Pinot Gris de Rio Negro).

Official synonym(s) (national and OIV): Trousseau (FR), Merenzano (ES), Gros Cabernet (AU).

Historic and regional synonyms: Bastardinho (Dão, Algarve, Arruda), Abrunhal (Beira Alta), Graciosa (previously Nº 147).

Homonym(s): Throughout its history, there have been several varieties bearing similar names (cf. the Marquês de Carvalho, 1912, and the description of five different cultivars by J. C. Vasconcelos, 1941/2). The drafting of the official Portuguese grapevine variety list and the revision of variety names of 2000 have resulted in there being fewer Bastardos: the Bastardo Branco (Nº 36), the Bastardo Roxo (Nº 37), and the Bastardo Tinto (Nº 38) still exist.

Area under cultivation: 1,100 ha.

New plantings: 0.3%.

Trend: Growing, but at a very low rate.

Varietal variability: Not yet analysed.

Availability of propagating material: Certified clone Nº 48 JBP.

Colour intensity of wine: Very weak (1.86).

Wine colour tonality: Very weak (1.86).

Risk of oxidation of wine: High.

Ageing Potential: Good. When used in Port wine, this variety contributed the brownish colouration of Tawny port.

Wine Descriptors: This variety has a characteristic aroma. When young, it is reminiscent of wild berries and fruits, but develops to achieve complex aromas with smoky notes, coffee, dried herbs, prunes, and tobacco. With ageing, the aromas become simulaneously more diverse and deeper. After 10 years, even wines not aged in wood acquire a woody tone

Wine quality: An important ingredient in several important wines.

Variety Characteristics: Very early ripening variety with a high alcohol content, but very susceptible to rot and drying out after veraison.
