General Information

Mosc. Grano Menudo


Origin: The Muscatel grapevine family must be the oldest known to humankind that has survived to the present day. It is assumed that it came from the Orient with the Phoenicians, Greeks, and even the Romans, and thus spread across the whole of Europe (Portugal, Spain, France, Germany, etc). Officially, this variety is considered important today in the new world of wine and in France alike. Viala and Valmorel (1905) listed 180 different types of muscatel. The first reference in Iberian literature was made by Alonso de Herrera in 1513. Clemente described this variety in 1807.

Chief areas of distribution: Despite its qualitative superiority, the cultivation of this variety has declined over the last few hundred years, in contrast to the other large berry muscatels described here. In 1914, Garcia de Salomones mentioned this variety as being present in almost all regions. Today, it is grown in the North only; in the North and North-West of Spain and in the Douro region in Portugal at an altitude of between 500 and 700 metres, and in the districts of Favaios, Alijó (at higher altitudes), and Sanfins do Douro.
