The red grape variety comes from Portugal; the profane name simply means "berry". Synonyms are Baga de Louro, Bairrada, Bairrado Tinta, Baya, Carrasquenho, Carrega Burros, Goncalveira, Morete, Moreto, Paga Divida, Poeirinha, Poeirinho, Povolide, Pretinho, Tinta Bairrada, Tinta Bairradina, Tinta da Bairrada, Tinta de Baga, Tinta Fina and Tinto de Bairrado. It must not be confused with the Camarate (Moreto), Moreto do Alentejo or Pedral varieties, even though synonyms or morphological similarities are indicated. This late-ripening, high-yielding vine is susceptible to botrytis but resistant to powdery mildew. The wines can vary extremely from draught wine to top quality. That is why the spirits of this variety are divided.
Baga is mainly grown in the DOC area Bairrada near the Atlantic coast and in the DOC area Dão to the east, where there can be a lot of rain in autumn. Therefore it is often difficult to reach full ripeness of the grapes. In the best case, red wines rich in body, alcohol and tannins result with a variety of aromas of black plums, herbs, olives, blackcurrants and tobacco. However, there can just as well be light-coloured, thin wines that are best suited for the production of rosé or sparkling wines. In the famous rosé wine Mateus, by the way, it is one of the most important varieties. In addition to the areas mentioned above, it is also cultivated further north in the Douro port wine area and in the Beiras region. The Portuguese cultivated area in 2010 was 4,108 hectares. This puts it in 123rd place in the worldwide grape variety ranking.
