The red grape variety originates from Portugal. Synonyms are Baroccas, Barocca, Barroco, Boca de Mina, Tinta Barocca, Tinta das Baroccas, Tinta Gorda, Tinta Grossa and Tinta Vigaria. Despite seemingly suggestive synonyms or morphological similarities, it should not be confused with the varieties Carrega Tinto, Grossa and Marufo (all with synonym Tinta Grossa) or Touriga Franca. According to DNA analyses last carried out in 2018, it comes from a presumably natural cross between Marufo x Touriga Nacional. However, this is based on only 20 DNA markers (see under molecular genetics). By the way, Touriga Franca also originated from the same parents.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
