The red grape variety originates from Portugal. Synonyms are Baroccas, Barroca, Barrocas, Barroco, Boca de Mina, Tinta Barocca, Tinta da Baroccas, Tinta das Baroccas, Tinta Gorda, Tinta Grossa and Tinta Vigaria.
According to DNA analyses carried out in 2018, it originates from a presumably natural cross between Marufo x Touriga Nacional. However, this is based on only 20 DNA markers (see molecular genetics). It should not be confused with the Carrega Tinto, Grossa and Marufo varieties (all with the synonym Tinta Grossa) or Touriga Franca (same parentage) due to some of the same synonyms or morphological similarities.

If I were to rate websites, you would deserve the highest rating. It is rare to come across websites that provide such a large amount of data and are still so intuitive to use. Respect for the lovingly researched and informatively prepared encyclopedia. Keep it up!
