The red grape variety comes from Portugal. Synonyms are Azal Espanhol, Bical, Bical Tinto, Mortagua, Mortagua Preto, Touriga, Touriga Fina, Tourigo, Tourigo Antiguo, Tourigo do Dão (Portugal); Touriga National (Romania); Carabuñera (Spain). It must not be confused with the variety Amaral (Azal Tinto) or the other Touriga varieties, despite the fact that synonyms and morphological similarities appear to indicate this. There is no connection with the white variety Bical. According to DNA analyses carried out in 2011 and 2013, it is a parent variety of Touriga Fêmea and Touriga Franca. It was also a crossbreeding partner in the new breeding of Tarrango. This medium-ripening, low-yielding vine is susceptible to powdery mildew and botrytis, but resistant to heat and drought. It produces colour-dark, tannin-, acid- and extract-rich red wines with significant, intense aromas of bergamot, rockrose, rosemary and violet, as well as storage potential.
