The red grape variety originates 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 Amaral variety (Azal Tinto) or the other Touriga varieties, despite seemingly suggestive synonyms and morphological similarities. There is no connection with the white variety Bical. Direct descendants through presumably natural crossings are Tinta Aguiar, Tinta da Melra, Touriga Fêmea and Touriga Franca. It was also a crossing partner in the new variety Tarrango. The medium-maturing, low-yielding vine is susceptible to powdery mildew and botrytis, but resistant to heat and drought. It yields red wines that are dark in colour, high in tannin, acidity and extract, with significant, intense aromas of bergamot, cistus, rosemary and violet, as well as ageing potential.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.Dr. Edgar Müller
