The red grape variety (also Malvarisko) originates from Portugal. According to DNA analyses carried out in 2015, it is a presumably natural cross between Alfrocheiro x Tinto Cão. However, this is based on only 21 DNA markers (see molecular genetics). The vine is grown in small quantities in the Beira Interior, Ribatejo and Trás-os-Montes areas. In 2016, three hectares of vines were designated (Kym Anderson).
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.
