The red grape variety originates from Portugal. Synonyms are Arruya, Casculo, Moreto (see there), Moreto d'Alenteijo, Moreto d'Alentejo, Morito, Mureto, Mureto do Alentejo and Tinta de Alter. According to DNA analyses carried out in 2013, it is a presumably natural cross between Jaén Blanco (Cayetana Blanca) x Alfrocheiro. However, this is based on only 20 DNA markers (see Molecular Genetics). Despite seemingly suggestive synonyms or morphological similarities, it must not be confused with the varieties Baga, Blauer Portugieser and Moreto do Dão. The late-ripening vine is resistant to fungal diseases. It produces red wines with a weak colour and low acidity and discreet red fruit aromas, which are mainly used for blends. The variety is widespread in the Portuguese areas of Alentejo, Algarve, Bairrada and Ribatejo. However, no stocks were reported in 2016 (Kym Anderson statistics).
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.
