The red grape variety comes from southwest France. Synonyms are Courbu Rouge, Courbut, Dolcedo, Dolceolo, Grünstieliger and Noir du Pays. It must not be synonymous with the Hondarribi Beltza or Manseng Noir varieties, even if they seem to indicate synonyms or morphological similarities. It has been/is grown with both varieties in a mixed set. Courbu Noir and Manseng Noir not only share the synonym Courbu Rouge, but were formerly known together as "Noirs du Pays"; in any case, there are family relations. However, there is no connection to the white-berry variety Courbu Blanc. The late ripening, rather low-yielding vine is susceptible to powdery mildew. It produces light-coloured, rather low-tannin red wines. The almost extinct variety is registered in the southwest of France in the Béarn area, but is no longer of any significance. In 2016, only one hectare of vineyard area was designated (statistics Kym Anderson).
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
