Mauzac noir is a red French wine grape variety that is grown in Southwest France.
Today Mauzac noir is nearly extinct but at least one grower in the Gaillac AOC is attempting to revive the variety and make varietal examples of the grape.
[1] The earliest recorded mention of a Mauzac grape dates a 1525 document titled Livre de raison written by Antoine Antiquamareta who was the seigneur (or lord) of Villeneuve-lès-Lavaur in what is now the Tarn department.
Master of Wine Jancis Robinson notes that another commune, Meauzac, in the Tarn-et-Garonne may have a connection to the two grape varieties.
[1] Mauzac noir is a mid-ripening grape variety that, what it can be very vigorous and produce expansive foliage, tends not to be very high yielding.
