The variety is a descendant of Gouais blanc and is characterized by moderate vine vigor. The leaves are large to medium, round, five-lobed, slightly dissected, and without pubescence on the underside.
The clusters are medium-sized, conical, and medium-dense. The berries are medium to large, round, white in color, and covered with a bloom of medium density. The skin is thin, and the pulp is juicy. The yield of the variety is high; however, it has low resistance to frost and fungal diseases.
A wine variety used for producing white wines with high acidity and a neutral taste, and also historically permitted for the production of Armagnac. In rare cases, it can be used for fresh consumption.
