The variety forms medium-vigor vines with semi-erect shoot growth and early bud break. The leaves may have a corrugated structure, resembling the Madeleine royale variety.
Clusters are medium-sized, conical, and often compact. Berries are medium-sized, spherical or slightly flattened in shape, with thin skin of a white or yellow-green color. The pulp is juicy, pulpy, with a simple taste.
The variety ripens approximately ten days earlier than the Chasselas blanc variety, usually by mid-July. The plant is characterized by low susceptibility to grey mold. For cultivation, it is recommended to use vigorous rootstocks, short pruning, and protected sites with southern exposure.
