Variety description
10 August 2026
The variety is a vigorous bush with hermaphroditic flowers. The leaf is moderately dissected, three-lobed, with slight pubescence on the underside. The bunch is large, branched, and of medium density. The berry is white, rounded, medium to large in size, with thin skin and fleshy-juicy pulp.
The variety belongs to the late-maturing group. It is characterized by low maintenance requirements and high resistance to drought, with low resistance to fungal diseases. In modern ampelography, there are ongoing discussions regarding the genetic identity of Lairen and Airen, as different varieties may be concealed under similar names in various regions.
