The variety has medium vine vigor and medium fertility (about 1.2). Berries and clusters range from small to medium size. Sugar content in the berries is usually about 19° Brix with a balanced sugar-to-acid ratio of about 30:1.
For cultivation, an open-gable trellis system with an angle of inclined arms greater than 120° is recommended to improve aeration and light exposure. Semi-long pruning to 6–8 buds is applied, and in cold regions, pruning to fruit canes. The variety requires careful canopy management, including leaf thinning and removal of excess shoots.
