The variety possesses high growth vigor and productivity. The berries are distinguished by a thick skin and a high level of natural acidity. The variety requires yield control to maintain the quality of the raw material.
It is used exclusively for technical purposes for wine production. In single-varietal wines, it exhibits a neutral and coarse character, therefore it is more often used in blends, where it is valued for its ability to impart freshness and structure.
