Name for the black currant (Austrian "schwarze Ribisel"), or essence produced from it (thick syrup). According to the taxonomic system, the plant belongs to the subclass Rosidae (rose plants), as does the grapevine.

At the beginning, the vessels are shaken every few days to accelerate the extraction
