Divergan® F is BASF’s standard excipient for the filtration and stabilization of beer and wine. This beverage clarifier and stabilizer is a cross-linked, insoluble polyvinylpyrrolidone, which is also known as PVPP. Compared to Divergan® RS, Divergan® F is used for single-use applications, and it is a fine particle.
For more than ten years it has been a recognized enological procedure for the treatment of wine and sparkling wine. Both BASF Divergan® products are manufactured according to a special polymerization procedure. The ensuing dense molecular structure makes PVPP insoluble in water and all standard solvents. Good stabilization results are obtained without additional plant expenditure if relatively low quantities of Divergan® F are added together with the continuous diatomaceous earth dosage. The combined use of Divergan® F with silica gel is well known. Higher cycle times in diatomaceous earth filtration are frequently observed with the use of Divergan® F.
