Divergan F (PVPP)

Divergan F ® (PVPP) is used throughout the world for fining must and wine. BASF’s unique polymerization process produces the purist polyvinylpolypyrrolidone, which is completely insoluble in must and wine. Divergan F is selective in binding phenolic species such as catechins and leucoanthocyanidins with minimal effect on flavor and aroma. It is frequently used to stabilize the delicate color in White Zinfandel and to help prevent “pinking” in certain white wines, thus ensuring a proper shelf life.
