ŒNOLOGICAL APPLICATIONS
Insoluble polyvinylpolypyrrolidone is a reticulated N-vinyl-2-pyrrolidone polymer known more commonly as PVPP. Added to must or wine, PVPP eliminates certain phenol substances responsible for browning or organoleptic deviations in certain wines.
PVPP is insoluble. It fixes the substances responsible for the browning of wines and also fixes certain molecules that add bitterness to the taste of the must or wine.
- PVPP is recommended :
• As a preventive : for white wines that may be stored in difficult conditions or for a long time.
• As a curative : for wines that are oxidised or taste bitter. - ‘
