🍷 PVPP

PVPP is a synthetic plastic powder used to remove bitter compounds and brown colour from wine. PVPP, or polyvinylpolypyrrolidone, is a synthetic powder used in winemaking for fining. It removes bitter substances and substances that cause browning from wine, mainly phenolic compounds. This helps white and rosé wines keep a pale colour and soft taste.

The powder is added to the wine, binds the unwanted substances, then settles together with them and is removed by filtration. None should remain in the finished wine. The use of PVPP is permitted by winemaking rules and limited by set norms.

PVPP is one of the fining methods, that is, ways of clarifying and cleaning wine. Among fining agents it stands out because it contains no animal products. Unlike gelatin or egg white, PVPP is suitable for vegan wine. That is why it is often chosen by those who make wine without animal additives. Whether to use it is up to the winemaker, depending on the style of the wine.
