PVPP is a gentle fining agent which preserves wine aroma, unlike some other fining agents. When used for colour reduction in white wines, combining with carbon is more effective in many cases, as it helps with clarification of the carbon particles.

Polyclar, the brand name for PVPP plastic particulate, is a unique fining agent that absorbs phenolic compounds and unwanted tannins as well and deactivates oxidative enzymes within the wine. It is especially useful for removing oxidative odors and preventing browning in whites and reds, especially when used in conjunction with activated charcoal.

PVPP, short for polyvinylpolypyrolidone, is a synthetic polymer that is effective in absorbing and precipitating polyphenols, responsible for browning in wines as well as excessive bitterness in red wines. PVPP is typically used as a preventive fining agent to avoid such problems.

2023年6月30日 · Much fuss is being made in the wine industry about sustainability and going green. For this reason, some parties are starting to make a big stink about PVPP use in cellars, as it ultimately adds to our plastic polluted planet problem.

PVPP Divergan F® 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.

PVPP is a resinous polymer that acts similarly to proteinaceous fining agents. It is particularly useful in the selective removal of flavans and mono- and dimeric phenolics. As such, PVPP has particular value in diminishing undesirable bitterness in white wines. It is usually added relatively early in maturation.

2024年12月1日 · Polyvinylpolypyrrolidone (PVPP) is commonly employed for fining in fruit wine brewing. This study aimed to investigate the impact of PVPP pretreatment on the formation of fermentation aroma and polyphenol distribution in Rosa roxburghii Tratt (RRT) wine.

Polyclar V is a highly effective 100% PVPP wine stabilizer with an average particle size of around 25 microns. It is optimized for maximum, fast-acting reduction of polyphenols, such

In winemaking, PVPP is used for fining and stabilising. It is used to bind and remove phenolic substances (tanning and colouring agents) and their oxidation products. It has a much more specific effect than protein-containing agents such as gelatine or casein.
