Wine fining and clarification are vital steps of the winemaking process both before alcoholic fermentation and post-alcoholic fermentation, whether using static decantation or flotation (a wine clarification process where gas is directly injected into the product).
Thanks to the technologies employed in our group laboratories to monitor the clearing process in fining wine, Perdomini-IOC is able to offer a wide range of effective wine fining agents, stabilizers and clarifiers, in response to the many needs presented by wineries.
It’s important to choose the right clarifier and fining agent, and this depends on each winemaking goal. The innovative Perdomini-IOC range of wine fining agents offers:
– Inorganic wine fining agents to remove proteins and tannins, such as bentonite clays
– Organic wine fining agents for wine collage, such as gelatin and egg albumin
– Wine fining agents for oxidation, such as PVPP, silica gel and potassium caseinate
– Vegan-friendly wine fining agents, such as chitosan and plant-based proteins
The main goals of the wine fining process are many: to optimize protein stability, to remove oxidizable polyphenols and enzymes, to enable lees sedimentation, to correct the colour and the sensory profile, to enhance the limpidity and filterability of the wine.
This is why Perdomini-IOC’s consultancy service helps wineries choosing the most effective wine fining and clarifying agent, putting our 70 years’ experience in professional oenology at service. Browse our range of clarifiers and fining agents for wine.

How to clear wine from being cloudy: the benefits of wine fining agents
Wine fining agents are highly specialized products designed for treating wine at the pre or post-fermentation processes. When carried out after the grapes have been crushed, wine clarification leads to fresher and fruitier sensory profiles in white, red and rosé wines.
Fining wine leads to many advantages in wine production, including:
– Removing the components causing oxidation and browning in wines;
– Reducing turbidity and sensory defects in odours, flavours and colour;
– Early colloidal stabilization in order to preserve the limpidity of the wine;
– Improving filterability and preventing sediments in the bottle.
The wine fining process depends on many molecular properties: each stabilizer and clarifier has its own chemical properties, electrical charge and molecular weight, and its efficiency differs from the many interactions of the components to be removed from the wine.
Our range of traditional wine fining agents includes animal-based wine fining agents such as gelatin and egg albumin to remove tannins and polyphenols from wine, as well as mineral-based, vegan wine clarifiers such as bentonite to eliminate excess proteins.
Perdomini-IOC guides its customers through the many options for wine clarification and fining, in order to ensure the best wine fining agents to achieve any winemaking goal.
