Chitosan is a natural polymer derived from the shells of crustaceans. It is a powerful clarifying and fining agent that is commonly used in winemaking to remove suspended solids, such as yeast cells, bacteria, and proteins. Chitosan can also be used to reduce haze and improve color stability in wine.


Chitosan works by binding to suspended solids and forming flocs that settle to the bottom of the wine. The flocs can then be removed by filtration, leaving the wine clear and bright.


Chitosan is a safe and effective fining agent that is approved for use in organic winemaking. It is also a good choice for winemakers who are looking to avoid using animal-derived products.
