Bentonite is a natural clay that is widely used in winemaking to clarify and stabilize wine. It is a negatively charged colloid that attracts and binds to positively charged proteins and other haze-forming particles in wine. This causes the particles to settle out of the wine, leaving it clear and bright.


Bentonite can be used at any stage of the winemaking process, but it is most commonly used after fermentation. It can be added to the wine must, juice, or finished wine. The dosage of bentonite will vary depending on the type of wine being made, the desired clarity, and the amount of haze-forming particles in the wine.
