Bentonite is a negative charged, clay-like mineral, that, like sparkaloid, removes positively charged particles. The bentonite is a clay created by weathered volcanic ash. The material is very absorbent and it binds and bonds onto any floating particulates which cause haziness or cloudiness in wine. Once it binds to these particles, it will eventually fall out of the wine helping improve its overall clarity.
