Bentonite

A type of light clay, mixed into wine to clarify it by removing tiny suspended protein molecules that can cause a hazy appearance (see FINING). As the bentonite settles, it absorbs and carries the particles suspended in the wine along with it to the bottom of the vessel. The clear wine is then racked off the settled material.
