What does the bentonite that comes with my wine kit do?
A-Bentonite provides particulate matter to which the yeast clings and so it aids the fermentation process. It also is a clearing agent and attaches itself to particles in the wine and settles them out at the bottom of the fermenter. In wine making, bentonite removes proteins and other haze producing particles. The addition of bentonite at the beginning of fermentation is known as counterfining.
