Wine and Juice clarification.

Originating from our unique mineral reserves, our Volclay KWK® sodium bentonite products are renowned for their purity and have built a reputation as among the most trusted ingredients in the world for purification.

KWK® Food Grade and Krystal Klear premium sodium bentonite is used extensively for the clarification of organic liquids by absorbing heat-sensitive proteins and other impurities, and are particularly useful in preventing cloudiness. KWK Food Grade and KWK® Krystal Klear are used in fining of wines, juices, ciders, and vinegars for the removal of suspended solids.
