About the production Bentonite for wine clarification
BENTONITE FOR WINE CLARIFICATION
ruseng

One of the important wine quality characteristics is its clarity. Self-clarification of some wines is not good, so they have to be filtered and clarificated supplementary. Bentonite is efficiently used for wine clarification. If bentonite is included in proper quantity, flakes appear in wine and immediately during several days residue at the bottom of the cup and carry out dregs.

Bentonite produced follow the requirements of Industrial Standards 18-49-71 Bentonite for wine industry.

Quality performances are presented in Table.
