Red Wine Clarification and Protein Adsorption

Clarification early after finished fermentation is an important step to assure wine uniformity, purity and stability and to prevent wine defects. Moreover, it considerably improves the subsequent filtration and reduces expenses. In addition, already during clarification, selected treatment agent combinations create a certain balance positively affecting sensory evaluation.

Bentonite is a multi-layer clay mineral for protein adsorption and clarification. The application range of an individual bentonite depends on the selected raw material and refining process.

In some cases, bentonite can be added before fermentation. In red wine making, protein reduction plays rather a minor role, compared to white wine.
