Phenolic Adjustments and Protein Stability

Phenolic Adjustments and Protein Stability


Phenolic compounds and proteins play an adverse role in wine quality, resulting in undesirable compounds in your wine. Our advanced phenolic adjustment membranes can specifically extract these undesirable components, significantly improving the quality and colour of the wine.

How does it work?

The Memstar range of machines provides comprehensive adjustment capabilities. Filtering the wine through advanced membranes tuned to phenolic compounds, the process dramatically improves the protein stability, colour and quality of hard pressings. A very valuable co-factor is created that can be added to red wine to improve texture and colour stability. The filtrate can then be blended back into the free-run which improves the quality and margin for the winery.
