Wine Filtration

Updated: Oct 20

Each wine has a unique character that must be preserved, where taste and intensity of flavour has to be balanced delicately due to the complexity of the chemical structures in wine. Contaminants such as crystals, treatment residues, organic aggregates, bacteria and yeast can significantly impact a wine's quality. It's removal is essential to maintain the distinct flavour and colour of wine and spirits.

While filtration is needed to remove contaminants that can cause spoilage, the filtration process should not alter the flavor and colour characteristics that make that wine special.

  • Clarifying filters to produce a clear, aesthetically pleasing final product

  • CO2 filtration for sparkling wines

  • Bottle washing and utility water filtration
