Benefits of using UF, NF and RO Membrane Systems in Winemaking
Volatile Acidity Reduction
Correcting elevated volatile acidity is crucial for wine quality. Using RO you can selectively reduce volatile acidity while retaining the essential components that contribute to the wine’s complexity, ensuring a clean and stable product.
Selective Taint Removal
From smoke taint to Brettanomyces contamination, membrane filtration offers a targeted solution. RO and NF membranes can selectively remove unwanted taints while preserving the wines core characteristics, giving you control over even the most challenging winemaking conditions.
Enhance Aroma and Flavour Intensity
Membrane systems allow you to concentrate specific wine fractions to enhance aromatic intensity and flavour richness, creating wines that stand out in a competitive market. This enables greater customisation and differentiation for premium and boutique wines.
Precision Alcohol Adjustment
Our Reverse Osmosis (RO) systems allow for precise removal of alcohol without compromising the delicate flavour balance. This technology ensures you can create wines with ideal alcohol levels to meet market demands and regional preferences.
Minimise Product Loss
Compared to traditional correction methods, UF, NF and RO membranes enable more efficient separation with minimal wine loss, preserving more of your valuable product during the correction process.
Improved Wine Stability
Nanofiltration (NF) and Ultrafiltration (UF) membranes are highly effective for removing undesirable proteins, ensuring protein stability in your wines. This reduces the risk of haze or sediment formation, keeping your wines clear and visually appealing throughout their shelf life.
Colour and tannin Management
Ultrafiltration (UF) membranes enable the removal of unwanted colour compounds and excess tannins while preserving desirable phenolic qualities. This technology helps refine your wine’s visual appeal and mouthfeel for a more balanced and elegant product.
