Australia’s wine industry—spanning Barossa’s bold reds, Yarra Valley’s elegant pinots, and Tasmania’s premium sparklings—relies on advanced wine filtration solutions to ensure clarity, microbial stability, and sensory preservation.
CoPure partners with Cobetter, a globally trusted name in filtration technology, to supply Australian wineries with depth and membrane-based filtration systems designed to deliver clarity, stability, and efficiency across a range of wine styles. Whether you’re perfecting the brilliance of a fresh white or maintaining the finesse of a reserve red, CoPure’s wine filtration expertise helps producers safeguard quality with confidence.
Why Wine Filtration Matters in Australia
Australian wineries face diverse climate, grape, and microbial conditions—making filtration a vital step in the winemaking process. Key benefits include:
Microbial Safety & Stability
Final membrane filtration (e.g., 0.45 µm PES or nylon) is critical for removing spoilage organisms and residual yeast, helping avoid bottle refermentation and off-flavours, especially in bottled and exported wines.
Improved Clarity & Shelf Appeal
Filtration reduces haze-forming particles and yeast residues, producing crystal-clear wines that meet consumer expectations—especially in white, rosé, and sparkling styles.
Shelf-Life Extension
Effective microbial removal and reduced oxidative potential lead to more stable wines, ready for longer shelf lives in both domestic and international markets.
Operational Consistency
Membrane and depth filtration systems offer reproducible results across batches and vintages, giving winemakers greater control over quality and efficiency.
Regulatory Compliance
Clean, stable wines are easier to certify and export. Validated filtration helps meet FSANZ and global market standards for bottled wine stability and clarity.
CoPure & Cobetter Wine Filtration Solutions
CoPure supplies a comprehensive lineup of Cobetter’s depth and membrane filtration products tailored to the wine industry’s unique needs:
Depth Filtration (Pre-filtration Stage)
Cobetter’s depth filters—constructed from cellulose or diatomaceous earth—are used to remove larger particulates like grape solids, residual yeast, and tartrate crystals. They reduce the load on final membrane filters and extend system life.
Membrane Filtration (Final Polish)
Membrane filters using polyethersulfone (PES) or nylon with pore sizes between 0.8 µm and 0.45 µm are used for polishing and microbiological stabilization. These filters remove Brettanomyces, lactic acid bacteria, and unwanted yeasts without affecting wine flavour, aroma, or structure.
Vent Filters & Gas Filtration
Cobetter also offers hydrophobic PTFE gas filters for tank venting and sterile gas exchange. These are critical during bottling to avoid oxygen ingress or contamination via CO₂ or nitrogen.
Validation & Integrity Testing
CoPure supports wineries with Cobetter’s validated test protocols including pressure hold, microbial challenge testing, and integrity certifications—ensuring that filtration meets technical, safety, and export requirements.
Industry Insights: What the Research Says
Minimal Sensory Impact from Membrane Filtration
AWRI studies confirm that modern membrane filters (e.g., 0.45 µm PES) have minimal impact on phenolics, colour, and mouthfeel. After 18 months of bottle aging, sensory evaluations showed no negative effect on wine character.
Improved Colour and Aroma
In blind tastings, wines filtered with modern membrane technology were often described as cleaner on the nose and more vibrant in appearance. Particularly in whites and rosés, membrane filtration enhanced aromatic clarity.
Debunking the Over-Filtration Myth
Concerns about “filter shock” typically stem from coarse pads or aggressive filtration setups, often in small-scale or home winemaking. When applied correctly, membrane filtration at commercial scale preserves the wine’s structural and aromatic integrity.
Benefits of Wine Filtration with CoPure Systems
Here’s how wineries benefit from implementing CoPure’s depth and membrane filtration systems:
Reduced wine loss
Proper filter sizing and flow rate control ensure maximum recovery, especially in membrane-based systems.
Labour and consumable savings
Efficient filtration systems reduce the number of passes required and limit filter changeouts during production.
Environmental benefits
Cobetter’s membranes are compatible with clean-in-place (CIP) protocols, reducing water, chemical, and energy usage.
Consistent clarity and turbidity control
Wineries report final turbidity levels consistently below 1 NTU, with dissolved oxygen levels well within bottling specs.
Data traceability
Filter performance and integrity validation can be documented for internal quality control or third-party audits.

Designing Your Ideal Filtration Strategy
Whether you’re a boutique operation or a mid-sized producer, filtration planning starts with a few key steps:
Define wine style and output volume
Whites, rosés, and sparkling often benefit from membrane filtration.
Reds may require depth filtration for controlling tartrate and yeast.
Select the correct filter sequence
Pre-filtration: Cellulose or DE depth filters (1.0–0.8 µm)
Final polishing: 0.45 µm PES or nylon membrane
Gas filtration: PTFE membrane vent filters for CO₂/N₂ sterilisation
Determine validation and cleaning protocol
Use pressure-hold or bubble point tests for membrane integrity
Design a CIP cycle for longevity and hygiene
Track performance KPIs
Monitor turbidity (NTU), DO levels, volume recovery, and filter throughput
Log membrane performance across bottling runs to evaluate cost per litre filtered
Wine filtration is not just a technical step—it’s an essential quality control measure that shapes how your wine is experienced in the glass. With CoPure, Australian wineries can access globally proven membrane and depth filtration systems engineered to support:
Clarity
Stability
Sensory preservation
Operational efficiency
