Wine Filtration

 

Wine Quality is Everything

 

 

Enhancing Quality and Consistency in Winemaking

 

In winemaking, preserving the integrity of a wine’s flavor, aroma, and clarity is essential. That’s why choosing the right wine filtration system is critical. From removing unwanted particles to ensuring microbiological stability, advanced wine filters play a key role in delivering a clean, shelf-stable, and high-quality product.

 

Why Wine Filtration Systems Matter

 

Contaminants such as tartrate crystals, treatment residues, organic aggregates, bacteria, and yeast can all compromise wine quality. Effective filtration of wine eliminates these risks while maintaining the wine’s unique character and sensory profile.

Pall Corporation: A Global Leader in Wine Filtration

 

With over a century of innovation, Pall has become a trusted name in wine filtration systems. Our technologies are used by wineries of all sizes—from boutique producers to global brands—across every major wine-producing region. Our solutions are often seen as benchmarks for wine and lees filtration.

 

Our Legacy in Wine Filtration:

 

Pall's Solutions for the Wine Filtration Process

 

Our solutions and expertise in the wine-making process are demonstrated below with traditional and modern wine filtering system solutions that preserve quality and maintain the lowest operating costs.

  

Expert guidance through every stage of wine filtration

 

  • Wine Clarification

  • Lees Filtration

  • Colloid Removal

  • Protein Stabilization

  • Wine Bottling

  • Activated Carbon

Why is Clarifying Wine Important?

 

Clarification is the primary filtration step in the winemaking process. Yeasts and other particles from fermentation and fining are removed to reduce turbidity and improve downstream filterability.

 

The Oenoflow PRO XL System was built to help wineries achieve clarification and protein stabilization. Other benefits include:

 

  • Reduced energy usage to support goals for net zero carbon emissions
  • Reduced water usage given considerable water shortages experienced in many regions

Recover Higher Value Wine From Lees

 

Lees, the sediment at the bottom of juice, fermentation or fining vessels, can represent up to 10% of a winery’s total volume. Recovery of wine and juice from lees represents one of the most challenging forms of filtration faced by wineries.

 

Recovery of wine and juice from lees represents one of the most challenging forms of filtration faced by wineries. The Oenoflow HS system is a new crossflow filtration system designed specifically for lees processing.

After primary clarification, stabilization and maturation, fining agents, crystals, colloids and bacteria may still be present in the wine. Polishing filtration is designed to remove these particles and haze to produce a brighter wine and improve filterability for downstream processing.

 

Depth Filtration Technologies

 

Depth filtration represents a wide range of different filter sheet media which can be used for:​

 

  • Turbidity removal, from coarse to fine particles ​
  • Polishing filtration ​
  • Colloidal removal​
  • Chill haze removal​
  • Removal of microbial spoilage/ Reduction of microorganism (yeast, bacteria, mold)​

Protein stabilization and clarification are two critical steps to satisfying consumer expectations for a bright wine. While both steps prevent haze formation, one to remove heat sensitive proteins, the other suspended solids, the traditional commercial processes are typically carried out in consecutive phases adding labor, time and waste to the winemaking process. With Pall's new Oenoflow PRO XL System with Oenofine Functionality Installed, wineries can now combine these operations into a single cost saving process step.

Removing Contaminants when bottling wine is key to ensuring consistent product quality

 

Cartridge filtration is vital for removing particulates and microorganisms before bottling, preventing re-fermentation and off-flavors. A well-structured bottling program with pre filtration and final filtration safeguards brand integrity and consistent quality.

 

Supor® Beverage filter cartridges, available in 0.45- and 0.65-micron grades, are hydrophilic membrane filters that effectively retain spoilage microorganisms. Designed for durability through repeated hot water and steam sanitization, they feature an optimized pleat design and robust materials for enhanced resilience and longer service life.

Crafting a wine's inimitable bouquet while maintaining optimal intensity of flavor along with a beautiful color is the goal of every winemaker. However, in some cases, wine may have an off-taste flavor or color as contaminants can jeopardize the winemaker’s efforts. Activated carbon filtration using carbon-impregnated sheets or sheet-based modules, or carbon beds, fixes color and flavor issues. Pall offers adsorptive filtration technology which achieves color, flavor and/or odor correction. These filters have an extremely high adsorptive capacity in the filter sheet matrix and for small batches and batch corrections, carbon impregnated sheets and modules offer a simple and easy way to treat wine.
