Wine Filtration Solutions
Global Filter filtration solutions are designed to control wine clarity and microbiological stability while preserving its organoleptic characteristics.
Filtration, a key step in wine production
Filtration is a key step in wine production. It helps achieve a clear and bright wine while contributing to its stability and proper evolution after bottling, without stripping the wine or altering its organoleptic characteristics.
Global Filter develops filtration solutions adapted to the different stages of the winemaking process, while respecting the wine’s aromatic expression. We design and manufacture filter housings and consumables (cartridges, filter sheets, filter bags, etc.) dedicated to the wine industry. Our French manufacturing site is located in Orange, near Châteauneuf-du-Pape, at the heart of a renowned wine-producing region.
Our expertise also enables us to optimise your filtration processes. The quality and traceability of our products ensure consistent and repeatable performance.
The essential role of filtration in wine quality
Clarity and brightness
Reduce fine lees, suspended particles and substances responsible for turbidity to achieve the desired clarity and brightness before packaging.
Microbiological stability
Control spoilage yeasts and bacteria that could lead to refermentation, off-flavours or undesirable changes in the wine after bottling.
Wine preservation
Adapt the filtration level to remove unwanted contaminants while limiting the impact on the wine’s colour, aromas, flavours and structure.
Filtration performance
Control fouling, pressure drop and filter service life through prefiltration adapted to the wine’s turbidity and filterability.
Where does filtration take place in the winemaking process?
Utilities
Process and rinse water
Prefiltration and final filtration of water used throughout the process.
Air / gases (nitrogen, CO₂)
Filtration of air and gases used in the process to control their quality and protect sensitive production stages.
Tank vents
Hydrophobic GGPTFE or PSH membranes used during fermentation and bottling to limit the ingress of contaminants.
The wine production process in detail
From clarification to bottling, each stage requires a filtration level adapted to the wine quality and the filtration objective.
From clarification to wine bottling: which filtration should you choose?
Coarse clarification
Coarse clarification reduces larger particles, lees and suspended solids present after the initial stages of winemaking.
Global Filter solutions:
FG / PP pleated cartridges, filter sheets or lenticular modules.
Clarification
This stage reduces fine particles and colloids responsible for turbidity, improving wine clarity and brightness while preparing the product for finer filtration stages.
Global Filter solutions:
FG / PP pleated cartridges, filter sheets or lenticular modules.
Prefiltration
Before final filtration, appropriate prefiltration reduces the residual particulate and microbiological load. It helps protect the final membrane, limit premature fouling and extend its service life.
Global Filter solutions:
GGPES membranes, FG / PP pleated cartridges, filter sheets or lenticular modules.
Final wine filtration
Before bottling, final filtration retains spoilage yeasts and bacteria that could affect wine stability. Polyethersulfone (PES) membranes provide defined microbiological retention while preserving the wine’s organoleptic characteristics.
Global Filter solution:
GBPES Series PES membranes.
Wash and rinse water
Filtration of water used for washing and rinsing helps control its particulate and microbiological quality and limit the risk of cross-contamination throughout the process.
Global Filter solutions:
Prefiltration: GWTB, GCTB, GATB or PP Series
Final filtration: GFPES Series – PES membrane
Wine filterability: a key parameter
Not all wines behave in the same way during filtration. Turbidity, the presence of colloids and the nature of suspended solids can directly affect filter fouling and service life. Assessing wine filterability helps define an appropriate filtration strategy and correctly size the filtration equipment.
Turbidity (NTU)
Turbidity measures the presence of suspended matter in the wine. It is an indicator of wine clarity and helps guide the selection of clarification and prefiltration stages.
Fouling Index
The Fouling Index assesses the wine’s tendency to foul the filter media and helps determine an appropriate prefiltration strategy.
Vmax
Vmax estimates the maximum volume that can be filtered before reaching a critical pressure drop. It helps determine the required filtration area and estimate cartridge service life.
Our different filtration technologies for wine
Depth filtration
For wine clarification and reduction of the particulate load before finer filtration stages.
Lenticular filtration
Depth filtration in a closed system suitable for different stages, from clarification to fine filtration depending on the selected grade.
Filter sheets
Depth filter sheets are suitable for clarification and for reducing particles and substances responsible for wine turbidity.
Pleated cartridges
A range of filter media and retention ratings adapted to the different stages of wine clarification, prefiltration and polishing.
PES membranes
For final filtration and microbiological control before bottling, with the possibility of performing membrane integrity testing.
