- Clarification and stabilization
- Bottling prefiltration
- Final membrane filtration
- Hygienic bottling

Tartrate/protein stabilization and final microbial filtration serve different roles. Filterability testing informs downstream loading.
The pictured ROKI TECHNO adsorption cartridges are reviewed for clarification/pretreatment. Their role is separate from downstream final membrane filtration; verify microbial-retention performance, filter grade and integrity-test conditions using evidence for that membrane.

Connection principles and operating/test methods
Staged filtration before bottling
Fluid
Scroll horizontally to see the complete flow.
Review tartrate and protein stabilization separately. Test filterability and color and aroma losses before defining the stages.
These conceptual views explain flow direction. Actual piping, wiring and physical flow rates require a separate design.
01 — PROCESS
Where does each step fit?
Define the intended use and conditions to identify the required role of each item.
Stabilization and filterability testing
Measure colloidal load and filterability before bottling, then select pretreatment.
Final membrane and bottling
Check retention performance for target microorganisms, as well as the bottler, bottles, closures, and supply gases.
02 — SELECTION
What should be selected and verified?
Wine clarification, microbial stabilization, and tartrate and protein stabilization are separate control tasks. Review upstream treatment and storage conditions together, rather than simply adding a final filter immediately before bottling.
Scroll horizontally to review all columns.
| Process objective | Step to review | Selection evidence |
|---|---|---|
| Lees and sediment | Depth filtration / pretreatment | Solids load and loss of color and aroma through adsorption |
| Final membrane protection | Filterability testing | Fouling rate in addition to turbidity; throughput before and after pretreatment |
| Spoilage and refermentation control | Final membrane | Residual sugar, organism types, alcohol and pH, and microbial retention validation |
| Appearance stability | Evaluate separate stabilization processes | Tartrate and protein stability tests; storage temperature |
These examples start the application review. Pore size or nominal rating alone does not establish suitability or retention; confirm with the actual process fluid and supplier evidence.
03 — OPERATING CHECKS
Use operating data to identify improvements.
Testing is needed even when wine looks clear
Low turbidity alone is a poor predictor of bottling filter life. Compare filterability at constant pressure using representative feed wine.
Check changes in color and aroma
Review membrane material and adsorption characteristics, the initial flush, and differences in sensory properties and color before and after treatment.
Investigate downstream contamination as well
Even if the filtrate meets requirements, recontamination can occur through bottling equipment, gas, or rinse water. Sample at separate locations to identify the cause.
04 — QUESTIONS
Frequently asked questions
Does the final filter also solve tartrate problems?
Capturing particles that have already formed is different from stabilization to prevent future crystal formation. Verify tartrate stability using separate processes and tests.
Is checking the 0.45 µm label enough?
Check the membrane's actual retention data for target microorganisms, operating conditions, and integrity criteria. Product-specific suitability tests are also needed.
