Application Highlight: Filterability Testing of Wine with Software Application
Last updated: April 2021
Overview
Some wines can be problematic during the sterile filtration process. They have the potential to clog filtration membranes with particulates (microbes, crystals) or associative/macromolecular colloids. Filterability testing is used to identify these potentially problematic wines, measuring particulates and colloid particles in contrast to light-scattering techniques such as turbidity, which only measures membrane-clogging particulates.
Sartorius offers an integrated system that includes a stainless steel tank, valves, filter holder and pressure regulator, as well as a Cubis® II MCA precision balance with the Filterability Index software application. The software continuously measures filtered volume and time and according to the French method calculates the Filterability Index (IF), modified Filterability Index (IFM) and Vmax or according to the Italian method calculates the Clogging Index (CI), modified Clogging Index (MCI) and Vmax2.

Key Takeaways
- When dealing with wine filtration, problem microbes are usually yeasts (kloeckera apiculata, Zygosaccharomyces bailii, etc.) or bacteria (pediococcus, lactobacillus, etc.)
- The Filterability Index software for Cubis® II balances accurately measures wine particulates and addresses the industry's need for accurate filtration testing
- It automates the filterability testing process, reducing handling errors and saving time for winemakers and quality control labs
- The application provides robust predictions of membrane impact during sterile filtration, helping to prevent costly filtration issues
- Users are guided through the process with automatic result calculations, ensuring reliable and consistent test results
