Small Lots - Sterile Filtration

Hello Friends,
I have quite a few small lots (Kegs and Carboys) of wine in 2019 that I need to manually bottle. I am seeking guidance for sterile filtration options. Please let me know.

Thank you,
Vamsi

Vamsi - For small lots I use a 10inch Pall Advanta cartridge system that I bought on Ebay for a song. For what you’re asking it depends on the wine, it’s pH, clarity, and what you’re trying to achieve. That will determine how you select a depth pre-filter before moving down to a lower exclusion size for yeast or bacteria if you need to. I buy cartridges direct from a manufacturer in NH … https://www.criticalprocess.com/. Their website has a lot of good information in it. Just look around in the Food and Beverage Industry pages. I’ve used both their pleated fiberglass depth filters at 1micron and their PES filters down to 0.45 microns.
