A month ago I filtered and sweetened my plum wine. The wine had cleared since September , anyway I used this filter. Any chance it actually removed any stray yeast? There isn’t any fermentation yet.
Pleated water filter for removing yeast

It's rated 0.35um absolute which should get rid of all yeast (and other microorganisms as well!) The challenge for home winemaking is sterilizing all the remaining parts of your filtering and storage (not to mention bottling) apparatus. At the winery where I work, everything downstream of the final sterile filter is steamed (including a steam hose connecting the filter to the destination tank), and all connections sprayed with 70% ethanol as they are made. We can do a pretty good job on the home winemaking scale by thoroughly sanitizing with, eg peroxycarb, but it won't remove all risk.
I'm also concerned that it's been a month since you filtered... I would ideally want to do my final pass filtration within a few days of bottling.

I do sanitize everything, I guess time will tell. Ethanol is a good idea. Thanks for the feedback

I’ve never seen a filter .35 absolute that cheap!

When I brewed beer I used filters all the time, what is did once used is back flowed the filter with higher pressure to force off a lot of the thing that it caught and then put it in a ziplock and put in the freezer. that way it never had a chance to get funky and about 70% of the junk was back flowed out.
It’s been almost three weeks and no bottle fermentation so far.

Update , after a couple months the filtered wine has begun to slightly ferment in the bottle. No more trials like this. I have about thirty bottles that need to be drunk very soon. So my neighbors will be getting bottles of wine tomorrow.
Did you re-filter it or just go with the wine that was filtered a month previous?
And more importantly does it taste OK? If so, tell your neighbors that it's plum lambrusco...
I did not refilled it. It tastes ok, the plum wine lost some flavor. The wine might be ok, there’s hardly any sugar in it.
