I have been trying to filter wines using the whole house filter method for a couple of years now. When I have a crystal clear wine I presumed it has worked well as it seemed to shine the wine up. But more often than not I find filtering with a whole house filter to fail.
Occasionally I will filter a wine that has a slightly detectable cloudiness. When filtering the result looks like there is barely any noticeable change. I thought the problem was the filters with the plastic center damaging the seal on the filter housing. So I got all new filters and new filter housings. I tried to filter my rhubarb wine today using a P1 filter without the center plastic with a new filter housing. Once again, the wine came through without any noticeable difference (it was just so very slightly hazy before and after). And when I got to the end I purposely let a bit of fine sediment flow through to see if it plugged the filter. I had no change in pressure and the sediments went immediately right through the filter. This is a 1 micron filter. I checked the filter afterwards and it looks like there was a clean seal imprint on both ends. So it does not appear to be leaking around the edges of the filter. Or maybe it does!?!
I just don't trust this method to filter wine.
