So youre using water filters and adding the DE.. Yes, it has to be a one
shot deal, if your not sanitizing and sterilizing the filter it will go bad
after that use. Why are you concerned with filtering yeast? Doesn't your
primary and mlf (assuming you do it) fermentation take care of that? If
not, it should precipitate when it cold settles so racking will remove the
remainder. Annnnnd, if that didn't work (lol), there is the meta additions
at each racking... :)
Also, I would think too much pressure is bad, it stirs up the wine in the
bottle too much, assuming your bottling.
I have tried just a plain water filter, but it takes about 10 gallons before
it is 'ready for use', for wine. Also, once the water has removed the
plastic-y smell and primed the filter, you have to run a decent amount of
wine through to make sure youre not diluting it.
As youre repalcing your filter after every use, and each filter runs about
$10 I guess, plus the minimal cost for the earth, don't you think it would
just be cheaper to buy a sanitized filter to start? My filters run $80, last
3 years, and the bottle of sterilizing cleanser, which is only a few bucks,
Thanks for the info though, looks like it could be a good idea for large
rackings, if I decide to filter then, esp since plate filters cost so much!
