I was reading an old thread about clarifying a finished wash, and found this question posted by Seth:
"Can you use a plate and frame filter to remove the suspended yeast, post fermentation, or would this somehow harm the final product?" (no one answered him)
I understand that no one recommends using Sparkaloid or other fining agents...however, is anyone filtering their wash before running it? Plate and Frame may not be the best choice...might there be another type of filter for this? I've read about centrifuges being used for this reason, so that's why I ask.
Cheers,
John

I know Frederic Brewing (now owned by Flying Dog) used a pharmaceutical centrifuge they bought at a industrial auction so they could really manage how little or how much (wheatbeer) turbidity and clarity they wanted.

If for whatever reason you don't want to use filter aids, other than time and temperature, you could chill it down and allow time for Stokes' law to do its thing, then polish it up with a DE filter. Thats what you might do to make beer sparkle, but why no fining aids, and especially, why filter the wash before distilling?

Good question...I am not sure why fining aids are not used. On an older post, a few of the guys were saying that fining agents shouldn't be used at all. I am curious about them, as well as filtering the wash...to remove yeast solids left in the finished wash, as Seth asked a while back.
Thanks for your help guys

I know in the wine world there's wineries using a lees filter which helps seperate all the heavy sediment (yeast, etc.) from freshly fermented wine. Its usually used to minimize loss from the first racking but i have no idea how it would work with a grain based wash.....
