Filtration

[egolds77]

I've been using a 1 micron filter, using gravity after a secondary fermentation and the beer is still not cystal clear. I AG brew, don't add finings. I've ordered a 0.35 micron filter element and thinking of filtering using the 1 micron as well as the 0.35 micron element as well in a twin filtration setup, only to reduce the amount of sediment entering the 0.35 elemnt by the 1 mucin element. What are peoples thoughts and practices?

Evening Elton. Is the 1 micron absolute or nominal ? If it's absolute then it should give crystal clear beer.

Don't filter myself, but could the cloudiness be from chill haze rather than sediment?

You could try Polyclar (search sponsors websites, or plenty of pages on here).
I have found this clears my beer beautifully. I just crash chill to reduce sediment.

little from column a, little from column b....theres a hell of a dif between absolute and nominal; alternatively, it could be haze.
pour a sample, and warm it....if it's clear, it's haze. If it's not, it could be either yeast or haze. Chill the sample. If it crashes out the yeast, and is clear, it's yeast. If it has sediment and it's still hazy, then it's both.

fwiw, I think finings should be used, even if filtering...if for no other reason, than to increase the life span of the filter. 2d.

edit...spellinks.

From the few brews i've filtered using the element I'm thinking it might be nominal from what I've heard about 1 microns filtering sufficeintly.

I use the 1 micron absolute but I also crash chill my beers at 0c for five days prior to filtering. They come out crystal clear.


Cheers, Hoges.

Can ask how much you paid for the filter Elton?

 

[egolds77]

It did seem rather cheap at $15 for the 1 micron filter element. I really must read that fine print.

At that price I would think it is nominal. Not all is lost. Just chill the beer close to 0 degrees and use Polyclar. I would think you will get a very clear beer.

Thats the one!

Chill it. This makes any potential chill haze form and makes it a lot easier for the filter to catch..

Also, invest in a 1 micron absolute filter cartridge from one of the site sponsors. They won't sell you something that won't work.

cheers

I filter, but don't fine.

Best way to ensure clear beer is CC at 0C for at least 4 days. I've never had a hazy beer this way. I previously used to crash chill overnight, then filter. The beer went into the keg crystal clear, but a haze forms after a couple of days.

The cartridge could be an issue as well, as mentioned.

I tried a new beerbelly 1 micron on a lager which had been chilled on the weekend. By gravity from the fermenter.

Only problem was the lack of a bleed valve meant I had to loosen the top of the filter to get the air out - it let a bit of unfiltered into the filtered so got a bit of $%^& go into the keg when I did it.

50-60 bucks for a 1micron absolute, $90-95 for a .05 from my source in Hobart. A tip for what its worth the clearer the beer before filtering the better the result and the longer your cartridge will last. IMO clear beer starts from the boiler.

I guess based on that mine must be nominal as the element in the BB unit is fairly cheap. It did the job though.
