Two stage home brew beer filtering question….?


I’d like to start filtering my brew with both a 5 mic and a 1 mic filter, but I was curious if I could filter it with both filters in line instead of one at a time.

You can if your system is design for it. Most home brewing filter systems require us to do two flirtations if using different filter pads-aids. I have seen a friend try the two pads (3 and 1 micron respectively) and it became clogged. That is not to say that it would have clogged if he hadn’t combined them but he just does two separate filter runs now.

For those that may not know why filtering helps consider this. If you’re like me, you commonly have problems with haze in your finished beer. Seems that no matter what I do – Irish moss, gelatin finings, polyclar, etc. – I still end up with beer that’s not a bright as I’d like it. Some brewers make beer that becomes crystal clear; I envy them. Others say that if haze really bothers you, you should drink from an opaque mug or just close your eyes.

Haze in your finished beer can come from many sources, including the yeast (which imparts a permanent haze, no matter what the beer temperature). Larger proteins that are not metabolized by the yeast can remain in suspension, dissolving in the beer at certain temperatures but coming back out of solution when you chill the beer – that’s chill haze.

I don’t intend to go into great detail about what causes haze and what the different kinds are; you can refer to a number of recently published articles and/or homebrewing texts for that information (see references above). The important thing to note in this context is that filtering to 5.0 microns will remove most of the yeast; filtering to 1.0 microns will remove many haze causing particles in your beer; filtering to 0.5 microns will remove nearly all chill haze causing proteins as well. Filtering below 0.5 microns can have detrimental effects on your beer, as many of the vital components of the body, flavor and head will be removed. I’d encourage you to experiment with different micron ratings and see which you like best; I personally can’t taste any difference {well sometimes} in unfiltered beer and beer filtered to 0.5 microns.

Drinking is the Devil!

idk but that is a good answer because it seems reasonably that the two things are separate so two turns art filtering is needed.


As for me I know this but I could never put that much effort in an answer. I agree to making it a two trial filtration for the best results.
