Coffee filters: a question

Natural materials such as cotton and natural rawhide fit here. But it could be dough or water too.

Coffee filters: a question

Postby Odin » Mon Feb 27, 2012 7:58 am

I usually filter thru brown "unbleached" (hope that's spelled correctly!) coffee filters, after aging on wood. Now the mss bought some white bleached coffee filters. Are these suitable or does the bleaching transfer unwanted taste components?

Any experience, thoughts?

I use them all the time, since I already had a shit load on hand. Never noticed any difference in taste from unfiltered to filtered, but I never tried the brown unbleached ones.

I'm so bad now... I age on chips and they don't make much of a mess in my jars, i don't even bother filtering anymore from the ageing vessel to the bottle.

Now don't get me wrong, if i'd have a dusty brown mess at the bottom of my ageing jars, i would definitely filter it down.
It aged on the way out of the worm. :mg:

I use whatever I have on hand no problem other than they always seem to plug well before I am done especially with the raspberry liqueurs that have been aging in a cheese cloth. Solved the problem with my vacuum filter set-up.

I don't know about alcohol, but white paper makes better coffee. Try pouring boiling water through the filter papers and tasting. Brown filter paper gives more of a cardboardy taste.

Most of the difference between them is actually due to the quantity of residual lignin in the paper fibres which is about 5x greater in the brown filters. Bleaching (typically usually using peroxide) is used to whiten the remaining lignin.

Almost all my alcohol gets left for long periods with chunks of wood in it though, so what's a bit of extra lignin :wink:

Coffee filters are a bit coarse I think, I usually get a fine sediment of charcoal in the bottle. You can get better quality filter paper elsewhere.

I used to have a Buechner funnel for vacuum filtration which would have been the dog's bollocks but I flogged all my lab stuff last year. Schnell had a great idea for making a jumbo Buechner out of 1 1/2 kegs.

I have always used the white filters

when doing a stripping run I put a filter in the funnel inbetween the output and collection jug.

and always filter after ageing when botling also,

have noticed how the colour of the product changes after filtering at bottling

I use both, haven't noticed a difference. For coffee I rinse the filter with hot water but I don't bother for booze. Maybe time for a side-by-side test here.

Yeah! The same here. Filters get so clogged, they hardly let any liquid pass after some time ...

I have always used Webril wipes for my filtering. They seem to catch the smaller stuff better for me. Plus I can get the free...

I have found it harder and harder to find unbleaced filters around here. Everyone use to carry them. Now I only know of one health food type store that sells them. So I just use the white ones.

Hey bushman. How's that filter working for you? It's still on my build list. That I will get to one of these days? :screwy:

I built this specifically for the white coffee filters. I usually put a piece of cloth the shine drops on first, them on through to the filters.

Squint....

looks much like my setup. I use a large hand "sieve" i think is the term, to hold my filter and pour through it into a glass measuring cup.
