The bag thing would probably work, but socks? After a few days on the trail, there just ain't no clean socks . Ya wear the oldest used, rotationally, but they ain't clean - they're just somewhat dried out . Serious camping don' 'low for nothin' clean .no no no no no no no!
Not socks you packed to wear on your feet! And by clean I don't mean washed...I mean never worn...ever. You need a coffee only sock
. This is an unused, 100% mercerized white cotton sock of a very tight knit that will act as a good filter for the grounds. There is an art to selecting the right sock. It's not the same as selecting socks for your feet. A brand new white cotton dress sock with a tight knit will work well, but a gym sock is useless, as it will let the grounds right through.
Once you have the one you will be using, it's just for coffee...you never ever
put it on your feet! Just keep using it for coffee only, and over time it will make the coffee taste even better, as it ages. Yes, it will look like hell as the coffee stains it and the fibers become embedded with the residues of the coffee oils, but that is what actually makes your coffee better, I have been told. When you are done using it, you dump the grounds, turn it inside out and rinse it well, by hand. Then wring it out good and hang it to dry. Don't ever
throw it in the laundry with any sort of detergent or bleach or you will end up with residues from that in your coffee.
It's one of the secrets to the great coffee that some of my Puerto Rican friends made, in my old neighborhood.
The first time I ever saw one of them making coffee I thought "ewwwwww! I am not drinking that! I don't want your athletes foot coffee! Don't be so ghetto...buy some filters!" But then it was explained to me that the sock was carefully chosen just for brewing coffee and had never been worn on anyone's foot, and if anyone ever tried to wear it or wash it in the laundry, her mom would kill them because a good coffee sock is hard to find. (luckily, they come in pairs)
