well I don't know if this would work for you and the kind of coffee you drink, (we use Puerto Rican coffee) but I use a
coffee sock to make coffee at my place of business, since I don't have electricity there for a coffee maker. Basically I make coffee like this:
1) Measure out 6 oz of water for every serving of coffee.
2) Boil the water.
3) Measure out 2 Tbsp grains for every serving of coffee.
4) Add coffee grains to boiling water, stir, turn off heat and cover for 5 minutes.
5) Stir again, then pour contents into coffee sock. You can brew directly into your mug, thermos, etc.
6) Discard grounds, then wash the sock with dish washing liquid and water until clean again.
The resulting coffee is delicious (according to my mother the coffee aficionado, and the customers). There is no paper filter taste, and at least with Puerto Rican coffee, you can save coffee made this way for the next day and reheat it with no loss of flavor. My mother the "reheated coffee is gross" person never knew that I served her reheated coffee. And she is one that can tell you if the coffee was made in a pot with a sock, in a coffeemaker, one of those dispensing machines, etc. She's very picky.
