Other Tips
Unless you plan on boiling the water for 5 to 10 minutes before you do any brewing, you should never use any water found outdoors (rivers or streams). Heating water just to the boiling point is never enough to purify it.It's much better to use the fresh water you are carrying, so plan on bringing enough for coffee as well as plain drinking. Pack your grounds in a tightly covered container to make sure they don't absorb any moisture. There are portable coffee grinders available if you want to grind fresh beans while out on the trail but that is usually a bit more work than most campers want to commit to.
