For the past few years I have been on a search for the best "camp coffee". I brew my own at home and have tried, with some success to do this on the trail. I have been in search of a good a lightweight system.
Cowboy coffee is hard to get right and gets messy, so far I have not found an instant coffee that I can drink, and the french press systems weight too much.
I currently use a filter that fits into my nalgene bottle. Works great, but I was wondering what everyone else does.
