>>6080513 in one vietnamese instant coffee. probably the cheapest, lightest way to go. Just go to any asian supermarket. You just better like sugar and creme added but I'm telling you its the best option for strong easily toted coffee. Vinacafe or nescafe recommended. About $5 for 20 packets.
Cowboy coffee is something that's great if done right but most people don't do it right. I used to work at a historical park where some actual retired cowboys would make some every sunday morning and man was it good.
The french press idea is also a decent way to make a single cup of espresso. I find it incompatible with my views on camping though. Just a touch too much trouble.
