I would recommend tea over coffee - for the reasons stated already plus tea bags are just easier to deal with. Making one or two sometimes 3 cups with each bag vs. handling grounds.

Another is just personal preference. I like Earl Grey; about 1/2 the caffeine as regular coffee BUT it doesn't make me run to the washroom as frequently and when I am camping I really appreciate that! <img src="/images/graemlins/smile.gif" alt="" />

Soup bouillon is even better from a nutrition point of view.
