I can certainly camp without it but coffee makes a cold morning oh, so much better!
A great cup of Joe takes the nip off the morning, puts hair on your chest and keeps
you awake during a 20-mile hike - well, at
least on the downhill part!
Great Coffee versus Good Coffee, once you had this espresso, oh my hello, it really gets better!
I bought once in REI these packets with concentrated liquid coffee, and found it very bad tasting...so, I carry only instant coffee with me... I always admired people who carried espresso set up with them...
