Coffee addict here too. The best I've ever tasted were Jamaican Blue Mountain and Kona. That's some smoooooth coffee.
But for the campfire nothing beats the big blue enameled pot. Bring the water to a rolling boil first. Dump in a good amount of any cheap caned coffee and sit the pot just close enough to the fire to keep in simmering. When it looks dark enough for you add a pinch of salt to smooth out the bitter, pour about half a cup of cold watter slowly into the pot to settle the grinds. It does not get better than boil pot coffee at the campfire.
