Do you mean do that to avoid carrying a stove? That might be a reasonable choice for some who do not want to cook or heat water, but carrying cook stuff is not exactly a crushing burden.

Those hints are great for someone who doesn't want to bother with coffee and is caffeine addicted, but for those who just like coffee they miss the mark.

I do tend to not bother with coffee in camp and do without except when I can stop for it, but that is because I don't want to bother, preferring to break camp more quickly. That said I don't see why someone would go without some means of cooking or at least heating water unless they just plain don't want to cook. My cook set in its basic configuration is 10 ounces and it is included in my 8 pound list. If that is too much it isn't that hard to make a 4 ounce cook set using pop can stove and Fosters can pot.
