Another option for those of you who like good coffee, but are constrained by time or weight restrictions: the Melitta filter system.

You probably will have to pre-grind your coffee, but the result is nearly as good as drip. Since you started with better beans (I hope), the coffee is much better than fresh Starbucks. Takes about 5-10 minutes for a pot once the water is boiled - sort of a manual version of Mr Coffee.

Yet another option is Arabic coffee. There are a number of variations, but all start with very finely ground coffee and cold water, brought to the boil. Then either simmer for 20 mins, or spoon off the froth right away and serve, or spoon off the froth and bring back to the boil and serve. The taste is different, just as perked coffee tastes different from drip which tastes different from French-pressed.

Me? I usually drink tea when canoeing or backpacking.
