Since I'm a stickler for a good cup 'o joe, I've tried just about every imaginable method for backcountry brew. Here's a quick run down on how to get the best caffeine fix on your next multi-day trip.
GSI Java Press

GSI Outdoors--maker of all sorts of camp kitchen equipment--makes a Lexan Coffee press that comes in 10oz, 33oz, and 50oz sizes. Add a tbsp of coarsely ground coffee to the press. Pour boiled water (but allow it to rest a bit to come down in temperature) from your campstove over the grounds so they are completely saturated as you fill the press to the fill line. Let it sit a bit until a foamy "bloom" forms on the top. At that point, plunge the filter down slowly and steadily. Then pour your cups.
Drawbacks
You get great flavor, but there's a price to pay. First, is output. Even the 50oz size will only produce roughly 4 12oz cups of coffee. If you're in a group, you'll be serving in batches. Another problem is the waste generated. Grounds need to be scooped out, then packed out with your garbage. The Press itself doesn't weigh much, but does take up some space, an issue if you're low on storage space in your kayak.

The Coffee Sock

Drawbacks
Flavor tastes like coffee from a sock. Clean up is a pain, and you have to pack out your spent coffee grounds.

Single Cup Filters

Drawbacks
Better flavor than a coffee sock, but the single serving aspect means that unless everyone in your group has their own filter, there will be a queue of caffeine-deprived campers staring at you as you prepare your brew.

Output to Effort Ratio = B
Brew Bags
Brew Bags are teabag style filters that can be purchased in the coffee aisle.
Just like tea, you simply boil water and jiggle the bag in the cup. One brew bag per cup.
Drawbacks
Flavor is terrible. This is partly because the method doesn't bring out the best in the coffee, but also because the companies that produce the stuff tend to make pretty flavorless coffee to start with. If you like watered-down coffee of the ilk that you get in the waiting rooms of your local tire store, then you'll be happy with this stuff.

Cowboy Coffee
Forget filters. Simply pour coffee into a pot of boiled water and let sit. Methods for filtering out grounds range from dropping a little cold water over the top to force grounds to the bottom of the pot; "slinging" the coffee pot (this works only with a proper tea kettle with a lid and handle) in wide circles so that centrifugal force pushes the grounds to the bottom; or pouring through a bandanna.
Drawbacks
Tastes like boiled coffee, with the added joy of picking out grounds from your teeth for the duration of the morning. Clean-up and plenty of waste produced. Also, pouring off hot water, filtering through a bandanna, and especially "slinging" all come with the potential for second-degree burns. Blatant sexism: don't cowgirls drink coffee too?

Instant Coffee: Mt. Hagen Organic v. Starbucks Via

Method
Mt. Hagen, add a teaspoon to a cup of hot water and serve. Starbucks Via comes in single serve pouches.
Drawbacks
For Mt. Hagen, the flavor is better than every other method except the French Press. For Starbucks, the flavor--in my opinion--is better than all the other method; price is the only drawback. Each cup will cost you $0.83. Not bad compared to the $1.75 you'd pay for a cup at Starbucks, but still much higher than the $0.13 per cup for Mt. Hagen.
Grade
Ease of Use = A+
Flavor Factor = Mt. Hagen: B+ v. Starbucks: A
Quick Clean-Up = A+
Output to Effort = A
Conclusion
For my trips I'm now leaving the French Press behind and packing in Starbucks Via. With the weight and space I'm saving, I'll be able to have room for an extra bottle of wine...but that's a subject for a future blog.
Happy paddling!
