I grin a little everything some new gadget comes out for making good coffee in the backcountry. As with many things, the original method is still the best, and in this particular case has the added benefit of requiring no equipment at all, aside from the pot, stove or fire, and ground coffee you already have. Like pitching a tarp so you’ll stay dry in a storm, digging a cathole, gutting a fish, navigating off-trail, or building a fire after an all-day rain, making cowboy coffee may seem intimidating at first, but is actually quite simple. Unlike those other things, you can get 90% of the way from cowboy coffee newb to expert without leaving your house. It’s a skill that, given coffees performance enhancing qualities, should be considered as essential as knowing to piss downwind.
First start with a generous amount of grounds and some cold water. As many wise folks have said, you don’t need nearly as much water to make coffee as most people think. Fine grounds are advantageous when making cowboy coffee, they saturate faster and easier, which is the key to their reliably sinking. I bring espresso ground beans, but there is nothing wrong with turkish either.
Combine grounds and cold water and set it to boil. You want to give the grounds as long as possible to saturate and get heavy, as well as impart good flavor to the liquid.
Bring to a roiling boil, and keep it there for 10-15 seconds. On most camp stoves doing this without boiling over will require a less than full pot, as well as hovering the pot over the burner using a grip, pliers, or a glove/sock.
Let the pot rest for a minute. There are many ways, like adding a squirt of cold water or tapping the edge, to help the grounds settle, but if you’ve done the above and have a bit of patience this issue should take care of itself.
Drink. You can decant from the pot into mugs/cups/bottles, or drink straight from the pot. Obviously, don’t swirl or otherwise seriously disturb the coffee, or attempt to pour or drink the last few ounces at the bottom.
This is the best, and simplest, and lightest, way to get a solid cup of coffee in the backcountry. And often a good way to impress friends and neighbors. Practice a bit at home, and you’ll be set to go.
