The 'World's Smoothest Coffee' Requires No Keurig, Press, Or Percolator

During a recent cross-country move, we survived the long drives making what we called "road trip coffee," dumping grounds in a big thermos of hot water to fill our travel mugs without stopping. This travel solution is similar to classic cowboy coffee, which when done right results in what YouTuber steelpanguy calls "the world's smoothest coffee" — despite not necessarily requiring electricity, filters, or percolators. What most of us know about this cowboy brew — and other cowboy foods from the trail — comes from old movies, evoking visuals of bitter, strong, grounds-filled sludge. If done wrong, this is certainly possible, but it doesn't have to be the case.

If you've only ever used a drip maker or Keurig for your coffee, then your brew is made by running water through the grounds until it slowly pours into your pot or mug. Cowboy coffee is closer to using a French press, where you drop the grounds into the water and let them steep. It also has some similarities to a percolator, where the water boils up into a basket holding the grounds. With cowboy coffee, there is no separate chamber for your coffee, nor is there a plunger like you'd find in a French press. 

The process begins with putting water into a regular old metal pot or a large saucepan. You put the water on the fire or stovetop, drop in coffee grounds, and then serve it to everyone on the trail (or in the house) with you. Simple, right? Well, turns out there's more to it than that. Successful cowboy coffee is all in the details.

The key to traditional cowboy coffee is in the boil. You start with warm water and then drop in coffee grounds and wait for the pot to boil. We're not talking about some light bubbling; you want a rolling boil. This is when the water hits the wall of the pot so hard that it rolls back over itself at a vigorous pace. In a YouTube video by Cowboy Kent Rollins, the leading voice in the art of cowboy coffee, he says you want to keep the rolling boil going for four minutes. These four minutes extract so much flavor that instead of the golden ratio of 1 tablespoon of coffee to 4 ounces of water, you might use only 1 tablespoon of grounds for every 8 ounces of water.

But boil coffee for too long and the grounds begin to release oils and tannins, increasing both the acidity and bitterness. This is why an alternative method has you boil the water without any coffee, then take it off the fire for 30 seconds before adding the grounds and steeping for five minutes or so. Whichever method you choose, the final step when making coffee this way is the one that ultimately prevents a sludgy cup: running a little cold water down the spout of the pot and along the sides creates a thermal shock and pushes the grounds to the bottom. This lets you serve a smooth cup without any grounds to ruin your morning, proving you don't need a French press or an expensive coffee maker. All you need are coffee grounds, heat, water, and a pot for the smoothest coffee you'll ever have.
