CAMP COFFEE — The Foxhole Recipe

Percolator and cowboy method. No excuses, no electricity.

This is the Foxhole sweet spot. You don’t need a drip machine, a gooseneck kettle, or a scale. You need fire, water, and beans. The percolator and cowboy methods both work with the same basic principle: immersion extraction with heat, finished with a strain. Neither method will produce the most technically precise cup. Both methods will produce a cup that’s hot, strong, and ready when you are. That’s the mission.

Difficulty: Field Expedient Time: 7–10 min percolator · 5 min cowboy

Gear List
  • ✓ Percolator OR any heat-safe pot
  • ✓ Open fire, camp stove, or any heat source
  • ✓ Coarse ground coffee
  • ✓ Heat-safe mug or cup
  • ✓ Timer (or count)
  • ✓ Cloth or bandana to strain (cowboy method)
Quick Stats
Grind

Coarse · like raw sugar (percolator) or extra coarse (cowboy)

Ratio

1:12 to 1:15 · stronger is easier to manage in the field

Water Temp

Just below boil · percolator self-regulates

Brew Time

7–10 min percolator · 5 min cowboy

Step by Step

The Recipe

1

PERCOLATOR METHOD — Fill the bottom chamber with cold filtered water. Use 1 heaping tablespoon of coarse ground coffee per 6oz of water

2

Add grounds to the basket. Don’t pack — leave room for water to circulate through

3

Assemble the percolator and place over medium heat (camp stove) or at the edge of coals (open fire)

4

Watch for the perk — you’ll hear and see liquid cycling through the glass knob. Once perking starts, keep it at a slow perk for 7–10 minutes. Aggressive boiling = bitter

5

Remove from heat. Let sit 90 seconds for grounds to settle. Pour carefully — don’t disturb the settled grounds at the bottom

6

COWBOY METHOD — Bring water to just below boil in any pot. Remove from heat

7

Add 2 heaping tablespoons of extra-coarse grounds per 12oz of water directly to the water. Stir once

8

Steep 4–5 minutes. Don’t stir again — you want grounds to settle, not stay suspended

9

Slowly pour through a bandana, cloth, or fine mesh into your mug. Pour from height to let the stream aerate. Leave the last inch of sludge in the pot

Troubleshooting

Dial It In

Problem Fix
Bitter — percolator Reduce heat. Percolating too hard at a rolling boil over-extracts. Target a slow, steady perk — not aggressive bubbling. 7 minutes at low heat beats 5 minutes at high
Weak / Sour More coffee or longer extraction time. Field expedient: just use more beans. Stronger is easier to dilute than weak is to fix
Muddy / Grounds in cup Let it sit 2+ minutes before pouring. Pour slowly. Leave the last third of the pot — that’s where the mud lives. Cowboy method always has some sediment; that’s correct
No heat source strong enough Pack a small camp stove or solid fuel tabs. A campfire works but requires more attention to keep percolator at a slow perk and not a rolling boil
No filter / no strainer Cowboy method without a filter is fine — just let grounds settle for 3+ minutes and pour slowly from height. A cotton bandana works. So does a hat
FAQ

Common Questions

Q: Percolator vs cowboy — which is better?

Percolator if you have one — it self-regulates temperature and gives you a more consistent result. Cowboy if you don’t have equipment. Both work in the field. Cowboy has a longer history and requires fewer parts.

Q: What grind size for a percolator?

Coarse — like raw sugar. The long extraction time compensates for the coarser grind. Fine grind clogs the basket and produces bitter over-extraction.

Q: How do I stop grounds from ending up in my cup?

Two things: coarser grind and patience. Let the pot sit 2 minutes off heat before pouring. Pour slowly from height. Leave the last inch of the pot — that’s where the grounds settle.

Q: What Foxhole roast works best for camp coffee?

Daybreak and Reveille hold up best to field conditions — medium and medium-dark roasts are more forgiving of temperature variation and longer extraction. Light roasts need more precision to taste good.

Q: Can I make cowboy coffee with pre-ground?

Yes. Pre-ground works fine for both methods — just use a coarser pre-ground if you can find it, or accept some sediment. The method is designed for rough conditions. Don’t overthink it.
