How to Make Coffee During a Power Outage

The lights go out at 6:40 a.m. The coffee maker is dead, the electric kettle is dead, and the grinder is dead. Good news: coffee is older than electricity, and you only need two things, hot water and a way to separate grounds from liquid. This guide shows how to make coffee during a power outage safely, depending on the heat source you have, and what to keep in a cupboard so the next blackout is a minor inconvenience.

One rule comes before any recipe: never bring a grill, camp stove or generator indoors to boil water. More on that below.

Key takeaways

• If you have no safe indoor heat source, make cold brew or use instant coffee dissolved in cold or room-temperature water.
• The CDC warns never to use generators, grills or other gasoline-, propane- or charcoal-burning devices inside a home, garage or carport.
• A gas cooktop, a wood stove designed for cooking or an outdoor camp stove can all heat water for pour-over, French press or cowboy coffee.
• Whole beans can be crushed by hand; a hand grinder and pre-ground coffee in the cupboard make it easier.

Safety first: where you can heat water

Carbon monoxide is the real danger during outages. The U.S. Centers for Disease Control and Prevention tells people never to use a generator, grill or other gasoline-, propane- or charcoal-burning device inside a home, garage or carport, and to keep generators at least 20 feet from doors, windows and vents. The CDC also says not to heat your home with a gas oven.

For coffee, that leaves these options:

If the water is unsafe to drink because of a boil-water notice, follow your local authority’s instructions first. A quick bloom of coffee is not a substitute for properly boiling water.

How to make coffee during a power outage, by heat source

You can boil water: French press, pour-over or cowboy coffee

Any brewer that is not plugged in still works. A French press needs nothing but hot water and four minutes. A pour-over cone with a filter works over a mug. If you have neither, cowboy coffee is the classic: grounds go straight into the pot. Our cowboy coffee recipe covers the settling trick, and coffee without a coffee maker walks through more improvised methods.

A simple ratio that works for any of them: about 2 tablespoons (10 g) of medium-coarse coffee per 6 oz (180 ml) of water. Take the water off the heat and let it rest about 30 seconds before pouring.

You have a moka pot and a gas flame

A stovetop moka pot is a perfect outage tool. It brews over a gas flame or a camp stove (outdoors) exactly as it does on an electric hob. Keep the flame small so it does not lick up the sides.

You have no heat at all: cold brew

Cold brew needs only time. Stir about 1 cup (roughly 85 g) of coarse coffee into 4 cups (1 liter) of water in a jar, cover it and leave it 12–18 hours, then strain through a paper filter, a clean cloth or a fine sieve. That makes a concentrate: dilute it about 1:1 with water. If the fridge is off, steep at room temperature and drink it the same day. Our full cold brew guide has more detail.

You need coffee now: instant

Instant coffee dissolves in cold or room-temperature water. Shake it in a jar with water, milk or a dash of sugar, and you have an iced coffee in thirty seconds. It is the fastest outage coffee there is.

No grinder? Three workarounds

If you keep whole beans and your electric grinder is out, try one of these:

1. Hand grinder: the best option. A manual burr grinder takes a minute or two per cup.
2. Rolling pin: put the beans in a zip-top bag, cover with a towel and crush, then roll. You get an uneven, coarse grind that suits French press, cowboy coffee and cold brew.
3. Mortar and pestle: slower but gives more control for a finer grind.

Uneven grounds extract unevenly, so lean on immersion methods (French press, cold brew, cowboy) rather than pour-over until power returns.

Keep coffee hot without power

Boiling water costs fuel, especially on a camp stove. Make it count:

• Brew one larger batch and pour it straight into a preheated vacuum flask. A good flask keeps coffee hot for hours.
• Fill the flask with leftover hot water too, for a second cup later or for washing up.
• Wrap a French press in a towel while it steeps in a cold kitchen.
• Skip reheating on the flame; it wastes fuel and turns coffee bitter.

A power outage coffee kit

Put these in one box so you are not searching in the dark:

Rotate the coffee in your kit every few weeks so it stays fresh: use it, then restock.

What to stock from Feel Espresso

Our Instant Coffee comes in a resealable pouch of about 30 servings, which makes it an easy kit staple. Cold Brew Coffee is a dark roast blend already coarse ground for cold brew, so it is ready for a no-heat jar brew. And if you want something bold for the French press or the pot on the gas burner, Cowboy Blend mixes dark and medium roasted beans with cocoa and caramel tones. Order any coffee ground Coarse if you will not have a grinder.

Power outage coffee FAQ

Can I use my gas stove for coffee when the power is out?

Usually yes, for normal cooking. Many gas burners can be lit with a match when the electric igniter does not work; check your manufacturer’s instructions. Do not use the oven to heat the house.

Can I boil water on a camp stove inside?

No. The CDC warns against using propane-, gasoline- or charcoal-burning devices indoors, including in garages. Use the stove outside, away from doors and windows.

How do you make coffee with no heat at all?

Make cold brew (coarse coffee steeped in water for 12–18 hours, then strained) or stir instant coffee into cold water.
