What to check first

Brewer type and filter type

In this scenario, you’re improvising the “brewer” and “filter.” The “brewer” is essentially the vessel holding the grounds and directing the water, while the “filter” is the paper towel doing the heavy lifting.

Water quality and temperature

Use the freshest, cleanest water available. If you’re in an emergency, tap water is likely your best bet, but if you have access to filtered water, use that. The ideal temperature for brewing coffee is between 195°F and 205°F (90°C to 96°C). Avoid boiling water, as it can scorch the coffee grounds and lead to a bitter taste. Let boiling water sit for about 30-60 seconds before pouring.

Grind size and coffee freshness

For this method, a medium to coarse grind is preferable. If your coffee is too finely ground, it will likely clog the paper towel, leading to over-extraction and a muddy cup. Freshly ground coffee will always yield a better flavor, but in an emergency, pre-ground coffee will suffice. The fresher the coffee, the more vibrant the flavor will be, even with this makeshift method.

Coffee-to-water ratio

A good starting point for a standard cup of coffee is a ratio of 1:15 to 1:18 (coffee to water by weight). For a typical 8 oz cup, this means roughly 15-20 grams of coffee. Since you’re improvising, aim for about 2 tablespoons of ground coffee per 8 oz of water. You can adjust this to your taste, but starting with a balanced ratio will give you the best chance of a decent cup.

Cleanliness/descale status

While you’re not using a traditional machine, cleanliness still matters. Ensure the container you’re using to brew into (your mug or carafe) is clean. Also, make sure your hands are clean before handling the paper towel and coffee grounds. Any residue or dirt can transfer to your coffee, affecting the taste.

Step-by-step (brew workflow)

1. Gather your materials. You’ll need a heat-resistant mug or carafe, a few sheets of sturdy paper towel, ground coffee, and hot water.

• What “good” looks like: All necessary items are within reach and ready for use.
• Common mistake: Forgetting a crucial item, like a way to heat water or a container to brew into.
• How to avoid it: Do a quick mental checklist before you start.

2. Prepare your makeshift filter. Take 2-3 sheets of paper towel and fold them in half, then in half again to create a cone shape.

• What “good” looks like: A sturdy, multi-layered cone that can hold its shape.
• Common mistake: Using only one layer of paper towel, which will tear easily.
• How to avoid it: Double or triple up the paper towels for added strength.

3. Position the filter. Place the folded paper towel cone into the opening of your mug or carafe. You may need to gently shape it to fit snugly.

• What “good” looks like: The paper towel is secure and won’t easily fall into the mug.
• Common mistake: Not securing the paper towel well, causing it to collapse or spill grounds.
• How to avoid it: Tuck the edges of the paper towel around the rim of the mug, or use a rubber band if available to hold it in place.

4. Add coffee grounds. Spoon your desired amount of coffee grounds into the paper towel filter. For an 8 oz cup, start with about 2 tablespoons.

• What “good” looks like: The grounds are evenly distributed within the paper towel cone.
• Common mistake: Overfilling the filter, which can lead to grounds escaping or the water not flowing through properly.
• How to avoid it: Leave some space at the top to prevent overflow when pouring water.

5. Bloom the coffee (optional but recommended). Pour just enough hot water over the grounds to saturate them. Let it sit for about 30 seconds.

• What “good” looks like: The coffee grounds puff up and release gas (CO2), indicating freshness.
• Common mistake: Skipping this step, which can result in a less flavorful and more sour cup.
• How to avoid it: Be patient and let the initial wetting phase work.

6. Begin pouring water. Slowly and steadily pour the remaining hot water over the coffee grounds in a circular motion.

• What “good” looks like: Water is dripping steadily into the mug below.
• Common mistake: Pouring too quickly or too much water at once, which can cause the paper towel to overflow or tear.
• How to avoid it: Pour in stages, allowing the water to drip through before adding more.

7. Continue pouring. Keep pouring hot water until you’ve reached your desired coffee volume.

• What “good” looks like: The coffee is accumulating in the mug at a consistent rate.
• Common mistake: Pouring water too high, causing grounds to splash out of the filter.
• How to avoid it: Keep the water level within the paper towel cone.

8. Let it finish dripping. Once you’ve poured all the water, let the coffee finish dripping through the grounds.

• What “good” looks like: The dripping has slowed to a stop, and you have a full mug of coffee.
• Common mistake: Rushing the process by squeezing the paper towel, which can release bitter compounds and pulp.
• How to avoid it: Allow gravity to do its work; patience yields a cleaner brew.

9. Remove the makeshift filter. Carefully lift the paper towel containing the coffee grounds out of the mug.

• What “good” looks like: The filter is removed without spilling grounds into the brewed coffee.
• Common mistake: Dropping the used filter back into the coffee.
• How to avoid it: Lift it out gently and place it aside.

10. Serve and enjoy. Your emergency cup of coffee is ready! Be aware that the taste may differ from conventionally brewed coffee.

• What “good” looks like: A cup of hot, drinkable coffee.
• Common mistake: Expecting a perfect cup; this is an emergency solution.
• How to avoid it: Adjust your expectations and appreciate the fact that you have coffee.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using only one layer of paper towel	Filter tears, grounds spill into coffee, making a muddy, gritty beverage.	Use 2-3 layers of paper towel for adequate strength.
Pouring boiling water directly	Scorches coffee grounds, leading to a bitter, harsh taste.	Let water cool for 30-60 seconds after boiling before pouring.
Pouring water too quickly or unevenly	Causes overflow, uneven extraction, and can tear the paper towel.	Pour slowly and steadily in a circular motion, in stages.
Using finely ground coffee	Clogs the paper towel filter, resulting in slow dripping or no dripping at all.	Use a medium to coarse grind; if only fine is available, be extremely gentle with pouring.
Overfilling the paper towel filter	Grounds can escape over the rim, or the filter can collapse under the weight.	Leave adequate space at the top of the filter for water and grounds.
Not securing the paper towel filter well	Filter can fall into the mug, leading to grounds in your coffee.	Tuck the edges around the rim or use a rubber band to hold it firmly in place.
Squeezing the used coffee grounds	Extracts bitter compounds and paper pulp, making the coffee taste unpleasant.	Let gravity do the work; do not squeeze the filter.
Using old or stale coffee grounds	Results in a weak, flat, and uninspired flavor profile.	Use the freshest coffee available, even if it’s pre-ground.
Using dirty brewing vessel or hands	Introduces off-flavors and potential contaminants into the coffee.	Ensure your mug/carafe and hands are clean before starting.
Expecting a perfect cup	Disappointment with the resulting brew quality.	Understand this is an emergency method; adjust expectations for a functional, not gourmet, cup.

Decision rules (simple if/then)

• If you have a very fine coffee grind, then pour water extremely slowly and gently because fine grinds clog paper towels easily.
• If the paper towel seems to be tearing, then immediately stop pouring and reinforce it with another layer if possible because a torn filter means lost coffee.
• If your water is too hot (just boiled), then wait about a minute before pouring to avoid scorching the coffee because hot water can burn the grounds.
• If you want a stronger cup, then add slightly more coffee grounds to the filter because a higher coffee-to-water ratio will result in a more concentrated brew.
• If you want a weaker cup, then use fewer coffee grounds or pour slightly more water because a lower coffee-to-water ratio will dilute the flavor.
• If you are using a flimsy paper towel, then use at least three layers to provide enough structural integrity because a single layer will likely fail.
• If you notice grounds escaping the filter, then gently adjust the paper towel’s position or add more layers around the edges because this indicates a poor seal.
• If you have a very coarse grind, then you can pour water a bit more freely because coarse grounds are less likely to clog the filter.
• If the coffee is dripping too slowly, then check if the grind is too fine or if the paper towel is clogged because this indicates a brewing obstruction.
• If you want to minimize paper taste, then use a thicker, high-quality paper towel if available because thinner towels may impart more flavor.
• If you are brewing into a wide-mouthed container, then ensure the paper towel is well-supported around the rim because a large opening can cause the filter to sag.
• If you have pre-ground coffee from a store, then assume it’s likely a medium grind and proceed with caution because you don’t have control over the grind size.

FAQ

Can I use a regular paper towel?

Yes, you can use a standard kitchen paper towel, but opt for a sturdier, multi-ply variety if possible. Thin, single-ply towels are more likely to tear and allow grounds to pass through.

Will my coffee taste like paper?

There’s a possibility of a slight papery taste, especially with thinner towels. Using multiple layers and rinsing the grounds slightly with hot water before brewing (the “bloom”) can help minimize this.

Is this method safe for my health?

Generally, yes. Standard paper towels are designed for food contact. However, avoid using paper towels with any added chemicals, dyes, or fragrances, and ensure your brewing vessel is clean.

How much coffee should I use?

A good starting point is about 2 tablespoons of ground coffee per 8 oz of water. You can adjust this based on your preference for strength, but keep in mind the filter’s capacity.

What if the paper towel tears?

If the paper towel tears, you’ll likely get grounds in your coffee. Try to carefully remove the torn filter and start over if you have enough materials. If not, you may have to endure a gritty cup.

Can I reuse the paper towel filter?

No, paper towels are single-use. Attempting to reuse them would be unhygienic and ineffective for brewing coffee.

What kind of coffee grind is best?

A medium to coarse grind is ideal. Finely ground coffee is more likely to clog the paper towel, leading to a slow brew or overflow.

What temperature should the water be?

Aim for water that is just off the boil, around 195°F to 205°F (90°C to 96°C). Boiling water can scald the coffee grounds and create a bitter taste.

Is this better than instant coffee?

For many, yes. While the brewing process is less refined, it uses actual coffee grounds, which generally results in a more complex and satisfying flavor profile than instant coffee.

How do I clean up afterward?

Carefully remove the paper towel containing the used grounds and dispose of it. Rinse out your brewing vessel.
