How to Brew Coffee with a Paper Towel (the DIY Pour-Over Hack That Actually Works)
If you've run out of coffee filters, this works. It's not a permanent substitute for a proper pour-over setup, but in a pinch — a guest shows up, the filter box is empty, and you don't want to drive to the store — a paper towel can brew a clean cup of coffee.
This is the method. The ratio, the grind size, the pour pattern, and the one thing it doesn't do as well as a real filter.
What you need
- Paper towels (unbleached, plain — no prints, no scents, no dyes)
- A mug or carafe
- A bowl or second mug (for the drip-through step)
- 20 grams of ground coffee, medium-fine grind
- 320 grams of water just off the boil (about 200°F)
That's it. No special equipment. The whole setup takes about 4 minutes.
The setup
Take two paper towels and fold them together to create a double layer. Place them over the top of your mug or carafe, pressing down in the center so they form a shallow well. The paper towel acts as your filter.
Some people use a rubber band to keep the paper towel in place on a wider-mouthed container. For a regular mug, the paper towel will stay put on its own if you press it firmly into the opening.
The double layer matters. A single paper towel can let coffee grounds through, especially with finer grinds. The double layer slows the flow and catches more sediment.
The pour
- Heat the water to just off the boil. If you don't have a thermometer, bring the water to a boil and wait 30 seconds before pouring.
- Bloom the coffee. Pour just enough water to saturate the grounds — about 40 grams. Wait 30 seconds. The grounds will bubble as carbon dioxide releases.
- Pour in slow circles. Pour the remaining 280 grams of water in slow, concentric circles, starting from the center and moving outward. Don't pour directly on the paper towel edge — concentrate the pour over the grounds.
- Let it drain. Total brew time should be 3 to 4 minutes. The paper towel will drip slowly. Don't squeeze it.
That's the method. The cup will be slightly different from a paper-filtered pour-over — see below — but it'll be clean and drinkable.
Why this works
A paper towel is, mechanically, a filter. It has fibers that trap solid particles while letting water and dissolved compounds pass through. The reason coffee filters work is that the pore size is small enough to catch most coffee grounds but large enough to let the water-soluble coffee compounds through.
Paper towels have a similar structure. They're made to absorb liquids without breaking down. The pore size is slightly larger than a paper coffee filter, which means slightly more sediment gets through. But for a one-time hack, the cup is clean.
What you lose vs a real filter
The paper towel method has two real trade-offs:
- Body. Paper filters — particularly high-quality ones — trap oils. A paper towel is more absorbent, which means it pulls more of the coffee oils out of the brew. The cup will be slightly thinner and brighter than a V60 or Chemex pour-over. If you like a heavier-bodied coffee, you'll notice.
- Sediment. Even with a double layer, a paper towel will let through a small amount of fine sediment. It won't be gritty, but you might see a slight cloudiness in the cup that wouldn't appear with a real filter.
For most people, neither of these is a deal-breaker for an emergency cup of coffee. For people who are very particular about their cup, it's a backup method, not a primary one.
The grind size matters more here
With a proper pour-over setup, the filter and the brewing vessel are calibrated to work with a specific grind size. The paper towel method has more variable flow, so the grind size matters more.
- Too fine and the paper towel will clog, the brew will run long, and the cup will be over-extracted.
- Too coarse and the brew will run fast, the water won't extract enough, and the cup will be thin and sour.
Aim for medium-fine — slightly finer than table salt. If the brew is taking longer than 4 minutes, your grind is too fine. If it's finishing in under 2 minutes, your grind is too coarse.
When this is the right answer
The paper towel method is for when:
- A friend or partner wants coffee and you've run out of filters.
- You're traveling and the hotel room has a coffee maker but no filters.
- The power's out and you're brewing on a camp stove.
- You want to test a new coffee without committing to your full pour-over setup.
It's not for daily use. Paper towels aren't food-grade filters, and the long-term paper taste can show up in the cup if you brew this way often.

One safety note
Don't use paper towels with bleach, scents, dyes, or printed patterns. Plain unbleached paper towels are the safest choice. If you only have printed or scented paper towels in the house, wait and get filters.
The chemicals used in printed or scented paper products aren't meant for brewing. They can leach into hot water. Even at low levels, the taste will be off and the safety profile isn't what you'd want for a daily brew.
What to drink instead if you have filters
If you have filters and just want a great cup of pour-over, the standard method is the same as above — just with a real filter. We've written about how to brew pour-over step by step for the full version.
And if you're ready to upgrade from paper towels, a plastic V60 costs about $5 and 100 filters cost about $5. That's 200 cups of coffee before you're at the cost of one café visit.
Brew slow. Sip slow.

P.S. The paper towel method also works for steeping tea in a pinch. Same setup, longer steep time (3 to 4 minutes for black tea, 2 to 3 for green). It's not as elegant as a tea infuser, but it gets the job done when you need it to.
A note on paper quality
Not all paper towels are the same. The cheap single-ply ones from gas stations are too thin — they tear when wet and let sediment through. The thicker two-ply or three-ply versions from name brands are more reliable.
If you're using the paper towel method regularly, look for unbleached, two-ply versions. They hold up better in hot water and produce a cleaner cup. Avoid anything with patterns, fragrances, or dyes — those chemicals don't belong in your coffee.
The structure of the paper matters too. Paper towels are made of long fibers that have been pressed together. The pressing creates a relatively uniform pore structure, which is what makes them effective as filters. Some paper towels are more "textured" than others — these tend to let through more sediment. The smooth, dense versions work better.
When to stop using paper towels
If you find yourself reaching for paper towels more than once a month, it's time to invest in a proper filter setup. The cost is low (a plastic V60 is around $5; 100 filters are around $5), and the cup quality is meaningfully better.
We use paper towels maybe twice a year — usually when a guest is in town and we've run out of filters unexpectedly. For daily brewing, we use a ceramic V60 with paper filters. The cup is noticeably cleaner, and we don't have to think about whether the paper towel will hold up.
If you travel with a pour-over setup, the V60 also fits in most suitcases. We've written about what replaces a gooseneck when brewing pour-over for travel-specific setups.
The chemistry of why paper works
Paper is cellulose — long chains of glucose molecules bonded together. When hot water passes through paper, the water doesn't dissolve the cellulose (which is why paper towels don't disintegrate in your cup). The water passes between the cellulose fibers, carrying dissolved coffee compounds with it. Solid coffee grounds are too large to pass through the gaps between fibers, so they're trapped.
The size of the gaps determines what gets through. Paper coffee filters are designed with specific pore sizes for coffee brewing. Paper towels have similar pore sizes, but with more variation. That's why a paper towel lets through slightly more sediment than a coffee filter — same mechanism, less precision.
If you've ever wondered why paper filters turn brown after brewing but don't disintegrate, this is why. The coffee compounds stain the paper. The paper itself stays intact.
