How to Make Coffee Using the Boiling Method

If you’ve ever wondered how people made coffee before espresso machines or pour-over cones existed, the answer is simple: they boiled it. The coffee boiling method is the oldest known way to prepare coffee, dating back centuries. It’s still used today in places like Turkey, and it’s surprisingly effective—if you get the details right.

To make five servings using the classic boiling method, you’ll need 650 millilitres of water and 40 grams of lightly coarse-ground coffee. That’s a brew ratio of roughly 16:1. The process involves boiling, stirring, resting, and filtering—but timing and heat control are everything.

What Is the Coffee Boiling Method?

The coffee boiling method is one of the most primitive ways to brew coffee. It involves combining ground coffee and water in a pot, bringing it to a boil, and then filtering the liquid before drinking. Unlike modern methods that focus on precision extraction, this technique relies on prolonged contact between coffee grounds and hot water, often resulting in a strong, robust cup. Turkish coffee is the most well-known example, though it uses a much finer grind.

How to Brew Coffee by Boiling: Step-by-Step

Here’s how to make five servings using the traditional boiling method:

• Start with 650 millilitres of water in a pot or kettle.
• Heat the water until it reaches a rolling boil.
• Once boiling, add 40 grams of lightly coarse-ground coffee (not finely ground).
• Stir the mixture with a bamboo or wooden spoon for about 20 seconds.
• Let the coffee sit off the heat for around two minutes. Allow the foam to settle but do not let it fully dissipate.
• Before the foam completely disappears, remove the pot from the heat to prevent over-extraction.
• Filter the brewed coffee through a filter bag or fine strainer to separate the grounds.
• Return the filtered coffee to the pot and gently warm it up to 88°C (190°F) before serving.

Grind Size and Why It Matters

The grind size for this method is described as “lightly coarse.” That’s coarser than espresso but finer than what many use for French press. Turkish coffee, by contrast, uses a very fine grind—almost powder-like—which creates intense extraction and thick body. For the traditional boiled coffee method outlined here, a lightly coarse grind helps balance extraction without excessive bitterness. Avoid stirring too vigorously, as it can make the brew cloudy and worsen clarity.

Common Mistakes and How to Avoid Them

The biggest risks in boiled coffee are over-extraction and bitterness. Brewing for too long or at too high a temperature leads to undesirable flavours: harsh bitterness, dry astringency (often called “dryness” or “sourness”), and even earthy or muddy off-notes. To avoid this:

• Do not let the coffee boil excessively after adding grounds.
• Stop the extraction by removing the pot from heat just before the foam fully fades.
• Filter carefully to remove all grounds before warming and serving.
• Keep total brew time controlled—roughly 2–3 minutes of active contact time before filtering.

Frequently Asked Questions

What is the coffee boiling method?

The coffee boiling method is an ancient way of brewing coffee by combining ground coffee and water in a pot, boiling the mixture, and then filtering out the grounds. It’s the oldest recorded coffee preparation technique and is still used in traditional forms like Turkish coffee, though grind sizes vary significantly.

How much coffee and water do I use for boiled coffee?

For five servings, use 650 millilitres of water and 40 grams of coffee. This gives a brew ratio of about 16:1. Adjust quantities proportionally for more or fewer servings.

What grind size should I use for boiling coffee?

Use a lightly coarse grind—coarser than espresso but finer than French press. Avoid using a very fine grind unless making Turkish-style coffee, which requires an extra-fine, powder-like consistency.

Why does the foam matter in this method?

The foam that forms during boiling indicates active extraction. You’re meant to let it settle for about two minutes and then remove the pot from heat just before it fully dissipates. This timing helps avoid over-extracting the coffee, which leads to bitterness.

Do I need to filter boiled coffee?

Yes. After boiling and resting, you must filter the coffee through a filter bag or fine strainer to remove all coffee grounds before warming it to serving temperature (88°C or 190°F).

Can I use any coffee for the boiling method?

Technically yes, but the method works best with coffees that can handle intense extraction. Darker roasts or blends with heavier body may perform better than light, delicate single origins, which can taste overly bitter or astringent with prolonged heat exposure.
