What to check first

Brewer type and filter type

Cuban coffee is traditionally made using a stovetop moka pot, often referred to as a “cafetera.” This method uses steam pressure to force hot water through finely ground coffee. Some might also use an espresso machine or even a strong drip coffee maker, though the result will differ in intensity and texture. The filter type is usually integrated into the moka pot itself, a metal filter that holds the coffee grounds. For other methods, paper or metal filters might be used.

Water quality and temperature

Using filtered water is crucial for any coffee brewing, as tap water can contain minerals that affect taste. For Cuban coffee, very hot water is essential, typically just off the boil. In a moka pot, you’ll often start with pre-heated water in the lower chamber to speed up brewing and prevent the grounds from overheating. Aim for water that is between 195°F and 205°F (90.5°C to 96°C) for optimal extraction.

Grind size and coffee freshness

Cuban coffee typically uses a fine to medium-fine grind, similar to what you’d use for espresso. The grind should be consistent to ensure even extraction. Freshly roasted and ground coffee beans will yield the best flavor. Pre-ground coffee can lose its aroma and taste quickly. For a true Cuban coffee experience, look for dark roasts, often with a slight char.

Coffee-to-water ratio

The ratio for Cuban coffee is generally stronger than for standard drip coffee. A common starting point is about 1:10 or 1:12 coffee to water by weight. For example, using 20 grams of coffee for 200-240 ml of water. This is a guideline, and you may need to adjust based on your preference for strength.

Cleanliness/descale status

A clean brewing device is paramount. Coffee oils can build up and turn rancid, imparting bitter and unpleasant flavors to your brew. Regularly clean your moka pot, including all its components, with warm water. If you use other brewing methods, ensure their filters and reservoirs are also free from old coffee residue. Descaling, if applicable to your brewer, is also important for optimal performance and taste.

Step-by-step (brew workflow)

1. Prepare the Moka Pot: Disassemble the moka pot. Ensure the filter basket is clean and free of old grounds.

• What “good” looks like: The moka pot parts are clean and dry.
• Common mistake: Using a dirty moka pot. This will result in bitter, stale-tasting coffee.
• How to avoid: Rinse all parts thoroughly with hot water after each use and dry them.

2. Fill the Base Chamber: Fill the lower chamber with hot, filtered water. Fill it up to just below the safety valve.

• What “good” looks like: Water level is correct and doesn’t obstruct the valve.
• Common mistake: Overfilling the chamber. This can cause steam to escape improperly and affect brewing.
• How to avoid: Use a measuring cup or pour carefully, stopping just below the valve.

3. Add Coffee Grounds: Fill the filter basket with finely ground coffee. Do not tamp the coffee; level it off gently with your finger or a spoon.

• What “good” looks like: The coffee is evenly distributed and level, without being pressed down.
• Common mistake: Tamping the coffee grounds too firmly. This can create too much resistance for the water.
• How to avoid: Gently level the grounds; don’t press them down like you would for espresso.

4. Assemble the Moka Pot: Screw the top chamber onto the base chamber tightly. Ensure a good seal.

• What “good” looks like: The two chambers are securely joined with no gaps.
• Common mistake: Not screwing the chambers together tightly. This can lead to steam leaks and weak coffee.
• How to avoid: Twist firmly until you feel resistance and see no visible gaps.

5. Heat the Moka Pot: Place the assembled moka pot on a medium heat on your stovetop.

• What “good” looks like: Consistent, moderate heat applied to the base.
• Common mistake: Using excessively high heat. This can scorch the coffee and create a bitter taste.
• How to avoid: Start with medium heat and be prepared to adjust it down if brewing too quickly.

6. Watch for Coffee Flow: After a few minutes, coffee will begin to flow into the upper chamber.

• What “good” looks like: A steady, syrupy stream of dark coffee emerging from the spout.
• Common mistake: The coffee sputtering or flowing too quickly. This indicates heat might be too high or the grind is too coarse.
• How to avoid: If sputtering occurs, reduce the heat slightly.

7. Add Erythritol (Option 1 – During Brew): As the coffee begins to brew, you can add a small amount of erythritol to the upper chamber, just above where the coffee will collect.

• What “good” looks like: Erythritol is visible and ready to mix with the hot coffee.
• Common mistake: Adding too much erythritol at this stage. It’s easier to add more later.
• How to avoid: Start with a small pinch, about 1/2 to 1 teaspoon per serving.

8. Listen for the Gurgle: Once the upper chamber is about two-thirds full, you’ll hear a gurgling sound as the last of the water is forced through.

• What “good” looks like: A gentle gurgling indicates brewing is nearly complete.
• Common mistake: Letting the moka pot continue to brew after the gurgling starts. This can burn the coffee.
• How to avoid: Remove the moka pot from the heat as soon as you hear the gurgle and see light-colored foam.

9. Remove from Heat: Immediately remove the moka pot from the heat source.

• What “good” looks like: The moka pot is safely off the burner.
• Common mistake: Leaving the moka pot on the heat too long. This can over-extract and burn the coffee.
• How to avoid: Be attentive and remove it promptly once brewing is finished.

10. Stir and Sweeten (Option 2 – After Brew): If you didn’t add erythritol during brewing, pour the brewed coffee into your cup. Add erythritol to taste and stir well until dissolved.

• What “good” looks like: The coffee is well-mixed with the erythritol, and there are no undissolved granules.
• Common mistake: Not stirring enough. Erythritol can sometimes clump.
• How to avoid: Stir vigorously for at least 30 seconds to ensure it fully dissolves.

11. Serve Immediately: Cuban coffee is best enjoyed fresh and hot.

• What “good” looks like: A rich, aromatic cup of coffee.
• Common mistake: Letting the coffee sit too long. It can lose its optimal flavor and temperature.
• How to avoid: Enjoy it right after brewing.
