Most common mistakes when preparing coffee (and how to avoid them)

Summary: Making coffee seems simple, but small details can make all the difference. Here are the most common mistakes and how to avoid them to achieve a perfect cup.

1. Using old or poorly preserved coffee

Coffee loses aroma and flavor over time. Store it in an airtight container, away from sunlight and moisture.

2. Unfiltered tap water

98% of your cup is water. Use filtered or mineral water to avoid chlorine and minerals that distort the taste.

3. Measure “by eye”

Use a scale: the ideal ratio is 1:16 (1 gram of coffee to 16 grams of water).

4. Incorrect grinding

A very fine grind produces bitterness; a very coarse grind produces a lack of flavor. Adjust according to the method.

5. Lack of cleanliness

Rancid oils from old coffee alter the flavor. Clean your equipment regularly and rinse with hot water.
