The Most Common Pour Over Mistakes and How to Avoid Them

Die häufigsten Fehler bei der Pour Over Zubereitung und wie man sie vermeidet

Pour-over brewing offers one of the most precise and refined methods for making coffee. However, even with this popular method, mistakes can happen that negatively impact the coffee's taste. In this article, we'll show you the most common mistakes in pour-over brewing and provide helpful tips on how to avoid them to unlock the full aromatic potential of your coffee beans.

Mistake No. 1: Incorrect coffee grind size

The grind size plays a central role in pour-over brewing. A grind size that is too coarse or too fine can significantly affect extraction and lead to an unbalanced taste.

How does grind size affect extraction?

Coffee that is ground too coarsely allows water to flow through the coffee grounds too quickly, leading to under-extraction. The result is a watery and sour coffee. If the coffee is ground too finely, however, the water flows through the filter too slowly, resulting in over-extraction and a bitter taste.

Solution:
Use a medium grind size for most pour-over methods, especially for Hario V60 and Chemex. Adjust the grind size according to personal taste and brewing method.

Mistake No. 2: Incorrect water temperature

Another common mistake is using water that is too hot or too cold. The water temperature has an enormous influence on the extraction of flavors in the coffee.

How does water temperature affect coffee?

Water that is too hot (above 96 °C) can lead to the extraction of too many bitter substances, while water that is too cold (below 85 °C) does not release enough flavors from the coffee beans.

Solution:
Use a thermometer or a kettle with temperature control to ensure the water has an optimal temperature of about 90–96 °C.

Mistake No. 3: Uneven pouring

The way you pour the water over the coffee grounds can strongly influence the taste of the coffee. Uneven pouring often leads to inconsistent extraction, where some areas of the coffee are over-extracted and others are under-extracted.

How to pour water correctly?

A common mistake is to pour the water too quickly and in large quantities over the coffee. This prevents the coffee grounds from being evenly saturated, leading to an uneven brewing process.

Solution:
Pour the water in slow, circular motions, starting from the center outwards. Use a gooseneck kettle to optimize control over the water flow.

Mistake No. 4: Ignoring the blooming phase

The blooming phase is crucial for even extraction, as during this process, the trapped carbon dioxide escapes from the freshly ground coffee. If this phase is skipped or shortened, it can lead to an uneven brewing process.

What is blooming and why is it important?

During blooming, the coffee powder is lightly moistened with water to allow the CO₂ to be released. If this step is skipped, the gases block water absorption, leading to weak extraction.

Solution:
Pour a small amount of water over the coffee grounds and let it "bloom" for about 30 seconds before continuing the rest of the brewing process.

Mistake No. 5: Incorrect coffee-to-water ratio

A common mistake in pour-over brewing is the incorrect ratio of coffee grounds to water. Too much coffee can lead to an overly strong and bitter taste, while too little coffee results in a watery and weak coffee.

How to calculate the ideal coffee-to-water ratio?

A typical ratio for pour-over coffee is about 1:15 to 1:17 – meaning 1 gram of coffee grounds per 15–17 grams of water.

Solution:
Use a digital kitchen scale to precisely measure both the coffee grounds and the water. This ensures that the ratio is always correct.

Mistake No. 6: Insufficient cleaning of equipment

An often-overlooked mistake is insufficient cleaning of pour-over equipment. Residues from old coffee beans or coffee grounds can impair the taste of freshly brewed coffee.

Why is cleaning so important?

Coffee oils and sediments accumulate in filters and coffee pots and can become rancid over time. This affects the taste of the coffee and can even cause health problems.

Solution:
Thoroughly clean your coffee filters and pots after each use. Use special cleaning agents or dish soap to ensure no residues remain.

Conclusion: Avoid mistakes in pour-over brewing and enjoy the perfect coffee

Pour-over brewing requires precision and attention to detail. By avoiding the most common mistakes – whether it's with water temperature, grind size, or proper pouring – you can experience the full coffee enjoyment. With the right techniques and a little practice, every cup of pour-over coffee becomes an unforgettable experience.
