The correct brewing temperature for filter coffee

Die richtige Brühtemperatur für Filterkaffee

Coffee Brewing Temperature:
For the perfect coffee preparation, the water temperature during brewing should be between 86 and 92 degrees Celsius. When the coffee comes out of the machine, a temperature of about 85 degrees Celsius is ideal. The cup in which the coffee is served should have a temperature of approximately 67 degrees Celsius.

Espresso Brewing Temperature:
With high-quality portafilter machines, the brewing temperature can be adjusted. It is suggested to brew espresso at a temperature of 93.0 degrees Celsius. For very light roasts, it is advisable to increase the brewing temperature by 1-2 degrees, while for darker roasts, a reduction of 1-2 degrees is recommended.

Filter coffee is making a real comeback. But not only the right grind, but also the perfect brewing temperature determines whether the coffee is flavorful or not.

Filter methods (pour-over, filter machines, Bodum pot, Karlsbad pot, etc.) require 92-96°C. For espresso machines (semi-automatic and automatic), the optimal temperature is between 88-94°C (depending on the coffee variety!). You should remove a Moka pot (Bialetti, Alessi, or similar) from the stove as soon as the coffee is ready and not let it continue to boil on the burner. If the brewing temperature is lower, many of the over 1000 different aromas cannot fully develop and the coffee tastes too light. If the water is still boiling, many aromatic substances burn and the coffee becomes too strong and bitter.

For most filter coffee varieties, the ideal brewing temperature is between 92°C and 96°C depending on the preparation method. Within this temperature range, the flavor facets are optimally extracted and the coffee unfolds its full potential.

Why is brewing temperature so important?

The temperature at which coffee is brewed significantly influences its taste and aroma. Water that is too hot can burn the coffee and leave a bitter taste. Water that is too cool, on the other hand, does not separate all the flavor notes from the coffee grounds. Therefore, finding the right balance is of utmost importance.

The Science Behind It

When brewing filter coffee, temperature plays a crucial role. The right brewing temperature allows the valuable flavor notes and aromatic compounds to be extracted from the bean and presented in the cup of coffee. It is interesting to note that not only the preparation method but also the equipment used, e.g., filter coffee machines or the portafilter for espresso, can influence the optimal temperature.

The general consensus for brewing filter coffee is a water temperature between 88 and 96 degrees Celsius. This temperature range is ideal for most roasts. Temperatures that are too high, e.g., above 96 degrees, can cause the coffee to be over-extracted, resulting in a bitter taste. Temperatures that are too low, below 88 degrees, can make the coffee watery and flat, as not enough aromatic compounds are extracted from the coffee.

Filter paper and the amount of water used also influence the preparation. In general, it is recommended to use about 200 ml of water per cup. When preparing filter coffee, care should be taken to pour the water evenly over the coffee powder. This ensures that the aromas are evenly separated from the ground bean and released into the brewed coffee.

It is also important to note that different roasts have different flavor profiles. Darker roasts tend to have less acidity, while lighter roasts often have higher acidity in the coffee. When brewing, it is therefore important to ensure that the temperature complements the character of the roast and does not overshadow the coffee.

Preparing Filter Coffee: An Art in Itself

Preparing filter coffee is not just about making coffee. It's about extracting all the coffee's aromas without releasing unwanted bitter substances. Whether with a pour-over filter or a filter coffee machine, the key to aromatic filter coffee lies in the combination of grind size, amount of coffee, and the right water temperature.

Grind Size and Coffee Amount

For an aromatic coffee, it is essential to grind the coffee correctly. Too coarsely ground coffee leads to a watery result, while too finely ground coffee can taste bitter. A guideline is approx. 60 g of coffee per liter of water. The ratio of coffee to water can be adjusted according to preference.

The Perfect Brewing Temperature

The ideal infusion temperature is between 88°C and 96°C. Water with a temperature in this range separates the desired aromatic compounds without dissolving bitter substances. A thermometer can help to precisely control the temperature. If no thermometer is at hand, let the water cool for about a minute after boiling.

Preparation with a Pour-Over Filter

Coffee preparation with a pour-over filter is timeless and allows full control over the brewing process. The coffee powder is placed in the pour-over filter, which is equipped with a paper filter or metal sieve.

Pour the water slowly in circular motions over the coffee grounds, so that the water level in the filter remains constantly balanced. This allows for even extraction and ensures that the coffee can unfold its full bouquet.

Tips and Tricks for the Perfect Filter Coffee

  • Use freshly roasted and ground coffee beans for the optimal aroma.
  • Pay attention to the freshness of the water. Always use fresh, cold water for boiling.
  • Experiment with the grind size. Is the coffee too bitter? Grind it a little coarser next time.
  • Avoid boiling water. High temperatures can burn the coffee and affect the taste.
  • Pay attention to the contact time. The longer the water is in contact with the coffee, the more aromas are extracted. However, too long a contact time can lead to over-extraction and a bitter taste.

Tips for Controlling Water Temperature

  • Use a thermometer: A precise kitchen thermometer can help you accurately monitor the temperature of your water.
  • Preheat: Pour hot water into your coffee pot or filter before brewing the coffee. This helps minimize temperature fluctuations.
  • Use fresh, cold water: Always start with fresh, cold water and heat it to the desired temperature.

The Impact of Brewing Time

In addition to temperature, brewing time also plays a crucial role. For filter coffee, we recommend a brewing time of 3 to 5 minutes. Too short a brewing time leads to weak coffee, while too long a brewing time can make the coffee bitter.

Choosing the Right Coffee Grounds

The grind size of the coffee grounds also affects the brewing result. A fine grind can slow down the water flow and lead to over-extraction. A coarse grind, on the other hand, can lead to under-extraction. For filter coffee, a medium grind is ideal.

Possible Errors and Their Effects

Coffee is not just a drink, but an art. When preparing filter coffee, however, errors can occur, especially if the infusion temperature is not optimal. Filter coffee machines and other preparation methods often offer precise temperature control, but deviations can still occur.

If the coffee is brewed too hot, for example, above 94 degrees, it can taste bitter. Too high temperatures can damage the fine aromas in the ground coffee and highlight unpleasant flavor notes.

On the other hand, if the coffee is brewed too cold, it can taste flat and under-extracted. This means that not all desirable flavor compounds are extracted from the coffee. Such an error in filter coffee preparation can result in the coffee being less full-bodied and aromatic.

When preparing coffee, it is therefore important to pay attention to the taste. If the coffee tastes too bitter or too sour, this could be an indication of too high a water temperature. If, on the other hand, it tastes too thin or watery, it was probably brewed at too low a temperature.

Properly preparing filter coffee makes the coffee a true delight. It is therefore worthwhile to take your time and carefully monitor the brewing temperature to achieve the perfect coffee experience.

Conclusion

Preparing filter coffee may seem simple, but it requires attention and precision. Whether you brew your coffee with a manual filter or a filter coffee machine, the right brewing temperature and grind size are crucial for delicious coffee enjoyment. Take the time to perfect your coffee and savor every sip!
