The best water temperature for brewing coffee

Brewing a delicious cup of coffee requires a comprehensive consideration of many factors, among which water temperature is a crucial factor. Properly controlling the water temperature can affect the compounds and flavors extracted from the coffee beans, thus determining whether the final taste is satisfactory. So, what is the best water temperature for brewing coffee? This article will give you a detailed introduction.

1. Understand the coffee extraction process

Before we delve into the topic of proper water temperature, let’s first take a look at the coffee extraction process. When hot water comes into contact with coffee grounds, it dissolves the soluble compounds in them and releases aroma and flavor. This process is called extraction, and it is a key step in adjusting parameters such as taste and strength.

Different compounds are extracted at different rates at different temperatures. For example, at lower temperatures (such as 60°C), there are relatively few bitter components; while at temperatures above 90°C, the bitter component content increases. Therefore, when choosing the appropriate water temperature, we need to comprehensively consider the extraction characteristics of different compounds.

2. Optimal water temperature range

According to expert research and baristas' experience, the optimal water temperature range for brewing coffee is usually between 90°C and 96°C. Within this range, better coffee extraction can be achieved and a good taste balance can be maintained.

If the water temperature is too low, such as below 80°C, some compounds in the coffee cannot be fully dissolved and released, resulting in a weaker taste. If the water temperature is too high, the bitter components are easily over-extracted, affecting the balance of the coffee flavor.

3. Suitable water temperature for different brewing methods

It should be noted that the appropriate water temperature for different brewing methods may also vary. The following are several common brewing methods and their recommended optimal water temperatures:

• Drip: For drip equipment such as filter cups and hand-poured pots, it is recommended to use a slightly higher water temperature between 92°C and 96°C. This can better extract the acidity and aroma of the coffee beans.
• French Press: French Press is suitable for using lower water temperature, generally between 88°C and 92°C. Lower water temperature can reduce the extraction of bitter components and highlight the sweetness of the coffee beans themselves.
• Immersion: Immersion brewing methods such as Turkish coffee and cold brew require water temperatures above 90°C to ensure that the compounds in the coffee powder are fully extracted.

4. Water temperature control method

In order to accurately control the water temperature during the brewing process, the following are some common and effective methods:

• Kettle adjustment: Modern kettles are usually equipped with different gears or have adjustable functions. The required water temperature can be controlled by setting the appropriate gear or adjusting the button.
• Preheat the equipment: Before you start brewing, preheat the filter cup, hand-brewed kettle and other equipment with boiling water. This can prevent the water temperature from dropping too quickly and maintain a more stable brewing temperature.
• Use a thermometer: Use a professional food thermometer to measure the water temperature to make sure it is within the appropriate range.

5. Conclusion

The optimal water temperature for brewing coffee is a key factor that directly affects the taste and flavor of coffee. When choosing the right water temperature, you need to consider the extraction characteristics of different compounds and adjust it according to the specific brewing method. By mastering the correct water temperature control method, you can better enjoy a cup of coffee with a rich taste and rich aroma.
