Does drip coffee have to be brewed with hot water?

Drip coffee is a convenient and quick way to make coffee. It does not require a coffee machine or filter paper. You only need to put the bagged coffee into a cup and pour in hot water. However, some people believe that drip coffee must be brewed with hot water to achieve its best effect. This article will explore this issue from several aspects.

1. The production principle of drip coffee

To understand whether hot water must be used to brew drip coffee, you first need to understand its production principle. Drip coffee is usually packed in a filter bag with powder. After adding hot water, the solutes (such as aroma, coloring substances, etc.) are dissolved into the liquid phase through soaking and stirring, and the solid particles are kept separated from the liquid phase through the filter bag.

2. Theoretically, water of other temperatures can be used

Although we are traditionally used to brew coffee with hot water that has been cooled slightly from boiling to around 90°C, in theory, water at other temperatures can also be used for brewing drip coffee. The dissolution rate and equilibrium concentration of solutes may be different at different temperatures, which may affect the taste and aroma of the coffee.

3. The effect of hot water on the taste and aroma of drip coffee

In fact, using hot water to brew drip coffee can usually better extract the flavor substances in it. At a higher temperature, the aroma substances are more easily released and the acidic components are more easily extracted. This makes brewing with hot water produce a richer, mellower and more layered taste.

4. Effect of temperature on caffeine content and bitterness

On the other hand, brewing drip coffee at a higher temperature may result in more caffeine and increased bitterness. If you like strong and bitter coffee, brewing with hot water may be more suitable for you. But if you are sensitive to caffeine or like a softer coffee, you can try brewing with slightly lower temperature water.

5. The influence of personal taste preferences

Ultimately, whether or not you must use hot water to brew drip coffee comes down to personal taste preference. Some people like a strong and mellow taste, so they may choose to brew it with hot water that has cooled slightly from boiling to around 90°C. Others prefer a lighter, softer taste, so they can try brewing with water at a slightly lower temperature.

in conclusion

In short, there is no strict rule that drip coffee must be made with hot water. According to personal needs and preferences, you can choose water at different temperatures to achieve different taste effects. Whether you use high or low temperature water to make drip coffee, you need to pay attention to corresponding measures in ensuring hygiene, safety and quality.
