Can I brew home-ground coffee beans directly with hot water?

Coffee is a must-have drink for many people every morning, and for real coffee lovers, they pay more attention to the coffee making process and taste. Grinding beans to make coffee at home has become a popular trend, but some people don’t know whether they can directly brew self-ground coffee beans with hot water. This article will discuss this issue.

1. Analysis of the principle of Starbucks coffee machine

First we need to understand how brewing coffee works. When we pour water into a substance it comes into contact with, dissolution occurs. When making coffee, we extract the aroma, flavor, and nutrients contained in the coffee beans by bringing water into contact with them in powdered form.

However, after using your own manual or electric machine to grind the fresh coffee beans on site and get them into powder, you cannot brew them immediately. This is because the freshly ground (or just ground) coffee beans contain a lot of carbon dioxide, which needs to be released after a period of time to reach the best brewing state. If you brew directly with hot water, the coffee will taste sour and bland.

2. Coffee beans release carbon dioxide

When coffee beans are processed into powder, the carbon dioxide contained in them begins to be gradually released. This process usually takes several hours or even longer to complete. At this stage, we should not immediately put the freshly ground coffee powder in contact with water.

In order to allow the coffee beans to fully release carbon dioxide and maintain their best flavor and taste, it is recommended to wait for about 30 seconds to 1 minute before proceeding to the next step when making your own hand-brewed or drip coffee.

3. It is recommended to use pre-boiled and slightly cooled water

When making your own pour-over or drip coffee, it is recommended to use pre-boiled and slightly cooled (about 90°C-95°C) water to brew freshly ground coffee beans. This ensures that the water is at the right temperature, not too hot or too cold, which helps to better extract the aroma and taste of the coffee.

In addition, using pre-boiled and slightly cooled water also helps speed up the process of releasing carbon dioxide. When we pour the slightly cooled water into the coffee grounds in contact with it, the carbon dioxide is released faster and more fine and uniform bubbles are produced during the brewing process.

4. It is recommended to wait for a while before tasting

After brewing, it is recommended to wait for a while before tasting the homemade coffee. This is because freshly ground coffee beans need some time to reach the best flavor and taste. Usually, it takes about 2-4 minutes to wait.

During this waiting period, the coffee powder will be fully mixed with the water, and over time, more complex and rich aroma and taste substances will be released during the extraction process. Therefore, it is very important to wait patiently before taking the first taste.

5. Conclusion

Regarding the question of whether self-ground coffee beans can be brewed directly with hot water, we can conclude that it is not recommended to brew freshly ground coffee beans directly with hot water. This is because fresh coffee beans contain a lot of carbon dioxide, which takes a certain amount of time to release to achieve the best flavor and taste. When making your own hand-brewed or drip coffee, it is recommended to wait about 30 seconds to 1 minute before proceeding to the next step, and use pre-boiled and slightly cooled water to brew.

Finally, after brewing is complete, please wait 2-4 minutes before tasting your homemade coffee to fully experience its complex and rich aroma and flavor substances.
