1, Selection of coffee grinding degree
The first step before using a semi-automatic coffee machine to make coffee is to select suitable coffee beans and grind them, which is crucial for extracting delicious coffee. For semi-automatic coffee machines, we need to choose a grinding degree ranging from medium coarse to medium fine, so that coffee beans can fully contact moisture and release more good flavors.
2, Selection of water temperature
A semi-automatic coffee machine is usually equipped with a heating cup, allowing the water temperature to reach a temperature suitable for extracting coffee. The optimal water temperature for extracting coffee is 91-96 degrees Celsius. If the water temperature is too low, the coffee will become bitter, and if the water temperature is too high, the coffee may become too sour and stimulating. Therefore, we need to ensure that the water temperature is just right.
3, The ratio of coffee powder to water
One of the most critical factors in making coffee is the ratio of coffee powder to water. Generally speaking, we recommend using 14 grams of coffee powder to make a cup of coffee, paired with about 30 milliliters of water. However, this is just a starting point, and you can try different proportions based on it to get your favorite flavor.
4, Control of soaking time
Another important factor of a semi-automatic coffee machine is extraction time. During the soaking process, volatile compounds and other aromas in coffee beans will be completely released. For semi-automatic coffee machines, we recommend soaking between 20 and 30 seconds. If the time is too short and the coffee has not been fully extracted, the taste will be relatively weak. If the time is too long, the coffee will become too bitter.
5, Extraction pressure
During the process of making coffee, the extraction pressure can also affect the taste of the coffee. For semi-automatic coffee machines, the optimal pressure is generally between 9 and 10 bar, which can make the coffee extraction more complete and the taste more intense.
In short, the key to making coffee with a semi-automatic coffee machine lies in skills and experience. By gradually trying different factors, we can ultimately adjust the coffee that suits our own taste. But most importantly, with continuous practice and experimentation, you will definitely be able to make beautiful coffee.
