The quality of a cup of coffee can be largely determined by the coffee beans you choose, especially when you brew a cup of coffee at home. The choice of coffee beans becomes crucial. Do you know what kind of coffee beans can make a fragrant cup of coffee? How should you choose coffee beans? Let's learn together.

How to choose coffee beans

Faced with the dazzling array of coffee beans on the shelves, how should we judge the quality?

1. Judgment of appearance

Delicious coffee can be judged from the shape of the roasted coffee beans. Of course, bad coffee beans cannot be mixed in. What is more important is that normal beans can also be mixed into high-quality coffee beans and cause problems. The roasted beans that brew delicious coffee must first be large and plump, and uniform. Secondly, they must be of the same size and without color spots. These are the key points of visual judgment. If you look carefully, it should not be difficult to distinguish.

2. Judgment during grinding

Delicious coffee can only be brewed after the coffee beans are fully roasted and the moisture is extracted. This can be judged when grinding the coffee beans. Good quality coffee beans will make a slight rustling sound when grinding, and the original flavor of coffee will overflow when the hand is gently shaken. Poor quality coffee beans will make a creaking sound and feel stuck when grinding.

3. Judgment during extraction

The simplest way to brew delicious coffee is to filter and extract it with filter paper. When brewing and extracting, there is also a way to judge whether the coffee is delicious, that is, whether the powder swells up when added to hot water. When the coffee is fully roasted and the water is extracted, there will be beautiful and delicate foam swelling up when brewing.

4. Judgment after extraction

Although the concentration of coffee may change due to different roasting and extraction methods, the characteristic of delicious coffee is that the coffee liquid extracted under the same conditions is clear, and the spoon can be clearly seen through the extract. It is difficult to distinguish a single cup, but if you compare it, you can tell at a glance whether the coffee is delicious. A cup of delicious coffee will still be clear in color and taste even after 30 minutes.

5. Judging by the taste and aroma of coffee

The acidity of gourmet coffee is refreshing like citrus fruits, without strong acidity. The bitterness is soft and not bitter like smoke or burnt taste.
