Discover the main types of coffee beans and their characteristics

There are many types of coffee beans, but they can be divided into two main categories: Arabica beans and Robusta beans. Arabica beans are the most popular type of coffee beans, accounting for about 60-70% of global coffee production. This bean is grown at higher altitudes and usually presents a more complex flavor profile, including fruity, floral, and sour notes. It has a more delicate taste and is suitable for coffee lovers who like rich layers and delicate flavors.

Unlike Arabica beans, Robusta beans are more cold-resistant and usually grow at lower altitudes. Its coffee taste is stronger and more bitter than Arabica beans, and often has a nutty or woody flavor. Robusta beans contain more caffeine, making it taste stronger. This type of bean is suitable for drinkers who like a strong taste and hope that coffee can provide a stronger refreshing effect.

When choosing coffee beans, understanding the characteristics of these basic types can help you find the coffee that best suits your taste. Arabica beans are generally recommended for delicate single-origin coffees, while Robusta beans are better suited for espresso or blends, providing a thick base for the overall flavor.

How roasting affects the flavor of coffee beans

The degree of roasting of coffee beans directly determines their flavor characteristics. Generally speaking, coffee beans are roasted in three levels: light roasting, medium roasting, and dark roasting. Lightly roasted coffee beans retain more of the flavor characteristics of the original beans, showing a more obvious sour and fruity aroma, suitable for drinkers who like a fresh and bright taste. Coffee beans of this roasting degree usually appear light brown and release less oil during the roasting process.

Medium roasted coffee beans find a balance between sourness and sweetness, with a richer flavor. Beans of this roasting degree show a slightly caramel aroma, and the oil begins to appear on the surface of the beans. Medium roasted coffee beans are suitable for most coffee lovers. It retains the original flavor of the beans and brings the complex flavor added by roasting.

Dark roasted coffee beans are processed at high temperatures for a long time, and the flavor tends to be strong and bitter, often accompanied by caramelized flavors and chocolate-like flavors. Beans of this roasting degree are dark brown or even close to black, and the surface is covered with a layer of oil. Dark roasted coffee is suitable for drinkers who like strong taste and rich flavor, such as espresso and espresso lovers.

Choosing the right roasting degree according to your personal taste can greatly enhance your coffee drinking experience. If you like fruity and sour flavors, light roasting may be the best choice; if you prefer a balanced flavor, medium roasting will meet your needs; and if you pursue a strong and deep taste, dark roasting is undoubtedly the most suitable choice.

Key factors in evaluating coffee bean freshness

Judging the freshness of coffee beans is a key step to ensure the best flavor. First, checking the production date of the coffee beans is the most direct way. Fresh coffee beans are usually marked with a roasting date or a best-drink date. Generally speaking, coffee beans are best flavored within one to two weeks after roasting, so try to choose beans that have been roasted recently.

Secondly, the smell of coffee beans is also an important indicator for assessing freshness. Fresh coffee beans should have a strong aroma, including floral, fruity or nutty aromas. If the smell of coffee beans begins to become bland or has a rancid smell, this is usually a sign that the beans have expired.

The appearance of the beans can also reflect their freshness. Fresh coffee beans have a smooth surface and usually have natural oils. If there are more white mold or discoloration on the surface of the beans, this may be a sign that the beans have been exposed to moisture or improper storage, affecting the flavor of the coffee.

Finally, the storage conditions of coffee beans will also affect their freshness. Storing coffee beans in a sealed container away from light and moisture can help preserve the flavor of the beans. Take out the right amount of coffee beans each time you use them, and try to avoid exposing them to the air for a long time.
