The main types of coffee beans and their characteristics

There are four main types of coffee beans: Arabica, Robusta, Liberica and Excelsa. Each type of coffee bean has its own unique flavor and growing conditions.

Arabica coffee beans are the most popular variety, accounting for about 60% to 70% of global coffee production. It is mainly grown in higher altitude areas, such as the mountains of Latin America. Arabica beans are known for their higher acidity and rich flavor, often with floral and fruity characteristics.

Robusta coffee beans are characterized by their higher caffeine content and bitter taste. This variety of coffee is mainly grown in low-altitude tropical areas such as Africa and Southeast Asia. Robusta coffee beans are pest-resistant and have high yields, and are often used in instant coffee and blended coffee.

Liberica and Excelsa coffee beans are relatively rare. The former is mainly distributed in West Africa and has unique floral and fruity aromas. The latter is a variant of Liberica, mainly grown in the Philippines, and sometimes has smoky or woody characteristics in taste.

Characteristics and market of Liberica and Excelsa coffee beans

Although Liberica and Excelsa coffee beans have a smaller market share, they each have unique flavor characteristics. Liberica coffee beans are mainly produced in West Africa, especially Liberia, and their flavor often has a unique floral and fruity aroma, and may have some woody or smoky layers in the taste. Due to its relative rarity, Liberica beans are not as popular as Arabica or Robusta in the global market.

Excelsa coffee beans are actually a variant of Liberica beans, mainly found in the Philippines. Its flavor is similar to Liberica, but often has a more pronounced fruity and nutty aroma. The uniqueness of Excelsa beans lies in its ability to grow in the special climatic conditions of the Philippines, showing flavor characteristics that are different from other coffee bean varieties.

These two beans occupy a smaller share of the coffee market, mainly due to their low production and relatively limited market demand. However, their unique flavors have earned these beans a certain following in the specialty coffee community. Due to their rarity and unique flavor experience, Liberica and Excelsa beans are often used in high-end coffee tastings and innovative beverages.

How to choose the right coffee beans for your taste

Choosing the right coffee beans should first be based on personal taste preferences. Arabica beans are suitable for coffee lovers who like complex flavors and higher acidity. If you like fresh and fruity coffee, Arabica beans are a good choice. On the other hand, if you prefer a stronger and full-flavored coffee, Robusta beans can provide a stronger refreshing effect due to its strong bitterness and higher caffeine content.

In addition to taste, the acidity of coffee beans is also an important selection factor. Arabica beans generally have higher acidity, which can give coffee a unique fruity and floral aroma, while Robusta beans have lower acidity and focus more on bitterness and richness. If you are sensitive to acidity, you may prefer low-acid Robusta or blended beans.

Caffeine content is also an important consideration when choosing coffee beans. Robusta beans contain more caffeine than Arabica beans, thus providing a stronger pick-me-up. If you need an extra boost of energy in the morning or at work, Robusta beans may be better for you.

Finally, the origin and roasting degree of different coffee beans will also affect the final flavor experience. Arabica beans grown at high altitudes may present a more complex flavor, while beans grown at low altitudes are usually more straightforward in flavor. Knowing this information can help you choose the coffee beans that best suit your taste and needs.
