Liberian coffee beans-Liberian coffee is recognized as the third largest coffee variety in the coffee trade. It is also grown at low elevations. Grown in Africa and exported only to Europe, this coffee is also a cheap coffee, very similar to Robusta, which comes from a high-yield and disease-resistant variety and is more resistant to large temperature differences than small coffee beans. It is best grown at lower elevations. Medium-sized coffee beans, just like its English name "Robusta," have a strong taste and texture, with a bitter taste, and are not too acidic, giving strength and concentration to coffee. This coffee contains 2% caffeine and produces more beans than Arabica coffee, which can produce 2-3 pounds of coffee per year. This coffee is often treated as a low-end coffee on the market. Robusta coffee is widely used to make instant coffee and blends, as well as iced coffee and canned coffee. Arabica-Arabica beans grow best at altitudes of 3,000 to 6,500 feet (600-2,000 m) in temperate and subtropical environments, which allows it to grow longer and thus make its coffee taste more intense. Coffee beans are oval and flat. Arabica coffee contains more elegant flavor, delicate taste, fragrant smell, high acidity, smooth texture, bring aroma and smoothness to coffee. Its caffeine content is around 1%. Because of its delicate growing environment, each coffee tree produces only 1-1.5 pounds of coffee per year. Many coffee enthusiasts and professional producers like to choose this coffee. Arabica coffee accounts for 75% of global production. Due to its susceptibility to pests, frost and drought, Arabica coffee trees require a very delicate environment to grow, especially at present, coffee plants grown in different regions of the world mainly include the following species: ARABICA/ROBUSTA/LIBERICA/DEWEVREI/STENOPHILLA/CONGENSIS/ABEOKUTAS/KLAINII/ZAANGUEBARIAE/RACEMOSA.
