Coffee beans are seeds belonging to the Rubiaceae family, under which there are at least 25 main varieties of Coffee Genus, of which the two most important varieties are Arabica species Coffee arabica (Arabica coffee) and Canafora species Coffee canephora (Robusta coffee), also known as Robusta coffee. Arabica coffee beans account for 70% of global production, and robusta coffee beans account for about 30%. Arabica coffee has 44 chromosomes, while robusta coffee has 22 chromosomes, so Arabica coffee is a crop that cannot be crossed with robusta coffee.

Coffee trees are affected by climate, altitude, soil quality and other factors in different regions, which affect the quality and flavor of coffee beans, just like other agricultural products such as tea and wine. Therefore, even if they come from the same country, different regions have different flavors, and the prices naturally vary. Coffee trees belong to evergreen plants, cultivated in tropical and subtropical areas, the most suitable growth conditions are, to have a proper amount of rain, soil drainage is good, so more choose in rich volcanic ash (rich in organic matter) inclined slope, and therefore most of the high-quality Arabica coffee beans are manually harvested and then carried down by horses or mules. Climate has a big impact on coffee prices. Brazil, the world's largest coffee producer, suffered two severe frosts in 1994, causing the price of coffee beans to skyrocket from about US $1000 per metric ton to about US $2400. It also attracted coffee merchants to Vietnam to grow coffee. Coffee bean prices collapsed under uncontrolled cultivation, dropping to as little as $500-$600 per metric ton in 2001 and 2002. In 2002, approximately 1 million coffee-related farmers in Central and South America were unemployed and countless families were in distress. Ethics in your Coffee Cup
