what is coffee

Coffee is a beverage that is prepared from roasted coffee beans. The coffee plant belongs to the genus Coffea, and there are over 500 genera and 6,000 species of tropical trees and shrubs within this genus. Coffee trees grow best in rich soil, with mild temperatures, frequent rain, and shaded sun, and they are typically grown in a region of the world called the Coffee Belt. The two most important coffee species in the commercial coffee industry are Arabica and Robusta. Coffee is one of the three most popular beverages in the world, alongside water and tea, and it is one of the most profitable international commodities. The popularity of coffee is mainly attributed to its invigorating effect, which is produced by caffeine, an alkaloid present in coffee. Coffee is often consumed alongside breakfast or as a dessert beverage, and it is served in coffeehouses and restaurants worldwide. Coffee beans are roasted to turn them into the fragrant, dark brown beans that are used to make coffee, and the roasting process creates flavors and turns the green beans brown.
