Coffee is a drink made from roasted coffee beans that contains caffeine and helps wake people up in the morning. The quality of coffee depends on factors like where the beans are grown, stored, and roasted. Coffee originated in Italy but spread throughout the Arab world and is now consumed in almost every country, making it an important commodity for both producers and consumers. Coffee provides vitamins and caffeine that can stimulate metabolism and increase adrenaline, muscle tension, and contraction capacity.
