Coffee and Its Complex Composition
Coffee, one of the world's most beloved drinks, is a complex beverage with a rich composition. People enjoy coffee for its taste and the pure caffeine it contains. With its popularity, caffeine consumption has become widespread among people. It all starts with the coffee beans, which come from the seeds of a fruit known as the coffee cherry. These beans undergo a series of processes before they are transformed into the aromatic beverage we enjoy.
There are two main types of coffee species: Arabica and Robusta. People consume caffeine in coffee, with varying amounts ranging from 80 mg to 200 mg. Arabica beans, which originate from Ethiopia, are known for their mild and flavorful profile. On the other hand, Robusta beans are more economical to grow due to their resistance to diseases and ability to withstand harsh climates.
The coffee beans are first green and are then roasted at high temperatures to bring out their desirable flavors and aromas. The level of roasting can vary, ranging from light to dark, each producing a distinct taste. Lighter roasts tend to have higher acidity, while darker ones result in a more bitter flavor.
For those who prefer to enjoy the health benefits of coffee without the stimulating effects of caffeine, decaffeinated coffee is a great option. Various methods, including solvent extraction or carbon dioxide gas, are used to remove caffeine from the beans while retaining the other beneficial compounds.
