Research carried out in 2015 indicated that more than four hundred (400) billion cups of coffee are consumed worldwide each year. Apart from its great taste, irresistible flavor and extra boost that coffee beverages offer, another main contributor to the high level of coffee consumption is the wide variety of drinks available. The five most popular methods for preparing coffee that you may use to make your favorite beverage are: espresso, drip, brew and filter, plunger method, and the percolator. Coffee beverages are distinguished by their ingredients, preparation time and drink volume. Often times the ingredients used to make many coffee drinks are similar, but those ingredients are used in different proportions. The process of preparing coffee varies in all coffee drinks; however, most beverages are based on the espresso drink. For better clarification, the main differences between the varieties of coffee beverages will be separated into two categories: non-milk based coffee beverages and milk based coffee beverages.
