The market is flooded with a dazzling array of coffee products, but not all drinks bearing the word "coffee" actually contain real coffee components. Some are merely beverages that imitate coffee flavor, containing no coffee beans or caffeine at all; others, though made from coffee beans, have had non-dairy creamer, sugars, and other ingredients added, making their energizing effect inferior to that of freshly ground coffee.
