Caffeine Introduction Caffeine is an alkaloid. It is found in over 60 plants, such as cola nuts, coffee, tea, and cacao beans. While caffeine is part of the reasons people drink coffee, it plays virtually no role in its flavor.
Caffeine is a white powder which dissolves easily in water and has a slightly bitter taste.
Much of the caffeine that is removed from coffee is sold to pharmaceutical and soft drink companies. By chemicals - The most common chemical used is methylene chloride that clings to the caffeine molecule and is then flushed away. Virtually no traces of the chemical is left. Any chemical that is left behind is evaporated when the beans are roasted. This method produces a better tasting cup of coffee.
