Cold extracted coffee generally refers to a coffee beverage made by grinding coffee beans to a powder at room temperature or lower. Of course cold ice coffee is not necessarily cold extracted coffee, the two concepts are different. Because cold extraction of coffee generally takes longer than traditional hot extraction of substances. This unique temperature and longer contact time gives rise to unique organoleptic and quality characteristics in the finished beverage, characterized by: less bitter taste, smoother taste and finer taste. Cold extraction typically uses water at ambient temperature or colder, thereby extending the time to extract optimal flavor and solids from the beans.
