If you drink any type of warm beverage, you must know that first sip feeling: The perfect taste, texture, and temperature. The problem is, that it only lasts for a couple of sips, as warm beverages cool down really fast. For contrast, the optimal temperature for coffee is between 70°C (155°F) - 80°C (175°F). And it only takes about 10 minutes for it to go from 70°C to 45°C at room temperature. Well, that is simply not enough time to enjoy your cup! Think about employees who are attending back-to-back meetings, students who are trying to finish assignments, or even worse, parents who are dealing with their kids.
