Do coffee Joulies work?
Coffee Joulies work the same way as ice cubes in your drink, but at a higher temperature. Our phase change material was chemically engineered to melt at 60°C (140°F), and with a latent heat of fusion of 220 J/g it is 66% as effective as ice at absorbing thermal energy. This is the best modern science can do, folks.

How did Joulies used phase change to solve the problem of keeping the temperature of coffee just right longer than usual?
Coffee Joulies are a unique bean that uses a phase change material, or PCM, to maintain a comfortable drinking temperature. You’re already familiar with one PCM, ice, that is used to keep drinks cold. The ice absorbs heat as it changes to a liquid, keeping your drink cool.
