Coffee Joulies

Tired of burning your tongue on coffee only to have it get cold a few minutes later? With Coffee JouliesTM your coffee will be ready to drink faster and will stay hot longer.

Each polished stainless steel shell is filled with a special phase change material that melts at 140°F. Put them inside your coffee and they absorb heat when it is too hot and release it back into your coffee to keep it at the perfect temperature.
