The perfect cup of joe is determined by a number of things, from the quality of the beans to the roughness of the grind. But even bad coffee tastes best when it is served at an ideal temperature: approximately 58 degrees celsius. But coffee cools quickly, and even the most ideal cup of coffee, exposed to the open air, becomes less than ideal in less than a few seconds.
What’s the java gourmet to do but turn to the sweet aid of technology to help tame that dark but temperate mistress, the coffee cup?
What this means is that if you pour coffee in this cup, the first thing that will happen is that the cup will cool your coffee down to the ideal 58 degrees celsius. Then, when your coffee starts to cool too much, the phase changing material will release the heat back into the cup of coffee.
you can have a perfectly heated cup of coffee without plugging in a warming plate… one that will stay piping hot for up to 30 minutes
