Coffee only has two problems: either it is too hot or too cold. Who want’s to burn their tongue, right? On the other hand, cold coffee is disgusting. So what to do? Use these engineered cooling beans to keep the perfect coffee temperature. Here is ho it works: each polished stainless steel shell is filled with an advanced phase change material that melts at 140°F. So put them in your coffee and they will absorb heat when it is too hot, storing that energy inside. When your coffee reaches the perfect temperature this stored heat is released to keep it there longer. Brilliant, isn’t it? Now you can have your cake…uhm, coffee, and eat it at the same time.
