There’s more to a perfect cup of coffee than selecting the right blend to brew: no one’s going to be able to enjoy it with their taste buds burnt off. That’s where Coffee Joulies come in. Thanks to a special non-toxic material that’s sealed inside the Joulies’ bean-like stainless steel shells, these wondrous creations help to cool down your drink to approachable levels faster than normal, then use the energy stored during that process to keep it warm.
