This should be a common problem for all coffee drinkers anyone who enjoys a hot beverage. It’s too hot at first and burns your tongue. Then, before you know it, it’s cooled to become a tasteless & cold brew. There are people in this world who will not accept this fact and will actively strive to battle against the norm. I introduce Dave Petrillo and Dave Jackson. They are both engineers that were faced with this serious problem that plagued the world’s coffee drinkers and they have found a perfect solution: Joulies! [pronounced: Joo-Lees]


With a Joulie your coffee will be ready to drink in minutes and will stay that way for hours. Each polished stainless steel shell is filled with a special phase change material that melts at 60°C. Put them inside your coffee cup and they will absorb heat from your coffee when it is too hot and release it back into your coffee to keep it at the perfect temperature. And the best part? They will last forever.

You can use them for anything. They will work with tea, hot chocolate, soup,…the list goes on. They are currently available to purchase via the Jolies website at for $89.95 for a set of 5 stainless steel shells. If you don’t like them, you can send them back for a full refund. I doubt they will cover the shipping fees back to America, so the only other solution I can think of would be to give them to us.
