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. Price: $49.95
This works thanks to a special material sealed inside the polished stainless steel shell called a “phase change material” that is able to absorb a large amount of energy as it melts at a specific temperature. We use a PCM that melts at 140 degrees Fahrenheit, which have found to be the perfect temperature for drinking any hot beverage including coffee, tea and hot chocolate. This material is food-based and completely nontoxic.
Each Coffee Joulie works with 4 ounces of hot beverage, so toss one in your espresso, two in your double-short vanilla latte, three in your tall drip, four in your vacuum thermos and five in your venti or xl coffee right when it’s poured. The material sealed inside the Joulie will begin to melt, absorbing energy from your coffee and cooling it down to the right temperature, 140 degrees Fahrenheit, three times faster.
When your coffee reaches this temperature the process reverses. The phase change material begins solidifying, releasing the energy it stored earlier back into your coffee, keeping it hot twice as long. When used in a high-quality vacuum thermos, Coffee Joulies can keep your coffee in the right temperature range for over five hours!
