As I come from Melbourne, the city of coffee snobs, I would probably never have a use for these Coffee Joulies. But I think these guys are really sweet and may be onto something here. So what is is? Well, ‘Coffee Joulies work with your coffee to achieve two goals.
First, they absorb extra thermal energy in your coffee when it’s served too hot, cooling it down to a drinkable temperature three times faster than normal. Next, they release that stored energy back into your coffee keeping it in the right temperature range twice as long’. For those of you burning your tongues on too hot lattes or having to pour out the second half of a luke-warm to freezing mocha, get on board!
