Coffee Joulies are small coffee bean temperature regulators made from stainless steel. These little bean were a successful featured product on the popular TV show Shark Tank. You might be wondering how do Coffee Joulies work? Essentially, each stainless steel bean has a different specific heat value from whatever drink that they are in. Because this value is different, some the heat is transferred over from the drink to the bean. Not only does this balances out the temperature, but it also holds that comfortable temperature for a significantly long time. Thus, providing the optimal beverage temperature.
Each bean displaces about 1.5 tablespoons of your beverage, which is roughly 15% of the average coffee cup. Coffee Joulies was originally a Kickstarter company that was funded. Now it has evolved to a successful, full company. Before investing in this product, be sure to read the Coffee Joulies Shark Tank/user reviews to make sure that this is a drink temperature regulator that will completely meet your expectations

They look great.They’re also much larger than I expected, although that’s not a bad thing.
These feel like extremely high-quality items, and they also don’t impart any metallic taste that I can detect. They seem very well-made.
Sounds good. Let’s see how well it works.
This is a very clever idea. The physics is sound, but there is something wrong with the implementation and it’s grossly overpriced
It’s an elegant principle. Sadly, it doesn’t work in practice. Well, the physics works, of course, but the effect is so small that is it not worth the price or the inconvenience of having a bunch of noisy little rocks in my thermos.
These DO NOT WORK. I used it in my insulated travel mug, and although it does cool the coffee quickly, in my heated car was unpalatably cool in 40 minutes. I tried pre-heating the mug with hot water, which seemed to help, until I discovered that the coffee stayed just as hot with the mug preheated WITHOUTH the joulies. Plus, they take up almost half the space in the mug and make it heavy. Very disappointed. I would not feel so bad had I not wasted so much money on these!
