Do coffee Joulies work?
Coffee Joulies work the same way as ice cubes in your drink, but at a higher temperature. Our phase change material was chemically engineered to melt at 60°C (140°F), and with a latent heat of fusion of 220 J/g it is 66% as effective as ice at absorbing thermal energy. This is the best modern science can do, folks.
Are Joulies safe?
Made from the highest grade materials. Joulies are manufactured in a factory that has been making silverware for over a century, so you can be sure it’s done right. Even though it’s completely safe and edible, we’re still obsessive about keeping it inside your Joulies.
Are coffee Joulies reusable?
This works over and over with each cup of coffee poured, creating the perfect sip every time. No need to freeze or recharge Coffee Joulies between cups. Plus, they literally last forever. Includes 5 Coffee Joulies, 1 Glass Mug & 1 Lid.
What are coffee Joulies made of?
Coffee Joulies are small, stainless-steel capsules containing a phase-change material; the capsules were designed to be placed in a cup of coffee in order to cool coffee that is too hot then slowly release the heat to keep the coffee warm.
What is inside Joulies?
If you are not familiar, Joulies are hollow, stainless steel, coffee bean shape capsules which are filled with a phase change material which melts at 140F.
How did Joulies used phase change to solve the problem of keeping the temperature of coffee just right longer than usual?
Coffee Joulies are a unique bean that uses a phase change material, or PCM, to maintain a comfortable drinking temperature. You’re already familiar with one PCM, ice, that is used to keep drinks cold. The ice absorbs heat as it changes to a liquid, keeping your drink cool.

How do you keep coffee warm?
How To Keep Coffee Hot, not warm, without burning it
- Wrap it up with a scarf (or any thick piece of fabric)
- Use a Cup Sleeve.
- Use A Travel Mug (that has good insulation)
- Preheat Your Cup.
- Invest in a Thermos (One that Actually Works)
- Get a Cup Warmer for your Car.
- Use Metal Coffee Beans.
What is the value of specific heat of water?
The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.
What is Joulies shark tank?
Coffee Joulies (pronounced Coffee Jewelies) are stainless steel encased, thermal energy absorbing and reflecting, coffee “beans” that cool your coffee to the perfect drinking temperature and keep it at that temperature for a longer time.
What is Joules on Shark Tank?
The Joulies work by initially absorbing heat rapidly, cooling coffee to drinking temperature (140 degrees). Once 140 degrees has been reached, the Joulies release heat gradually, keeping the coffee at a constant temperature for several hours.
What material keeps coffee hot the longest?
The type of cup that keeps coffee the hottest for the longest is the stainless steel vacuum insulated cups which can keep coffee hot for as much as 6-12 hours. Battery powered heated coffee mugs come in a close second as they can keep coffee at a desired temperature as long as the battery lasts.
How does a coffee Joulie work for coffee?
With Coffee Joulies your coffee will be ready to drink faster and will stay hot longer. 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.
What was the Coffee Joulies before the Shark Tank?
Coffee Joulies Before Shark Tank Dave Petrillo and Dave Jackson, mechanical engineers from New Jersey were the brains behind the development of the Coffee Joulies. The Joulies were small, stainless-steel capsules that contained an ingenious material designed to cool a hot beverage to a drinkable temperature quickly.
How many Coffee Joulies are in a Venti thermos?
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.
