Keep Coffee Hotter for Longer

Sometimes it is amazing to see how a simple idea can make such a difference.

If you drink hot beverages you will know that first they are too hot, then just when you think it is the perfect temperature you realise you waited to too long and now it is cold..

Two neighbors – Dave & Dave –  created these cool “coffee beans” called Coffee Joulies …

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.

This amazing feat of thermodynamics happens thanks to a special non-toxic material sealed within the polished stainless steel shell. This material is designed to melt at 140 degrees Fahrenheit, and absorbs a lot of energy as it melts. This is how Joulies cool your coffee down three times faster than normal. Once it reaches this temperature, the special material begins to solidify again, releasing the energy it stored when it melted. This is how Joulies keep your coffee warm twice as long.

How do I use Coffee Joulies?

Pop a few Joulies into your coffee as soon as it’s poured. The hotter the coffee, the more energy Joulies can absorb, and the longer they can keep your coffee the right temperature.

Are Coffee Joulies really safe to put in my coffee?

Yes! Joulies are perfectly safe when used properly, and in fact make drinking coffee safer than usual by reducing the risk of burning your mouth. They sink in your coffee to keep them away from your lips, they won’t ever be hotter than 140°F when used properly (meaning they’ll never burn you), and all the materials used in their construction are food-grade.

How many should I put in my coffee?

Each Joulie is made to work with 5 ounces of volume, so put one in your double espresso, two in your mug, three in your tall coffee, four in your travel thermos, and five in your venti.

What are Coffee Joulies made of?

Joulies are made of the hightest grade stainless steel used in silverware production, ensuring that they are completely safe, will last forever, and will keep their polished finish for a long time.

What’s inside of Coffee Joulies?

Joulies are filled with a proprietary substance called a “Phase Change Material” (PCM) that melts at 140°F and is 100% edible food-grade magic.

How long will my Coffee Joulies last?

Coffee Joulies are made using the same materials and a very similar process as table knives, and will last a lifetime.

Although not yet in production, the Dave’s posted the information on a website called Kickstarter (a place where you can request public funding to start up business ideas) and even though they only needed $9600 funding they were pledged $306944!

No doubt soon we will see this on the market, until then keep sipping that coffee till it is the right temperature…
