Coffee Joulies Endo-Exothermic Phase Change Gold Coffee Beans - Cool Your Coffee


There's a project over a Kickstarter (a new way to fund creative projects) called Coffee Joulies which Single Serve Coffee and other coffee lovers have decided to sponsor (and so can you if you want some 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.

How do they do this? There is a special non-toxic material sealed within the polished stainless steel coffee bean 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.

We're ready to cool down some of the piping hot coffee we consume, and also to keep our single serve coffee warm longer. We'll be getting 5 of these Coffee Joulies packs, so if you think you're deserving - sound off in the comments and we'll be doing a random drawing from the best comments and send the Coffee Joulies to the lucky commenters later this Summer.

I need these! The coffee pot at work pretty much scalds the skin off the roof of my mouth. Would love to get some Joulies!!!

I can't wait to get some of these! I have sensitive teeth and putting ice in your coffee just waters t down and I like my coffee very strong. Thank you for coming up with these!!

How awesome! I hate when I burn my tongue, only to wait too long for my coffee to cool down and then have cold coffee. What a cool idea!

Interesting, but I don't see them going beyond a specialty gift market.

Good golly Miss Molly, I gotta get me some of these Jouiles!

I can't wait to be able to drink a whole cup of joe before it gets too cold. If these work they will be worth their weight in gold.

I'd love to try the Joulies out - I'm a scientist so any cool gadget that relies on science to supply the "wow" factor gets my attention!

Oh coffee gods you have heard the cry of the new mother and answered. I often times go to make a cup of coffee and find it a bit too hot and by the time it gets to the right temperature my beautiful little baby girl needs me. So after changing a diaper, nursing her, or just playing some peek-a-boo my coffee is now too cool. I haven't been able to enjoy a decent cup at the right temperature since she came home. And believe me, new mommy's need their coffee. These Joulies would allow this mommy to get her coffee fix and still be the best mommy ever. :)

Amazing idea. I generally pour only small portions of coffee at a time, so the thermal mass of my mug brings the temperature down to "drinkable" range quickly. Unfortunately, with just a small amount of coffee, it gets cold quickly unless I drink it right away. With these Joulies, I can pour a whole cup, have it cool down quickly so I can drink it and still enjoy the whole cup.

I've just bought a new travel mug that keeps my coffee too hot! Even after a few hours the buggers still tongue burning hot, I found out the hard way!! I operate a subway train so being distracted is not a good thing, but I really like and need my coffee. The bonus is the wow factor of showing my Joules off and explaining how they work while waiting for my train and on my coffee break.

Great idea! I'd really enjoy testing this to see how well it works.

My husband is always saying his coffee is too hot, so these would be PERFECT for him. Plus I could blog about them... ;)

Posted by: Marla at April 1, 2011 7:47 AM

I'd love to try some!

As a scientist - I am enthralled and intrigued by the Joulies. Must. Try. Out.

These joulies beans sound like a perfect solution for my Keurig. I find that the coffee is a bit too hot as it comes out of the machine, so I have to wait a bit for it to cool before I can enjoy. I also find that I get more flavor once it cools a bit. Even though these should help keep the cup hot longer, all I can say is "cool beans!"

I'm sweet and shy by nature but when it comes to drinking HOT coffee I break all of Emily Post's rules and SLURP my java like a burly old farmhand. I NEED these Joulies so I can sip my coffee properly like the pearl-wearing girl I am!

It wouldn't actually start to solidify again until the coffee dropped below the melting point of the Joulie bean (great name, by the way, should be a favorite of physical chemists.) The problem is that unless you make your coffee too hot on purpose there is no extra energy to store so they would initially just cool your coffee too much. (The only way to get the heat to add later is to add too much heat to your coffee in the first place.)

I think these would be awesome. I often find my coffee too hot right off the hop but once it starts to cool it gets too cool quickly.

Posted by: GmanJenks at March 31, 2011 9:21 AM

Ooh, I can already hear myself saying, "I got my Joulies from single-serve coffee. How did *you* get *your* Joulies?" Sorry, just had to go there. ;) Seriously, though, what is this "too-hot coffee" problem you speak of?
