Title: Coffee Joulies?
Post by: bmac7754 on 02/22/2013 08:51 AM

Just wondering if any coffee drinkers here have tried the Juolie coffee beans.  These were on the show "Shark Tank", and claim when placed in your coffee cup can keep your coffee hot up to 12 hours.  Well I dont take 12 hours to drink coffee but I do like it hot and normal coffee cools down way to fast.  They are about $60 and didnt know if I should waste my dough trying them or if they really work.

 This is their site, if you have not seen them.  http://www.joulies.com

From the March 1, 2013 issue of Cook's Illustrated, and also available on their website, was this article on those:

Freshly brewed coffee can start out too hot to drink—and can too soon end up cold. Enter Coffee Joulies ("JOO-lees"), stainless steel capsules shaped like oversize coffee beans and filled with a proprietary material. The product promises to cool your coffee quickly to the ideal temperature (140 degrees) and keep it there.
 
We bought a set of Joulies for $49.95, which includes five Joulies and a carrying pouch, with instructions to use one "bean" for every 4 ounces of coffee. Then we brewed hot coffee and compared its temperature with and without Joulies in our favorite travel mug and in an ordinary ceramic coffee mug.
 
In the regular coffee mug, results were unremarkable (the temperature immediately dropped to a drinkable 140 degrees with the Joulies but then cooled as fast as the coffee without Joulies). In the travel mug, however, the Joulies made a big difference. The mug with the Joulies rapidly cooled to 140 degrees and held steady for 2 hours. The other mug gradually lost heat, starting out too hot and taking slightly more than 2 hours just to reach 140 degrees. Then both mugs slowly cooled at a constant rate.
 
So how do they work? The "phase change" material encapsulated within each Joulie has a melting temperature of 140 degrees. When it's placed in an environment above its melting temperature, it absorbs heat, cooling the area around it until it is completely liquid. Then it slowly releases heat back into the environment until it becomes solid again. It works just like ice in a drink, which cools the drink to 32 degrees—the melting temperature of water—and then maintains this temperature until all of the ice is gone. Physics aside, the Joulies may work as advertised, but only if you're sipping your brew out of a travel mug—and $49.95 is a lot to spend to address a small woe.

I looked into these after seeing them on Shark Tank.  Found similar research that Jeremy found above.  For your daily mug of coffee these are definitely not worth it.  (And they are large and take up a lot of room in the cup.)  Might be better for a larger thermos when traveling, but then again, if its a good thermos, it will retain the heat anyway.

Now if they could create something like this to keep my humidors at 65 degrees all the time I might be interested!

Sounds like investing in a really good travel mug maybe a better bang for your buck. Here's some links for articles that searches for the 'Best Travel Mug'.

I have to say I tend to spend more money on good coffee than fad's. I do have one of the Thermos Stainless King coffee mugs and it works great at keeping my coffee hot and is durable as hell.

If you fill a humidor half full of kitty litter it will keep its humidity for a long time. But then you need twice as many humidors, or you need to smoke fewer cigars. Sounds like these joo-lees work the same way. Personally, if the coffee is good, I like it at any temperature that doesn't scald my mouth. Coffee slushies are yummy in the summer!

I wouldn't advise putting kitty liter in your coffee, I don't think it would work the same way as the Joulies.

I guzzle my hot coffee way to fast for it to cool down, I like it scalding hot most times. I doubt those beads would be of any use to me.
