About Coffee Joulies

Based out of Sherrill, NY, Coffee Joulies are engineered, polished, stainless steel coffee beans filled that soak up the excess heat in your coffee, and make the temperature “just right” in a matter of minutes. Coffee Joulies were originally featured on episode 13 of season 4 of the popular ABC television show Shark Tank, where four of the “sharks” ended up partnering with the company.

Coffee Joulies holds an F rating with the Better Business Bureau, which is based on two unresolved complaints within three years. Overall, customer satisfaction appears to be fairly low for the product, with the most common complaint citing that they did not work anywhere near as well as claimed.

How Coffee Joulies Works

At their most basic, Coffee Joulies are 18/10 stainless steel “shells” filled with a unique phase change material (PCM), which becomes a solid at less than 140°F, and a liquid at 140°F or higher. As a result, when you add the Joulies to your coffee, the material contained inside melts, absorbs the heat, and quickly brings down the temperature to a more comfortable level. Then, when the temperature of your coffee dips below 140°F, the Joulies re-solidify and release all their stored heat back into your coffee.

Each Coffee Joulie is about half the size of a medium egg, and is claimed to keep your coffee warmer, for twice as long. All stainless steel used in the product comes from 85% recycled material, and the PCM contained inside is “a special blend of extremely pure plant-derived materials that are already used as ingredients in food.” In addition, all Coffee Joulies are made in the USA, and are claimed to be extensively tested prior to leaving the factory, including the use of a helium leak tester.

For a complete run-down of the process, full instructions can be found here.

Bottom Line: Are Coffee Joulies a Scam?

So, with all this information at hand, what’s the bottom line: Are Coffee Joulies a scam? Based on our research, the company appears to manufacture a well-thought out product, with an intense focus on quality craftsmanship. In other words, Coffee Joulies appear to feature high quality materials wrapped in an attractive, well-designed package.

However, based on the wide variety of online reviews we referenced during our research, quality only gets the product so far. This is because the number one complaint we found was failure to work as advertised; in other words, when it came down to it, there wasn’t much of a difference between using Coffee Joulies, and not using them. In fact, this blog featured an early review of the product, and unfortunately the Coffee Joulies didn’t perform very well. Granted, this was a very informal test and didn’t take into account many of the variables that could affect performance, but it was fairly revealing nonetheless.

With this in mind, if you plan on purchasing a set of Coffee Joulies, keep in mind that you may be paying more for the artistic design than for something that works as well as it claims.

    Love my Coffee Joulies

    • Glendale, CA,
    • Oct 29, 2016

    I got the Coffee Joulies and thermos as a gift after the Kickstarter and it is THE BEST. When used properly it will keep my coffee hot for hours. I preheat the thermos and Joulies with hot water, pour in my coffee and head out. I've left my coffee in the car all day, gone back out to my car to find my coffee is still hot. I would highly recommend.

    Bottom Line: Yes, I would recommend this to a friend

    Do not work as advertised

    • Augusta ME,
    • Jan 13, 2016

    Bought these to keep my coffee warm in my ceramic mug. Put Joulies in one cup not the other. Both cooled but Joulies did not keep coffee warm any better than the other one. Returned, no refund in 3 weeks. Got sucked into their slick webpage.

    Bottom Line: No, I would not recommend this to a friend

    Product does not work

    • Roswell, NM,
    • Jul 15, 2015

    Product does not work. Very dissatisfied. Not only do you still have to warm your coffee, but now you have to take the darn Joulies out to do so. What a scam.

    Bottom Line: No, I would not recommend this to a friend

    Never received

    I ordered the Coffee Joulies on 06/13/2015 and was charged for them on 06/15/2015. I have received as much as a confirmation email about my order. I have emailed customer service twice and have not heard back from them. My next step will be getting the BBB involved, they should at least give me my money back. What a crappy company that they can't even acknowledge my order or emails. Until this is resolved by either getting the product or getting refunded I can not recommend this to anyone.

    Bottom Line: No, I would not recommend this to a friend
