Coffee Joulies


If you’re a coffee drinker and you’re as busy as I am I’m sure you’ve had many days where your coffee is cold by the time you get a chance to sit down and have a sip. I’ve tried multiple insulated travel mugs and they help, but sometimes that still isn’t enough.

Enter Coffee Joulies.

These little guys have been scientifically engineered to make coffee drinking a better experience, and as a little bit a nerd that is one of the biggest reasons I love them!

The Product

So now the all important question, what are Coffee Joulies?

Coffee Joulies are big stainless-steel encased coffee beans you put in your coffee when you pour your cup. They initially cool your coffee to a drinkable temperature in minutes (literally) and then keep it warm much longer than normal.
Tootsie Pop for scale!

Now my fellow nerds are wondering, ‘How does it work?’ Well let me tell you.

So, each Joulie contains something called phase change material. This material absorbs the heat from the coffee and then uses it to keep the temperature perfect for drinking by slowly releasing the heat back into your cup. This phase change material is non-toxic and edible, so it is safe to use in your cup ‘o Joe.

They’re shaped like coffee beans, but they can be used in any hot beverage. Even soup!

Use and Care

The creators of Coffee Joulies recommend one Joulie for every 4 ounces of coffee for maximum effectiveness.

Coffee Joulies are not dishwasher safe, but they are still easy to clean. Just a little hot soapy water after use and they’re good to go for next time!


My Thoughts

I love them!

I had some serious doubts about them when I opened the box. I mean, come on. Giant coffee beans that are somehow going to improve my coffee drinking experience. I was pretty happy with my current insulated travel mug and couldn’t really see how they could be any better.

Despite my doubts I couldn’t wait to try them.

So, the next day, literally, I got my coffee ready like usual but I put three Joulies into my insulated travel mug before I poured in the coffee. Usually my coffee is too hot to drink for at least 30 minutes if I close the lid of my mug, which I do because those 30 minutes usually include travel time to school. Because I had the Joulies in the mug and they were supposed to cool it to drinkable in minutes I had to test the claim. I waited five minutes and took a test sip…

Perfect. Maybe a touch on the warm side but definitely drinkable without burning my tongue.

That first day I also drank my coffee slower than usual so I could test the claim that it kept it warm longer. I got to school at 7:30, about half an hour after pouring my coffee, at 11:30 it was still very warm. I left a bit in my mug so I could test it again at the end of the school day. At 3:30 when I was packing to head home I gave my coffee a sip and it was still warm(ish). Definitely not hot anymore, not anywhere near perfect temperature but it was most assuredly not cold.

Ok, so pretty impressive but I still had my doubts. What about in a non-insulated mug? On the weekends and days I don’t have to teach I use a normal ceramic mug and my coffee quickly goes from drinkably warm to cold faster than I can drink it usually.

The next Saturday morning I got out my mug and two Joulies. (I have a big mug…) About two minutes after pouring the coffee was drinkable.I tested it at 15 minute intervals for the next hour and it was comfortably warm for at least the first half hour. The last half hour it seemed to cool more quickly but there was also less liquid in the mug and the Joulies were exposed to the air. I’m not a scientist but it seems reasonable to think that could cause them to cool more quickly.

Overall, I’m really happy with my set of Coffee Joulies and would recommend them to anyone who needs a better way to keep their coffee at the perfect drinkable temperature for longer!

An added bonus is that they’re made in the U.S., keeps your coffee hot and keeps our economy going!

  1. I can’t believe someone hasn’t created these before! It actually makes sense. I am a sipper of coffee and I would love to be able to sip HOT coffee for a long time without reheating!

  2. I have never heard of these but now I need to try them! My husband and I would both love them. I love the design of them as well!

  3. These sound brilliant! I like to read the paper in bed on Sundays while drinking my coffee and it’s almost always cold by the time I get to the crossword puzzle.

  4. My favorite hot beverage is, what else?, coffee! I usually make one BIG mug of coffee in the morning, and of course it’s too hot to drink right away. Then it seems just when I remember to drink it, it’s gotten too cold. So these Coffee Joulies sound like a wonderful idea!

  5. Yes, I would benefit from a set of Coffee Joulies. I could enjoy coffee at the right temperature longer.

  6. I drink coffee often, but it always gets cold before I can drink it. I could definitely benefit from this.

  7. So where have these been all my adult life? I am absolutely amazed by these little gems (okay beans lol), I’m totally going to have to try them asap. I love the White Chocolate Mocha from Starbucks.

  8. This is an awesome idea! I can’t tell you how many cups of coffee have been poured out because they’re too cold. I’d love to try these!

  9. This is the first time I have heard about these. I have problems that my coffee is to hot and I wait to long to drink it and it gets to cold then. These sound like they would be perfect for me.

  10. My favorite hot beverage is coffee. I make it first thing when I get up in the morning and drink it while checking my email. I can get sidetracked going through my email messages and next thing I know, my coffee is cold and needs rewarming in the microwave. I think the coffee joulies would be just the thing to prevent this and I would love to win them so that I can try them out.

  11. I am an all day coffee drinker and would love love love to try these! Maybe I could finish a cup without having to microwave it

  12. Geeze..I’m a spaz! Haha.
    I just out both comments on the giveaway area.
    This is what I get for multitasking too many things.
    Anyway..sorry..this is a clever..genius product.

  13. I have never heard or seen these before, but I could sure use them. I have a cup or two of coffee almost every morning and this would be nice. I could drink at my own pace- fast or slow and still have a good drinkable cup of coffee.
