Perfect Coffee Temperature: Coffee Joulies

Coffee is always more enjoyable if it’s the correct temperature. Too hot and it burns your mouth. Too cold and, well, it’s just cold mud in a mug.

Coffee Joulies were invented to solve both problem. They look like large polished stainless steel coffee beans and are about the size of an ice cube. You put two or three in your mug and pour your coffee over them and the non-toxic liquid inside the shell absorbs excess heat to cool down your coffee to a perfect drinking temperature. As your coffee cools below the temperature of the liquid inside the Coffee Joulies, heat is then transfered back into your coffee. This two-stage process works to ensure that your coffee maintains it’s perfect drinking temperature longer, making for a more enjoyable drinking experience.

Coffee Joulies first appeared on the website Kickstarter, where the creators were asking for 240 orders of $40 or more to fund the $9,500 retooling necessary for a flatware manufacturer in Mexico to setup their factory to mass produce the item. The concept was so appealing that they’ve already received over $123,000 in orders!
Their website joulies.com is currently down, but I’m sure it will be up soon.
Their pitch video from the Kickstarter posting is below.

I personally drink my coffee too fast to take advantage of something like that, but I can see where it would come in handy. I wonder just how well it actually works or how long past the usual cool off time it would keep coffee warm.

I’m with you. Coffee is all about quantity.

Also – they’re so pretty, in a high tech sci fi sort of way, don’t you think?

That is a really great idea. I am a big coffee drinker. I am going to buy some of those and check them out.

Does this product in any way compromise the coffee flavor profile?

For me, it’s all about quality – 1 cup of supremo java is the best way to start a day. I can’t help thinking, though, that when I take that last savoury gulp of expresso, are they going to slide into my mouth? I truly hate being negative, but I can see someone choking on these. I’m going to give them a try anyway, just to see if they really work.
