We Tried 7 Different Coffee Mugs To See Which Cup Really Keeps Liquid Warm The Longest

When it’s cold outside, there’s no better way to warm up than with a hot beverage. Unfortunately, hot drinks don’t stay that way forever and eventually lose the cozy appeal.

The truth is, there’s nothing worse than lukewarm coffee or tea in your mug. That’s the kind of stuff that belongs down the drain, not in your stomach.

To find out which type of mug retains heat the longest, we lined up seven mugs made of different materials and put them to the test.

Mugs come in all shapes and sizes. The types we tested are: classic ceramic, tin, Styrofoam, glass, plastic, paper, and stainless steel.

We filled each mug with boiling water — 212° — and then waited half an hour to see how much the water cooled.

Most of us trust a ceramic mug to keep our drinks warm, but it turns out that material probably shouldn’t be your go-to after all. The water inside the ceramic mug dropped by more than 100° in just half an hour.

Another disappointment came from a tin camping mug, which also lost a ton of heat in just half an hour.

Styrofoam and paper mugs didn’t fare as well as one might hope, either. Although no one should have high expectations for anything disposable.

With that said, the remaining mugs and results may surprise you — and influence your mug of choice from now on. Watch the video below to find out which mug wins out.
