I wanted to do a small followup post here to my post from earlier this summer: The Best Travel Mug To Keep Coffee Hot.
In that post I pretty much said that the Thermos Stainless King travel mug was the best travel coffee mug for keeping coffee hot all day long. What I didn’t provide in that initial post was the proof.
Because it’s such an important feature of a vacuum insulated mug I wanted to follow the post up with a test to proove that the Stainless King is indeed the best travel mug of it’s kind as of 2013.
You’ll see in the video below that I pitted the Contigo Autoseal, The Oxo Good Grips, and the Trudeau Umbria desk mug against the Thermos Stainless King to see which one could keep boiling water hot the longest.
In the test I poured hot water into the mugs and then sealed them all for about 8 hours and 15 minutes. I then opened them up and tested the temperatures with a meat thermometer.
The Thermos mug won by a land slide and the funny thing was that the Thermos mug I used in the test was almost 3 years old compared to the other mugs ranging in age from a few months to brand new.
I’ve featured the Thermos mug prominently on this site as the best travel coffee mug hands down so hopefully this test helps confirm that with you.
And for those that didn’t watch the video note that after 8:15 boiling water sealed in the Thermos mug measured at 134 degrees, a temperature I would still consider to be a good coffee drinking temp.
