Realistically, how many hours does this mug keep coffee warm for?

I actually have not used this mug for coffee, I have however used it for water and I'm not kidding when I say water stays cold for up to 24 hours. It's amazing. Sorry I couldn't help with the coffee question.

I am tempted to just answer "hours", but of course "it depends" (sorry!). I think if you just pour from a freshly brewed pot of coffee into this awesome Nissan-Thermos stainless-steel mug, you should easily get at least 2 or 3 hours of hot coffee. Personally I drink 14 oz. of coffee much faster than that! But the real trick to this double-walled, vacuum construction is to PRE-heat the cup! First, run hot water from your tap (as scalding as you want) and then pour it into the cup, close it, and set it aside while you make your coffee. I assume the vacuum (?) stainless-steel gets heated up. Then, when you dump out the hot water moments before you pour your hot coffee in, it's almost as if you have a heated thermos! Using this method before a 2 hour commute I don't even notice a decrease in temperature at all. It seems to me that it will then stay hot 4 or 5 hours or even more! Obviously I am a huge fan of this "Nissan" Thermos brand.

Hello George, here is the secret....I pour boiling water into this mug first thing in the morning while I make my breakfast. Let it sit for 5-10 minutes with the lid closed to fully pre-heat the mug. I then dump the hot water, pouring through the lid to pre-heat the lid.I then pour extra-hot coffee into the thermos and seal it up tight. I then have my coffee break at work, 3-4 hours later and it is too hot to drink! If I waited longer to open it, I'm sure it would be nice and hot!

I can't tell. It keeps coffee warm for about an hour! You fall in love with it.

Yes! As a matter of fact, I am drinking my second cup right now, 30 minutes after making the coffee. It's hot! The warmer goes off automatically after one hour.

Haven't timed it but longer than any other thermos I've had in the past. If I fill it up in the morning before 7 AM it is still warm (I wouldn't say piping hot) after 6 PM.

I have only kept coffee in it for a max of 2hrs. Coffee maintained at a nice temp.

Around an hour. The plastic lining changes the flavor of coffee however, I would highly suggest a thermos with a double walled stainless steel lining.

Hours. Don't know how many exactly but if you put undrinkably hot coffee in it, it takes forever to cool enough to drink it. I love this cup

I put it in @ 350°f for 30 mins. Can't attest to anything over that. These are great mugs though.

Yes, to both questions. It keeps the coffee hot for longer than an hour, but I've never actually paid attention to how much longer.

It varies with the beverage and whether or not you used hot water to heat up the mug before you put your beverage into it. Good 4 hours sometimes longer. Imagine it would be shorter time if in a cold area. I keep my car warm.

My coffee starts to cool down about 30 minutes after I fill it. And that is literally just starting to cool. Stays warm for a couple of hours. I hope this helps

The thermal carafe will not reliably keep the coffee hot for more than 2 hours. BUT, it never lasts more than 30 minutes in our house so it has never been an issue.

After the coffee maker shuts off, automatically after about two hours, I would just reheat my cup in the microwave. Quick, easy, and you can control the temperature just by figuring out how long to reheat it. Usually 1.5 minutes is more than enough. Also, I keep mine in an insulated mug and it stays hot a long time. We have switched over to Keurig and love it, but oddly enough, you still have to reheat the mug if you leave it idle for awhile. Hope this helps!

Debbie, Truthfully, I purchased this for a gift. The person I gave it to said it keeps her coffee very hot on the way to work, she lives 50 minutes from work. She also stated when she arrives the coffee/drink is still as hot as when she filled it. Hope this helps, Spencer

Agree with many other responders -- stays warm for maybe 8 hours -- but definitely not hot after that. Insulation is present, but it's not like a thermos at all.
