How long is coffee with creamer added safe in a thermos?
I'm not sure if this or this questions' answers satisfactorily cover my question but I am seeing a lot of answers that talk about the shelf-life of coffee and say things just "change" when adding sugar or dairy.
I make about 20oz. of coffee each morning and put it in a thermos. I then add my creamer to this at home and take it to work. Most days I get through it within a couple hours of being there, but some days I don't go through the whole container and the coffee is still pretty hot by the time I get home (go thermos!). I understand that if it was plain this should be fine, but does the dairy creamer break down over the day to the point I shouldn't be consuming it by the time I get home (about 9 hours after brew time) given it has been kept pretty hot most of the day ?
If I should be tossing this sooner by a certain time when is that? Does keeping it hot prolong life beyond the 2-4 hours in the danger zone I am seeing on other posts?

The clock on the danger zone starts when the food temperature drops below 60 celsius. It should be 4 hours for coffee - two hours are for meat, where it is assumed that bacteria in it have had some chance to grow while it was being butchered, transported, and stored in a supermarket. In coffee and creamer, there will be no bacteria growth at all in the ingredients, it will start after you have brewed the drink and mixed in the creamer, and the temperature has fallen below 60.
If you want to go by the book, measure the temperature of the coffee inside the thermos 5 hours after brewing. If it is above 60 Celsius, then it is still safe up to 9 hours after brewing. Do it on several days to have a significant result.
(For those of us on my side of the pond, that's 140 degrees Fahrenheit. )

The short answer: probably. If the coffee already has milk or creamer in it, you shouldn't drink it if it's been sitting out unrefrigerated for too long. But while day-old coffee likely won't put your health in jeopardy, but there are still some good reasons to get your cup of caffeination piping hot.Best Coffee Thermos 2021 | Top 7 Coffee Thermos on Amazon

Answer 2
The thing about dairy is that it comes with a huge bacterial load, but it's all stuff that's relatively benign to humans (assuming it was originally pasteurized). When it goes bad it gets chunky or stinky or both, and that's usually gross (sour cream, yoghurt, buttermilk, etc, being the exceptions), but not terribly harmful.
That naturally occurring bacteria also does a good job of suppressing the growth of other, more hostile, bacteria. It just out-competes it. Nearly all dairy products are based on this. Cheese, yoghurt, sour cream...they would be impossible to eat safely if it were not true.
All that being the case, I'd say that as long as your beverage still tastes and smells good, it's not going to hurt you: the bacteria that's going to blow up first will definitely change the flavour. My original answer to that first question was based more on long term storage.
The whole "Danger Zone" thing is based around uncertainty over your bacterial contamination. After a couple of hours warm, something will have established a sizable colony. In this case, it's probably going to be streptococcus lacti, and it's not bad for you.
Answer 3
I usually don't answers questions but since I'm a coffee junkie I felt inspired. As I write this at 9:30 Sunday morning I'm sipping on a cup of coffee that I brewed at 10:am on Saturday morning but have kept in a thermal carafe since. I poured a cup, (which was still a little warm after almost 24 hours), and nuked it in the microwave for 2 minutes to reheat it, then added my usual splenda and powered creamer and other than a slight stale taste, (which I always get when I reheat lukewarm coffee in a microwave), it is fine. I wouldn't reheat coffee that has been left out uncovered overnight, but I've never had a problem when I've reheated coffee that's been stored in a carafe even on the rare times when it was from a pot of coffee that I brewed but wasn't able to drink even up to 24 hours later. Finally I will apologize to the true coffee connoisseurs out there who are cringing while reading this.
