How to Keep Your Coffee Hotter Longer

Adding cream cools the coffee immediately and substantially, even if subsequent cooling is slower.

Not if it's the same temperature as the hot coffee.

You keep your cream at temperatures that high?

I don't drink coffee.

Coffee reduces one's ability to hold dead on a target at 1,000 yards.

Which is the exact reason one should stop drinking coffee immediately following a traumatic break up....

.

Initially you may miss your ex terribly... but don't worry, your aim will improve!

.

You are so right!

When I go target shooting, I stop drinking tea and coffee some days before....

Perhaps, when you like it warm, you should drink it warm?

When these few minutes later you feel drinking warm coffee again, get a new one. Buy a thermo can, a heater, or preheat your cup before pouring the coffee. And don't put the chocolates too close. They might adsorb the radiated heat and melt.

In prevention logics:

if something is a problem: - rule 1. eliminate the source - here take no coffee?

rule 2. isolate the problem - perhaps keep it warm, put it in a isotherm container.

Once I was in Isreal asking for coffee. It didn't taste well. I asked: when did you brew this coffee? Yesterday !!!

I said I don't want coffee from yesterday. but coffee, made today

The answer:///???

Then................

Come back tomorrow

And now the grammar:

hotter longer- what is this? The same as longer hotter? Is this the new English way to curse?

You can keep 'longer"

but you cannot keep "hotter". Hotter is when you add energy. When you "act" or inflict a situation to act.

But my English language is still under destruction

The Engineer's Notebook

The Engineer's Notebook is a shared blog for entries that don't fit into a specific CR4 blog. Topics may range from grammar to physics and could be research or or an individual's thoughts - like you'd jot down in a well-used notebook.

The off topic donor may perhaps read the basics of the blog? It is above the O P.

I put it right for you - your remarks are absolutely valid.

Once I was in Isreal asking for coffee. It didn't taste well.

1. I said, "Waiter, this coffee tastes like mud."
2. His answer: "Why? It was ground this morning."
3. Yes, Israel is, in fact, real.

Good points

.

but

.

they're not really improved

.

by adding extra periods

.

to create additional spaces between them.

.

IT'S ALMOST AS ANNOYING AS ALL CAPS.

The text editor has a bad habit of crushing whatever I write down to one block paragraph.

.

The periods in between are the only way I know to insure it doesn't happen.

.

I use one "." for spaces between sentences and two for a new paragraph just to make it readable.

.

.

Sorry, if it is irritating. That is not the intent. I plan to continue though (until I have a better solution), because I find the monoblock style sufficiently unreadable that if forced to choose, I would simply not post.

.

I don't hold high hopes for finding a solution quickly, since they haven't been that stellar in fixing the other problems on CR4 recently (and I don't want to distract them).

This "explanation" is not believable; others have no problem with composing correct paragraphs.

Wait. Because you have no similar problem, and no one has complained to you with a similar problem, you assume that no one else has the problem, and that my explanation is not believable. Your incredulity is difficult to believe. There are numerous factors to consider, not the least of which it the type of browser being used. Why would you suspect I would be trying to deceive you? What benefit could I hope to gain with this absurd style. It is not quicker to write, it certainly doesn't give my statements any air of professionalism. Okay, just for you, I am abstaining from my period-work around. Is this better for you?

Yes. Your current paragraph is properly composed. Thank you. If your browser is giving you trouble, ditch it and get another. Thank you again.

Exactly.

That is just the problem. It wasn't composed as one paragraph. There were a couple times I hit enter to separate the groups of sentences, but it all comes out as one block. That is fine for short discourse, but anything longer is unreadable. I can't be certain but I think you might have even complained at one time of people not using spaces. Are the periods-for-spaces truly that annoying to you? Also if anyone else is particularly annoyed at the non-standard style I have adapted as a work around, please voice your opinion. I had no idea I was grating on nerves. I would have written one comment off to someone having their panties in a wad, but with two CR4 members I respect suggesting the format of my comments is offensive, I have to reconsider.

LOL...

of course you can hit the edit button

and separate with spaces as you desire...

sure... but it just reverts to the same thing.

On second thought, I'll type in whatever bastardized work-around format I please.

.

Anyone who's sense of composition and style is too highly refined to bear glancing at the method I use to put space in can simply scroll past. For those so delicate, when you are scrolling down and see 'Truth is not a....' just close your eyes tightly and finish the sentence in your head as 'concept I am willing to consider without prim and proper styling and composition', as you quickly scroll past what would surely scorch your fair sensibilities.

.

When have I ever lied to you, or even given you strong suspicions that I was attempting to foist some falsehood in earnest? Why move right away to the absurd idea that what I am saying is not true, and that I have some secret ulterior motive for typing in this awkward fashion?

.

Thank you style-nazis, you have removed the burden of this tedious work around. It is no longer a tiresome requirement, but instead an act of defiance.

.

.

.

.

Does it hurt yet?

.

.

.

.

Come on now chaps.

. . . . . . .

. . . . . . .

Stop all this fighting in public.

. . . . . . . .

. . . . . . . . or something like that.

. . . . . . . . .

(Takes far longer than just ordinary typing. Jeez....... )

Chrome used to do that to me, back when it first came out.

I always wondered why you did that.

My coffee cools off because I add 2% milk out the refrigerator, which is cold. I drink it out of a giant mug that holds about a liter. Once it goes to room temp, I sometimes add ice to it and drink iced coffee.

What browser are you using? Safari, for example, doesn't support any formatting you put into the text editor.

Put this tag at the beginning of a new paragraph to make a line break: (p) - but use brackets instead of parentheses [ ]

Thank you. That has worked on my mobile phone browser in the past. I may switch browsers or might try that solution, but for now, I'm remaining in defiance mode.

.

I do appreciate your assistance.

I have the same thing on my ipad, and I have to put in [/p] to start a newline. Don't know why it works now, maybe because I'm on a laptop

It doesn't bother me.

"How to keep your beer cooler longer"

Too easy....

http://gadgetsin.com/thanko-usb-can-cooler.htm

Well if you really wanted a beer it doesn't matter if it's warm or cold....

If the beer is free....... Then I really don't care.

I have to disagree! I can't stand warm beer! I prefer my wine cooler than many others do, but beer needs to be as close to 0°C as possible. (Beer does NOT freeze at 0°C).

I was told by a beer conisuer (bartender/ bar owner that) warm beer was better for you. I don't know if that was true.

But I did recall, a cool beer, not cold, not warm but a cool beer goes down best......... Unless your eating chili..... Then one in a frosted mug works.

Calm down and get a good vacuum bottle, coffee stays hot and does not get bitter as happens when left on heat. Take a container of moo with you if that is your preference and same for the white death ( sugar). This way no one has to agonize over how or why it cools unless you think it will stay hot for a day or so.. cheers and happy coffee break.

Or you could have used a thermos flask

Or drink it while it's hot.

Sometimes by the time I get up my coffee is cold. I just heat it up in the microwave. It also compensates for the cooling effect of adding the cream. And I can consolidate several cups into one large mug.

If god wanted us to drink cold coffee he wouldn't have given us microwaves.

We are mostly engineers here so this should be a practical solution for many. Note. I cannot take any credit, Ivan Pavlov got here before me.

Write a simple program on your computer that rings a bell every 45 seconds (sophisticated programmers can make this time adjustable). Each time the bell rings take a sip of coffee. The coffee will be finished before it goes cold.

'....Write a simple program on your computer that rings a bell every 45 seconds ........Each time the bell rings take a sip of coffee.The coffee will be finished before it goes cold....'

.

Oh great! ...and after the coffee is finished we get to look forward to the rest of the day filled with a bell followed by air-entrained empty sipping every 45 seconds!

.

.

Perhaps a slightly more involved program (written on a computer, or as a mental note) would be more useful.

This does not pose a serious problem for me. I now work mostly from home and I have an understanding wife. Regardless of whether preceded by a bell or not, if she hears thumping caused by my banging my head against the wall, she brings me another cup of coffee (or tea).

As Pavlov discovered, it is largely a matter of conditioning.

Incidentally, I posted this comment without her seeing it. I may be a fool but I am not that stupid.

That is funny. Until the last line, I thought you were making reference to her conditioning you with the reward of tea/coffee....

.

Kind of reminds me of that song 'Wrapped Around Your Finger' by The Police.

If the dog has Pavlov conditioned, does it want Pavlov to know that he has been conditioned?

I don't know the answer...

.

but I am salivating with anticipation at the prospect of knowing the answer!

Just as long as the coffee doesn't taste nutty.

If you want it to stay hot longer, use a Styrofoam cup with a lid. I think the dominant mode of heat transfer is not radiation, but a combination of conduction through the cup, convection both within the coffee and in the air around the cup, and evaporation.

Styrofoam .............. oh, oh....

Coffee cools like you say through radiation from the cup. More than evaporation. I never think' i'll hold my hands in the steam from that drink and warm them up, it's 'put your hands on the vessel' for most heat.

there are some simple tricks, and an insulated cup is one, although part of the pleasure is the heat of the vessel on lips, another is drink latte, the foam is an insulator, Use dried coffee whitener. OK, it keeps the coffee at the hottest, as opposed to milk or cream, so it goes colder at a greater rate, but that heat is initally transferred into the container, which therefore keeps the coffee warmer. Only put it on an insulated surface. Put it on stone and its cold very fast.

Make it in the mug in the micro. best for 100% milk coffee. There is no loss of heat into the vessel, as with kettle water into cold cup, as the vessel is heated with the liquid. Use warm milk for your drink, at least not refridgerated. It makes a difference. Drink smaller drinks. Coffee cans are v small cups, specifically for coffee, although I don't suggest going that small, but two small hot drinks over an hour say, are better than one hot then lukewarm big one.

My hot drink story,.. spent all day as a youth moving a sandstone wall, pulling it down, loading it up, unloading,.. on a farm. come nightfall, sitting round the table, with a cup of tea, it never seemed to go cool enough to drink, after half an hour it was still piping hot to the touch! Eventually cool enough to put to my lips,... tepid!! Yep. I had worn the skin off my fingers, and they were telling me it was really hot when it wasn't.

CNC jim

If I'm at an outdoor event like an auction, and its bitter cold, I'll buy coffee to warm my hands.

'....Coffee cools like you say through radiation from the cup. More than evaporation. I never think' i'll hold my hands in the steam from that drink and warm them up, it's 'put your hands on the vessel' for most heat.....'

.

The type of heat transfer you describe above is not radiation but instead conduction.

.

The actual heat lost via radiation (difference in what is radiated out vs in) for typical coffee cup conditions is exceedingly small compared to other types of heat transfer.

I'm ok with the reasons #1 and #3, but not with #2. Ok, by adding cream the temperature will drop immediately but, after that, the temperature will further drop according to Stefan-Boltzman's law. Concerning the other cup (black coffee), its temperature will, also, drop in the same way (according to Stefan-Boltzman's law). So, its temperature will always be higher than the temperature of the other cup (coffee-cream). (Of course, this is valid if you ignore the other 2 reasons #1 & #3.)

Not coffee but the principle is there.

Years ago, we did not have running hot water, we boiled it in a kettle, poured it into the basin with some cold to get the right temperature for shaving. My brother and I had different techniques:

I ran some cold water into the basin first so that I did not waste the heat by over warming the basin, figuring it would radiate some heat to the air if I did.

My brother poured the boiling water into the basin before adding the cold water. He figured that the basin would store some of the heat and release it back to the water when he added the cold.

We didn't resolve which was the better method.

I remember doing that! More important than the order of adding hot and cold water, is how much water to boil (or heat, not necessarily boil). Any water heated but not used is wasted energy.

But, if you're cooking on a wood stove, does it matter?

Good point! Now that you mention it, I did only use that method when heating with wood, most recently while camping.

I like my coffee with full cream milk (not cream, though many mean milk when they say cream!) and hot. I use a very simple method to achieve this:-

Boil water and use it to heat up the coffee machine jug.

Before making the coffee, I pour that hot water into a great thick-walled mug to heat it up as well.

When the coffee is finished/ready, I throw out the hot water from the mug, pour in the milk (cold) and fill with fresh coffee.

Drink.

Great hot coffee.......
