A question for the physicists - now with poll
« on: April 17, 2014, 08:55:05 am »
When I make a hot drink, I put the milk in according to how I want the drink to taste.  So after the tea has mashed, or first for coffee to stop the boiling water scalding the coffee.

When BH makes a hot drink, he doesn't put the milk in until he's ready to drink the drink.  He says that as soon as the milk goes in, the drink will cool down so fast you need to drink it straight away.

So my question is this. 

If you have a freshly-made hot drink, and some cool milk, and you are going to drink that drink in 10 minutes time, which is cooler when you drink it?  The one you put the milk into straight away, or the one you only add the milk to at the point of drinking?

they both lose heat at the same rate (it is a linear function) so the one that the milk goes in first will be cooler over all as its effective starting temperature is lower...

milk first will be cooler

Another question

Why does anyone put milk in coffee ???????????

And yet another

Why is dandelion coffee horrible when its almost cold ???

Question - why would anyone want to drink coffee made from dandelions?  :innocent:

It won't make any difference to the temperature of the liquid which ever way you do it.  Although tea may brew differently if milk goes in first but that's a taste thing not a temperature thing.


If you perceive any difference then it will probably be in the temperature of the mug itself (or whatever container is holding said drink).  Different materials absorb / hold / lose heat differently.

Because it was horrible when it was hot

Okay, I wish I hadn't included the 'Don't care' option because we're all choosing it.  Hrmph.   :D

Agreed but I reckon if you let black coffee stand 10 mins before drinking and then add cold milk it will be cooler than if you put it into scalding hot coffee at the start.
But saying that I like mine made with hot milk anyway :innocent: just to add another iron in the fire :stir:

Cooling depends on the difference in temperature, therefore hot coffee in contact with air will cool faster than slightly less hot coffee (if milk has been added at point of making), so the cooled black coffee will then get colder when the cold milk from the fridge is added.
I have only just agreed with OH that adding milk before the coffee, avoiding scalding, does actually taste better though!
I struggle to drink mine hot though, so usually add a little cold water to cool it even faster, or end up leaving it lying around until its tooo cold.
And I agree with Mandy, if I can't get at goats milk, it has to be hot milk!
