Is there a scientific reason why a cold drink in a mug is wrong?

Cold drinks in mugs not enjoyable

no

mug, jug….

Fill a coke can with water and drink it. Weird.

I like cold milk out of a mug.

Hope that helps.

Receptacles for cold drinks have traditionally been thinner than for hot. When raising the drink to your mouth, the rim thickness and indeed the weight of the receptacle, combined with the temperature is always something of a shock to the system.

In other words, wrong indeed.

nothing feels better than drinking red wine from a mug 🙂

Mouth, rim and shock should never appear in the same sentence.

None. I do find a latte in a glass a bit odd though.

In theory, and i think this is right, all drinks should actually taste better being drunk out of a receptacle with a thin lip, as you take in more air with the liquid and this in turn increases your ability to obtain the full flavour of something. This is why tea is better out of a fine bone china cup and why wine or drink tasters “slurp” as they drink to take in more air with it (but i might be wrong!)

Fine bone china cups are fine because a thick bone china cup would shatter when you poured boiling water in it. N’est-ce pas?
