I’m assuming you’re talking about homogenised and heat treated milk from a carton and not fresh from a cow. Because there’s a HEAP of different stuff going on if it’s fresh.

Do you mean if it’s left out to warm up a little? Because temperature really affects the taste of things. Cold things send a different reaction from the nerves to warmer things…. part of the taste is the sensation in your mouth.

Lots of taste is about the smell. The warmer the milk the more you can smell it because there’s more molecules in the air to smell.

Because milk is ‘fat’ based warmer fat is going to mingle in your taste buds better than colder more solid fats.

Or are you taking more long term ‘left out’… it’s slowly decomposing. The milk solids and liquids are separating, Bacteria is multiplying… and they are quite smelly and tasty in their own right.
