Fresh milk should have barely any odor. It will smell clean and slightly sweet, but without a strong or noticeable scent.
In more detail:
- Minimal Odor: The most defining characteristic of fresh milk is the lack of a pungent smell. It shouldn't overpower your senses.
- Slightly Sweet: A subtle sweetness might be present, but it should be very faint.
- Clean Scent: Essentially, it should smell clean and neutral, not carrying any off-putting odors.
Contrast this with spoiled milk, which has a distinct, sour, and unpleasant odor that signals it is no longer safe to drink. The absence of this sour smell is a good indicator of freshness.
