What does rotten grapefruit smell like?

A rotten grapefruit smells extremely unpleasant. It's a combination of several foul odors:

* Sour and Fermented: Think of spoiled milk or aged cheese, with a sharp, acidic edge.

* Putrid and Decaying: Like rotting meat or garbage, with a pungent, almost chemical smell.

* Bitter and Fruity: A faint hint of the grapefruit's original citrusy scent, but twisted and distorted by the decay.

The exact smell can vary depending on how rotten the grapefruit is and the specific type of grapefruit. Some people describe the smell as similar to moldy fruit or stale vomit.

In short, it's a powerful, repulsive smell that you'll likely want to avoid at all costs!
