How to tell if rosé wine is bad?

I'm often faced with the dilemma of determining whether a rosé wine has gone bad. Could you offer some pointers on how to identify spoiled rosé? Are there specific signs I should look for in the color, aroma, or taste? I've heard rumors about checking for mold growth or unusual sediment, but I'm not entirely sure what to expect. Could you clarify what these indicators might look like? Additionally, is there a recommended shelf life for rosé, and are there any storage tips to ensure it lasts longer? I'd appreciate any insights you could provide on this topic.
