How to Tell If Pineapple Juice Is Bad: Quick Tips for Spotting Spoilage

Okay, so I bought a big bottle of pineapple juice the other day, the kind you get from the grocery store. I opened it up, poured myself a glass, and it tasted pretty good. I’m not a huge juice drinker, but I’ve been trying to get more fruits in, you know?

Anyway, I put the bottle in the fridge and forgot about it for like, maybe five days. When I remembered, I pulled it out, and I was like, “Hmm, is this still okay to drink?” I had no idea how long this stuff lasts. So, I did what anyone would do – I started sniffing it. It didn’t smell rotten, but it had a slight, tangy, almost wine-like smell. I thought that might just be how pineapple juice smells after a while, but I wasn’t sure.

The Experiment

First, I poured a little into a glass and looked at the color. It looked a little darker than I remembered, but not super different. Then I swirled it around, and it seemed a bit fizzy, like when you shake a soda a little. That got me suspicious. Next, I took a tiny sip. It tasted a little sour, not like when I first opened it. And it had a little bit of a fermented taste to it, you know, like it was starting to turn.

The Conclusion

So I decided to throw the whole thing away. I really don’t like wasting food, but I definitely didn’t want to risk getting sick. I did some reading online after, and it turns out pineapple juice can start to ferment pretty quickly after you open it, especially if it’s not refrigerated properly. From what I read, if it starts to smell off, or gets fizzy, or changes color a lot, it’s probably best to toss it. If you see any kind of mold, that’s a no-brainer. I also read that if the bottle is bulging or leaking, that means the juice is fermenting and producing gas, so you should definitely not drink it.

  • Check the smell
  • Look at the color
  • Check for fizziness
  • Inspect the container for any bulges or leaks

I’m glad I trusted my gut and didn’t drink more of it. I learned my lesson, though. Next time, I’ll probably just buy a smaller bottle, or maybe just eat actual pineapple instead of drinking the juice. Or if I do buy a big bottle again, I’ll make sure to drink it within a few days.
