Signs Sparkling Water has gone bad
- Doesn't really spoil — just goes flat.
- Off plastic taste if stored very long is the main quality issue.
Discard immediately if
- Bottle is bulging
- Visible cloudiness or particles
Why guidance varies
Pasteurization method (HTST vs. UHT vs. cold-pressed), preservative content, and container type (carton vs. plastic vs. glass) all change shelf life dramatically.
