I bought a bottle of GT's Guava Goddess kombucha last night and forgot to refrigerate it; it's now been at room temperature for about 15 hours and the plastic cap is slightly convex, not flat (I'm certain that if & when I open the bottle, there will be a lot of fizz spillover).
The expiration date isn't until July 2021.
But it's clearly marked as a refrigerated item and yet has been warm for half a day.
Can I drink it?
