Rotten eggs / sulfur smell

Just drank an Island Punch can with a rotten eggs smell (only realized after I took a sip). I don't understand much about the labeling but the bottom says "Best by: 04/04/2027 0247 09 RR" (if that offers any traceability). I imagine that batch might've been affected, whether from bad sealing or something in the liquid itself.

I will be smelling my drinks beforehand now.
