So the US State Department has issued a warning about tainted alcohol in Mexico after the latest incident at a 5* Iberostar. On almost every trip we have made to Cancun someone we were partying with made a comment about the alcohol tasting off. What I've experienced seemed to have been a much lower "proof" alcohol than I am used to at home. Tainted isn't the way that I'd describe it...........more like watered down. Has anyone else experienced anything similar?
