The information claiming this chemical leakage stemmed from a University of Idaho student’s masters thesis. The FDA does note that reusing plastic water bottles without washing them could possibly harbor some bacteria. The myth has been busted, but do keep in mind that new and existing research is constantly under review.
In the experiment, bottles of champagne were stored at 6, 12 and 20 degrees Celsius.
The team found that temperature played a bigger role in the condensation of the vapors than they’d previously thought, and it also impacted the way the clouds formed when released from the bottles.
Bottles stored at 20 degrees Celsius ended up losing the customary white-grey cloud as it was replaced with transient blue fog.
The researchers speculated that this reaction was caused by clusters of ice water that gathered after adiabatic expansion occurred in the bottles stored at warmer temperatures.
