This unique decanter allows you to aerate, serve and even re-bottle unfinished wine. The Inversion Aerating Decanter is designed with an ingenious stopper-top, which allows the whole decanter to invert and seal to the mouth of the wine bottle. Attach the wine bottle and then watch and listen to the wine aerating into the decanter – ready to serve & enjoy! To store any remaining wine for another day, simply reverse the process and it’s back in the bottle!
