Improve your wine's bouquet instantly with our Cooling Aerator! The cooling rod is filled with a non-toxic gel that keeps your wine chilled. All you need to do is place the rod in the freezer for approximately 2 hours and you're good to go! To pour yourself a flavourful glass of wine, attach the aerator and the rod together and place the rod into the bottle of wine. The rod will cool your wine while the aerator will improve its bouquet and flavour by injecting air directly into it. It compares to 30 minutes of decanting! The result? A tremendously improved glass of wine in just a few minutes.
