Chill & Warm Wine Bottle Wrap 5 "Very quick!" Spencer 20 November 2012 Tried another version that had to be charged in boiling water for 15 minutes which nobody remembered in time! This one just goes in the microwave for about a minute and then round our bottle of red to warm it just right. It's also very quick to chill a bottle of white when you put this jacket in the freezer. Good value.
