I really like this stylish stainless steel Wine Thermometer temperature control cuff. To enjoy a perfect glass of wine, different wines should be served at different temperatures and this takes out all the guesswork. Simply slide this thermal band over the bottle and the temperature will automatically display without batteries. Printed along the cuff is an easy reference guide for different types of wines and if the temperature appears in the right window for the type of wine in the bottle, it's ready to drink. A handy and very easy to use wine tool.
