This is one thing every wine connoisseur should have. Designed to help you properly store fine wines, the Cloer 9870 wine bottle stopper features built-in thermometer and automatic pressure sensor. The wine bottle stopper fits on any wine bottle, attaching itself snugly using vacuum suction. The Cloer 9870 also has an LCD display that shows the wine temperature while a timer tells you how long the bottle has remained sealed.
Temperature can be adjusted in either °F and °C. The topple feature prevents wine from being sucked in. All you need to do is place the cap on an open bottle and the Cloer stopper automatically turns on. The automatic pressure sensor provides longer seal. Uses 2 ‘AAA’ batteries. Price is around € 25.
