With this innovative wine conserving system, wine from partially used bottles is still preserved for weeks, months, or even years. For this, the product is placed on top of the bottle and its needle pushed through the cork. A green light ring then indicates that the wine is ready to be served. As the wine is poured from the bottle, it is replaced with argon, an inert gas used by winemakers. Model Eleven can be controlled via Bluetooth with the corresponding app.
