If a wine is too cold or too warm you will not be getting the full flavours that were intended.
The Kelvin K2 sends the wine temperature information to your smartphone (often from inside your refrigerator) . The free iOS or Android app then monitors your wine as it is chilling and provides as much or as little information as you need to get the best from every bottle of wine
If the receiver shows red, the wine is too warm so put it into the fridge,
If the receiver shows blue, the wine is too cold so let it warm up naturally.
When the receiver shows green the wine is at the ideal temperature and you will get a perfect balance to all the constituents like body, acidity, tannins and alcohol. You will then get the taste of the wine that the winemaker was expecting you to have.
