For your well-structured wine


Knowing when to start your grape harvest determines the resulting quality of your wine. To make sure that the ripeness of your grapes is perfect, it is best to check the sugar content of your grapes and thus ensure the first quality step in winemaking.

In combination with the Wine Meister smartphone app for iOS and Android, the SmartRef determines the sugar content of your grapes. For an optimal alcohol content prediction in finished wine, it additionally determines the potential alcohol content of your grapes based on Brix or Oechsle.
