Grape Cooling

Process Description

In order to prevent unwanted microbiological activity during the grape harvest, the temperature of the berries is lowered. Cooling with dry ice is especially recommended here.

Messer Solution

The fresh grapes are cooled immediately after harvesting with dry ice. Both fixed and manual snow horns can be used for this purpose. Alternatively, dry ice pellets can be added manually. The cold gas protects the berries from unwanted premature fermentation.

Mash cooling with dry ice provides, in particular, the following advantages:

  • Efficient and rapid cooling
  • Displacement of oxygen
  • Operator-friendly controls
  • Low space and personnel requirements
  • Low maintenance costs
  • Affordable operating costs

Messer helps with the selection of the process and the provision of the technical facilities and carbon dioxide required.
