Gulfstream

Release the full flavour of your grapes!

Gulfstream guarantees controlled and effective temperature regulation for your harvest. The immersion principle allows instant and uniform heating while preserving the quality of the grapes.

Operating principle

Regulating the temperature of the grapes uses the immersion principle and dynamic cross-flow drainage: the harvest is soaked in a bath of heat-transfer fluid and drained by drums allowing the transfer.
The processing chain is entirely controlled by a programmable logic controller (PLC), which regulates the temperature when the grapes leave the heating chamber depending on the type of vinification chosen (hot pre-fermentation maceration: 72°C, Flash Detente thermovinification: 85°C).
A simple and intuitive touchscreen enables the operator to control the various operating parameters (temperatures, maceration time) and informs the operator of the Gulfstream status.

Heating that protects the grapes
  • Protects the whole grape harvest
  • Quickly extracts all the phenolic compounds
  • Reduces the amount of pyrazine and geosmin
  • Denatures harmful enzymes (laccase, polyphenol and oxidase)
  • Gives well-rounded, supple and aromatic wines
More value added to the harvest
  • Reduces labour costs
  • Reaps the value of 100% of the harvest
  • Up to 35% energy savings
  • Treats spoiled grapes (Botrytis)
Versatile for use in all situations
  • Full range
  • Versatility:
        Cold and hot temperature control
        - Feeds in whole clusters or destemmed grapes
  • Heating of the grapes for Flash Detente
  • Can be used with well-drained grapes (heats the dry matter)
Automated process at your fingertips
  • PLC (programmable logic controller)
  • Simple and intuitive touchscreen
  • Automated process

GULFSTREAM

The large evaporation surface of the Gulfstream eliminates a considerable proportion of unwanted compounds from the musts (methoxypyrazine, geosmin and others).

Analytical measurements have shown the effectiveness of this evaporation process.

In addition, the process of heating the harvest by immersion helps protect the grapes by treating all the berries to destroy harmful enzymes.
