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.
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.
