Sparkling process pilot plant

SMT-M/EV

Sparkling wines are wines enriched with carbon dioxide.
This enrichment can be obtained by a refermentation or by a direct addition of this gas, in artificial sparkling wines.
One of the commonest methods is Charmat method that uses pressure-resisting fermentation tanks (autoclaves) where sugar and yeasts are added to the wine after being refrigerated.
After this refermentation process that can last some days up to some months, wine is refrigerated, filtered and bottled without any pressure loss.

Training program

  • Check of end product versus the following operating parameters:
    • operating pressure
    • refermentation times
  • End product analysis:
    • organoleptic examination
    • alcoholic strength
    • total dry extract
    • sulphur dioxide
    • acidity
    • reducing sugars
    • wine stability test
    • determination of carbon dioxide
  • Determining the best conditions for sparkling process
