General

Course Contents

  • The concept of clarity and colloid phenomena.
  • Interventions and manipulations for the clarification and stabilization of wines.
  • Wine clarification techniques. Principle of filtration and centrifugation.
  • Stabilization of wines by physicochemical methods, but also by the use of oenological substances.
  • Study of the mechanism of crystallization and precipitation of tartaric acid salts.
  • The application of the electrodialysis technique in the wine sector.
  • Metallic haze (iron and copper) in the wine. Their prevention, treatment and management.
  • Redox potential of wines and the factors affecting it.
  • Aging of red wines and aging techniques.
  • Study of the origin, nature and consequences of the main organoleptic deviations in wines.

Educational Goals

Students become familiar with the various processing and stabilization techniques of musts and wines, as well as with the use of appropriate clarifying materials. They understand the concept of wine aging and the conditions that must prevail during it. They also learn to recognize and deal with organoleptic errors and deviations.
