Language of instruction : In English
Post-vinification
- Importance and objectives of wine clarification and stabilization.
- Identifying main colloidal instabilities in wines and assessing risks, along with stabilization methods.
- Theoretical and practical aspects of wine fining techniques.
- Principles and control of various unit operations for wine (must) clarification in oenology (centrifugation/floatation, dead-end filtrations, cross-flow microfiltration).
- Understanding tartaric salt crystallization in wines : origins and stabilization techniques (nucleation, crystal growth, impact of wine constituents, tests like TID, Tsat, ISTC 50, cold stabilization, electrodialysis, additives).
- Microbiological stabilization methods (membrane filtration, flash pasteurization, pasteurization, hot filling, tunnel pasteurization).
- Use of SO2 and other additives.
- Glass and PET bottle production, bottle inspection, and bottling processes for glass bottles, PET bottles, Tetra Pak, Bag in Box, and kegs. Additional processes like flash pasteurization, pasteurization, hot filling, membrane filtration, corking, crown corks, screw closures, Vino Lok closures, level adjustment and control, and labeling.
