Learning Goals
This UC intends to give an overview of the processes, both physical and chemical, involved in the clarification and stabilization of wines. Students should acquire knowledge on post-winemaking technologies and the impact of each option on the characteristics of wines
At the end of the UC students should be able to plan and execute the treatments necessary to obtain a quality wine, stable and clarified.
