Learning results

It aims at:

  • Acquiring the knowledge of wine chemical composition, stabilization treatments, conservation, ageing and origins of the main organoleptic defects
  • Understanding and recognizing the relationship among all the above parameters and wine quality
  • The development of their ability to stabilize red and white wines

At the end of the course, students should be able to:

  • Understand the meanings of wine stabilization and treatments
  • Know the chemical composition of wine and its relationship with wine quality
  • Distinguish the main reasons of chemical and microbial instability in wines and make decisions about the possible treatments
  • Connect wine style and ageing
  • Evaluate wine stability using laboratory methods
  • Evaluate wine quality by sensory analysis.
  • Recognize wine defects and their possible origin
  • Make decisions concerning the addition of specific enological substances in wine
  • Work in teams in the lab to complete an analysis, discuss the results and prepare reports
  • Critically compare the results obtained in the lab with published values
