WSC312 Wine Science 2 (8)
Abstract| Wine Science 2 provides a study of advanced chemistry applications to wine production. The wine chemistry component of the course covers the broad areas of flavour compounds and phenolic chemistry. The latter area includes wine phenolic types, anthocyanin structure and reactivity, phenolic compounds and red wine colour, wine oxidation, barrel maturation, red wine ageing and stability. The analysis of phenolic compounds and red wine colour is covered in the practical component of the subject. |

Learning OutcomesUpon successful completion of this subject, students should:
- Be able to demonstrate the diversity of structure and origin and the challenge of identification of flavour compounds in wine;
- be able to demonstrate the use of chemical principles of bonding, stability, reactivity and reaction mechanism to understand the behaviour of phenolic compounds;
- be able to acurately recognise types of wine phenolic components and interpret their occurrence in terms of grape extraction during winemaking, subsequent modification through ageing and oxidation, and influences of wood treatment;
- be able to evaluate winemaking practices in terms of their effect at a molecular level on wine phenolic composition and identify links between this composition and wine quality;
- be able to perform instrumental quality control and analytical procedures to assess phenolic characteristics in red wines. |

SyllabusThe subject will cover the following topics:
- Wine flavour compounds: monoterpenes, methoxypyrazines, hexenals, alcohols, carboxylic acids and esters. The influence of ageing. Analysis of flavour compounds;
- Chemical principles of bonding, stability, aromaticity and reaction mechanism, and their application to phenolic compound structure and chemical behaviour;
- Types of phenolic compound; anthocyanin structure and reactivity towards water and hydrogen sulfite ion; the pH-dependency of anthocyanin structure;
- Polymeric pigments; mechanisms of polymerisation; ageing; influence of oxidation |

Residential School| This subject contains a compulsory 4 day residential school.
The four-day residential school is compulsory. It requires laboratory analysis. It will also present tutorial sessions that focus on development of an understanding of the subjects fundamental chemical concepts.
