WSC216 Sensory Science (8)

This subject will introduce students to the key principles behind the physiology and characteristics of the senses, with a particular focus on wine sensory assessment. Through the application and development of various sensory testing skills and procedures, students will learn to describe and identify sensations produced by major wine components, main wine varieties, styles, Australian regions and common faults.

This subject commences in session 1 and concludes in session 2. Students must enrol in both sessions 1 and 2. It is not possible to commence this subject in session 2.

Learning Outcomes

Upon successful completion of this subject, students should:
  • Be able to explain the physiology of the perception of taste, smell, and texture, chemesthesis and its impact on sample perception characteristics.
  • Be able to describe sensory testing methods and interpret sensory data.
  • Be able to apply sensory principles to wine and grape juice evaluation, to identify the important sensory characteristics and their balance.
  • Be able to discuss the nature and balance of the sensory characteristics in wines and relate those features to wine type, grape variety, wine style and wine processing.
  • Be able to distinguish between wine faults, and explain their causes.


This subject will cover the following topics:
  • The senses: contrasts of capabilities and physiology; the roles of flavour, odour, taste, texture and appearance.
  • The senses of taste and smell: the sensations, receptors, and their characteristics and interaction, nasal and retronasal pathways, odorant-structure relationships, adaptation, hunger and ageing.
  • Texture: texture types, texture terms and perceptions.
  • Chemesthesis: receptor types, sensation types, sensitisation and adaptation.
  • Appearance: principles of colour vision; attributes of appearance;
  • Sensory assessment: analytic vs hedonic assessment, the role of training, principles of sensory response behaviour, the role of statistics, control of the sensory testing environment.
  • Sensory testing: difference tests, measurement of sensory thresholds, scaling and ranking.
  • Application of sensory principles to wine assessment, the basic tastes, taste interactions, influence of ethanol content, comparison of major wine types, bitterness and astringency, sensory thresholds, influence of wine pH and ageing.
  • Role of odour: interaction of taste and smell, influence of grape variety, introduction to regional effects.
  • Introduction to wine judging, the Australian wine show system, judging wines.

Residential School

This subject contains a 4 day Compulsory Residential School.

The Residential School will allow students to conduct a series of tutored tastings facilitating discussion and providing practical examples that help emphasise key subject outcomes. Those tutored tastings will enable students to identify substances that influence key tastes, experience all wine styles and major varieties, practice threshold levels, identify wine faults and practice judging.

Special Resources

This subject has a residential school. Students will need to cover the cost of travel to campus and accommodation on campus. All students are required to have a lab coat, safety glasses and covered footwear for lab based practicals.
