OENOLOGY 2502WT - Sensory Studies II

Waite Campus - Semester 2 - 2024

This course provides a scientifically based introduction to sensory evaluation and its relationship to the winemaking process, and promotes the development of technically accurate wine assessment skills. The physiology of taste receptors, olfaction and the structure of oral mucosa are examined. Recent advances in knowledge including the function of signal transduction molecules and protein structure are used to explain current models of flavour, astringency and taste perception. Basic flavour chemistry of grapes and wine and wine faults is introduced. An introduction to sensory measurement theory, psychophysics, aroma and taste interactions, threshold measurement and the psychological and physiological factors affecting perception is presented. The concept of adaptation and its application to the sensory evaluation of wines, and elements of good sensory practice including data collection and statistical analysis are described. The practical program will be used to develop basic skills in sensory assessment of wines leading to the interpretation of wine characteristics in terms of wine style and quality. This is achieved by a progressive development of sensory skills, using model solutions to depict basic tastes and their interactions, followed by detailed examination of white and red table, fortified and sparkling wines, and wine and food interactions.

Online Learning

Student's will be advised of online learning materials via MyUni throughout the semester.

Learning & Teaching Modes

Lectures are supported by online material, readings and practical exercises designed to highlight theoretical concepts that build student’s knowledge in the areas of sensory science, psychophysics and psychographics, oenology, wine flavour chemistry, human physiology and biology and formal and informal sensory evaluation of wines. The group-discussion based learning approach in the practicals help to develop student knowledge and application of that knowledge to unknown wines samples to permit them to accurately describe wines to others in a technical manner at industry expected standard. Further, the practicals aim to profile student’s individual sensory acuity and ability for personal awareness and development.

Workload

The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., assignments, reading and revision).

Assessment Related Requirements

Pass requirement
To successfully complete the course, the student must gain at least 50% for the practical write up and sensory tasting exam components and produce an overall mark of at least 50% of the combined marks for all assessment components. There is no replacement/additional assessment available for the practical component of the course. If a student does not meet the requirement of 50% of the available marks for this component they will fail the course. In addition, at least 50% for the final written examination must be obtained. All assignments are compulsory. Students who do not attempt and submit all assignments will fail the course. All practical classes are compulsory. Failure to attend any practical sessions shown in the practical programme without a medical certificate or prior agreement with the course co-ordinator may result in the student failing the course.

Assessment Detail

Practical Write Up
All students will be required to conduct a number of different testing methods in practical class and then write up the class data in the format of short reports. More information will be given during the practical classes.

Tasting Exams
Tasting exams will be conducted in the practical sessions. All students need to attend unless they are unable to on the basis of medical or compassionate grounds. A medical certificate or note from a qualified practitioner is required as proof of an existing condition of the day of the exam. If this is the case the student needs to contact and make other arrangements with the course coordinator to sit the exam at a later date.

Tasting Evaluations in Practical Classes
All students are expected to contribute to class discussion in practical classes. Grades will be given for attendance and comments made by each student on wines on a random basis over the semester.

Final written examinations
Course content changes slightly from year to year however questions that have been set in previous examinations are available and in the majority are still relevant. All lecture material and practical session information is examinable.

Submission

A hard copy of the practical write up is required. The lecturer will provide more details for submission during the semster.

Course Grading

Grades for your performance in this course will be awarded in accordance with the following scheme:

Student Feedback

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Fraud Awareness

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
