No one textbook adequately fulfils the requirements of this course. The currently available texts are all written from a non-Australian perspective, and therefore address only some aspects of what is pertinent to the situation in Australia. The major oenological texts are also expensive, and for this reason it has been decided that where possible the chapters in each of the four texts relevant to each lecture will be indicated by the lecturing staff at the time of delivery. Students are encouraged to take the opportunity during the semester to compare the various texts, 2 copies each of which are held in the Woolhouse (Waite) Library on Reserve, as an aid to deciding which one best suits their personal requirements and preferences.

Copies of the Course Profile (this document) and the Course Handbook (including the Timetable of Lectures, Practicals and Tutorials) will be posted on MyUni. Coursework assignments may be submitted through Turnitin as directed. Coursework marks will be made available through the Gradebook. Assessment in the form of online quizzes will be offered during the semester as a part of the Formative Assessment component. Details may be found below. All materials will be released at the relevant time during the semester.
Learning & Teaching Activities
Learning & Teaching ModesThe course material is taught by a combination of lectures and practical classes, with formative assessment exercises in the form of practical write-ups, a practical test, a written assignment, and online quizzes, and summative assessment in the form of end-of-semester examination. Lecture modes used are based primarily on traditional classroom paradigms of lecturer-student interactions, using PowerPoint or similar presentation techniques. The use of enhanced teaching approaches including student-centred activities is likely to increasingly feature in this aspect of the course. Short online quizzes are provided to allow regular self-assessment of understanding and progress.
Practical classes including a site visit to a local winery are designed and timetabled such that as far as possible, the topics co-ordinate with those being taught at that time within the lecture stream. Learning within practical classes will be based on student participation in a series of experimental exercises designed to demonstrate some of the key grape and wine analytical techniques, yeast culture, and the management of a small-scale (ca 30L) alcoholic fermentation, as a prelude to larger (1,000L) ferments conducted in higher-level courses. In some cases, report writing, including quantitative data analysis and interpretation and problem solving, will form part of the learning activities.
Feedback is provided on all assessed work.
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., reading and revision).

The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

Assessment Related Requirements
Assessment Task Requirement for hurdle Is additional assessment available if student does not meet hurdle requirement Details of additional assessment End of semester examination 50%
Summative (examination-based) Assessment - details:
The final examination will consist of one paper divided into two sections. Section A will comprise questions dealing with calculations used in winemaking. It will be worth approximately 8% of the final paper (15 marks out of 180 total). Section B will comprise questions covering the whole course and be worth approximately 92% of the final paper. Questions will be compulsory although there may be choice within questions.
Formative (coursework) Assessment - details:
Formative assessment for the course will be covered by the following items:There will be eleven practical classes conducted per student over the course of the semester. A written report will be submitted for the outcome of the chemical analyses of wine (pH, titratable acidity, sulfur dioxide and reducing sugar) conducted in weeks 2-4 (5%). A second report will be submitted for the analysis of red wine phenolics conducted in weeks 5 or 6 (the class is divided into two for this exercise). All submitted work will be returned with feedback within 2 weeks of submission.
1. Practical class reports:
2. Practical skills test:
In weeks 7 or 8 students will be assessed on their ability to accurately determine the pH, titratable acidity, total, free and bound sulfur dioxide, and volatile acidity of a wine. They will be required to report their analytical findings in an appropriate manner, and demonstrate their ability to undertake basic wine calculations.
3. Red wine production assignment:
Students will prepare a written proposal for the production of a medium to full-bodied dry red table wine. The exact wine style and source of grapes is the choice of the student. The proposal is to describe every aspect of the winemaking process from the perspective of activities that can be conducted using the facilities available in the Wine Science Laboratory. A flow chart of the processes is to be submitted along with details of the proposed wine style that explain how the winemaking options selected will lead to the selected wine style outcomes. Exemplars from previous students will be available on MyUni.
4. Fermentation management assignment:
Students will work in groups of two or three to undertake the fermentation of a 30-litre batch of white grape juice. The aim of the exercise is to maintain a steady rate of fermentation by the use of appropriate monitoring and temperature control management. You will monitor your ferment twice daily over a seven-day period; each monitoring event will require approximately 15 minutes to complete, each student will conduct between four and five individual monitoring events. Full chemical analyses will be conducted at the outset, at a point mid-way through the fermentation, and upon completion of the fermentation. The assessment is based on an individual report that comprises a fermentation progress curve, indicating the monitoring points, fermentation parameters and the decisions that were made and their subsequent consequences. Exemplars from previous students will be available on MyUni.
5. Online quizzes: During the semester, 5 online quizzes will be set from within MyUni/Assessments. Each quiz will contain 10 questions, which will comprise a number of formats including but not limited to multiple choice, missing words, ordering and calculations. Quizzes will normally be available for a four-day period including weekends, which will be announced via a MyUni Announcement and email to each student.
The quizzes are intended to provide each student with a brief assessment of their knowledge of topics covered in recent and past lectures and tutorials. Each quiz may be attempted only once; students will receive their scores immediately upon completion of the quiz and full feedback after the quiz closes.
Penalty For Late Submission Of Assignments
A signed Assessment Coversheet must accompany all work submitted for assessment during the semester. Copies are available for download from MyUni and are also included in the Practical booklet.
Assignments must be submitted by their deadlines. For work submitted past the deadline for that assignment, there will be a penalty of 10% of the unprejudiced mark for each working day (or part of a working day) that an assignment is late, up to a maximum penalty of 50% of the unprejudiced mark (all eligible submitted work is assessed in the first instance without prejudice). The examiner may elect not to accept any assignment that a student wants to submit after the assignments for the rest of the class have been marked and feedback provided.
Extensions of deadlines may be allowed for reasonable causes. Such situations would include compassionate and medical grounds of the severity that would justify the awarding of a supplementary examination. Evidence for the grounds must be provided when an extension is requested. Extensions of deadlines should be negotiated with the course coordinator before the assignment is due. Extensions will not be provided on the grounds of poor time management.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
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.
