This practical course provides students with the opportunity to gain hands on winemaking experience that expands on areas of fermentation technology and preparation of wine for bottling post vintage. The course introduces students to the planning and managing of winemaking strategies, and importantly complements the theory covered in the other wine technology courses for table wine production. Another objective of this course is to help students make a considerable progression in the development of their wine sensory evaluation skills
Course Coordinator: Associate Professor Paul GrbinCourse Coordinator: Stephen Clarke
Lecturers assisting: Assoc. Prof. Paul Grbin, Assoc. Prof. Chris Ford, Assoc. Prof. Sue Bastian, Dr Richard Muhlack.
The full timetable of all activities for this course can be accessed from Course Planner.Please note that the timetable is subject to change during the semester; this occurs principally to allow flexibility around the white winemaking operations. Students will be informed by email via MyUni of all changes to scheduled events
The course has been allocated time blocks outside the regular timetable each week. This is to ensure that sufficient time is available to undertake the often time-
consuming winemaking procedures. Furthermore, this permits some flexibility for students to negotiate additional time periods with the academic staff or to allow for lengthy periods of cellar/laboratory work and emergency/priority winemaking operations to ensure wine quality is not compromised.
Course Learning OutcomesOn successful completion of this course students should be able to:
1 Identify the processes involved in white winemaking 2 Demonstrate sensory evaluation skills for white wine, beer and cider 3 Plan, manage and evaluate a winemaking strategy 4 Produce and critically evaluate a white wine 5 Apply theories learnt and reflect these in their own white winemaking experiences 6 Critically assess the production of selected wines and/or regions (PG students only)

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 RequirementsTo successfully complete the course the student must demonstrate attendance at all practical sessions shown in the practical program.
Assessment DetailWhite winemaking proposal (0%)
White winemaking proposal – group work. The first part is a presentation to be made as a group in week 2. You will be given feedback on the feasibility of your proposed wine, with suggestions offered by the academic staff to enhance your winemaking project. This formative feedback will include improvements related to your presentation, to support the final presentation.
Sensory Practical Skills (15%)
Working in groups of 4 students, each group will be provided with a wine to evaluate. The group will be asked to answer a series of quiz questions related to their sensory evaluation of the wine style and wine quality. Based on the feedback from this quiz each group will then be required to prepare a brief wine review (video or written). This review will describe the wine style and assess critical quality parameters.
Reflective Diary, Winemaking and Analysis Records (30%)
The Reflective Diary record of winemaking activities should include observations and comments pertaining to the operations in which you are involved. This record of winemaking activities can be written in point form but should describe important winemaking processes in detail and in the correct order of their execution. For example, all major unit process steps such as fermentation, racking, all fining trials and subsequent additions made to wines should include quantities of reagents used and calculations to justify addition rates. If a particular process is repeated during the vintage it can be recorded in detail on the first occasion using a date or process code and simply be referred to on subsequent occasions with any variations noted. However, when a deliberate variation to a unit process or operation is made, it is important that this variation is described in detail and justified. It is important that the logic behind and the rationale for the winemaking techniques and processes be explained and reflected on; for example, how is exposure to oxygen minimised in the transfer of white wine? All laboratory records, calculation, and regular sensory evaluations must be included. A final sensory evaluation and full analytical profile of the student’s wine must be included at Week 12 of semester. Diaries will also be submitted at Week 7 for formative feedback on the students’ progress. Additionally, tasting notes and information from the weekly Sensory Evaluation classes must be recorded in the personal diaries. Each Student Winemaking Groups will be assessed based on the quality, accuracy and consistency of their analytical data and record keeping using the University’s Electronic Winery Data Management Software, this will be included as a 5% component of the Reflective Diary.
Final wine outcome and presentation (10%)
This will be in the form of a presentation to be made in week 12, at which you will describe your winemaking intentions, activities and outcomes and, most importantly, demonstrate a high degree of understanding of the outcomes achieved. The wine made during the seminar will be presented and peer assessed by the class.
Marks will be allocated for this Assignment in the following way: (i). Up to 2.5 for your individual contribution to the group presentation, principally based on the evidence of an understanding of the outcomes achieved for your chosen wine style. (ii). Up to 5 for the overall quality of the group presentation, including a detailed understanding of the winemaking choices selected to achieve the desired outcome, and demonstrated awareness of alternatives and potential solutions to any difficulties that were experienced. (iii). Up to 2.5 for the class evaluation of your wine, based on the final wine quality and its proximity, or otherwise, to the style originally selected.
Wine Style Analysis (PG version only) (10%)
Based on student’s knowledge of white wine and working in conjunction with academic staff, a student will select a white wine style or region and perform an analysis of viticultural requirements, production techniques and typical sensory characteristics unique to that wine style or region. This analysis will be presented in the form of a written report.
Final Exam (35%)
A 2-hour final summative exam will be given at the end of the semester to ensure cumulative knowledge of all course material (lectures, and practicals).
If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
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.

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.
