Wine Science 1

Abstract

This subject provides an introduction to the principal chemical concepts and analyses that influence wine production, including interactions with microbiology. Students will analyse the key principles behind wine fermentation, composition and stability. Students will develop skills in the general chemical analysis of wine, with an emphasis on safety, fundamental operations of analytical techniques and accuracy in analysis. Students will also become proficient in calculations relevant to wine production. 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 accurately explain the scientific principles involved with winemaking

Be able to analyse winemaking problems and identify actions that will improve them

Be able to safely perform and report on quality control analysis procedures and apply the results

Be able to understand the fundamentals of wine microbiology and winery sanitation

Learning activities

Residential School

The intensive involves:

Skill Development - students will develop skills in specific wine analysis procedures, and consolidate the theory behind the analyses. Students identify these skills to be of high value due to their direct relevance to wine production and/or assessment of grape quality.

Safety - Training in safety requirements for each analysis procedure whilst under supervision. These skills are required for other wine science subjects (i.e. Wine Production 1, Wine Production 2).

Assessment - Completion of the laboratory workbook and laboratory test assess student's practical knowledge of the analyses, the underlying theory, and the calculations associated with the analyses.

Duration4 days

Learning resources

Additional resources required by students

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.
