Prerequisite(s):
(BIO115 or BIO118 or MCR101 ) and (BCM210 or BCM206 ) and WSC101
Objectives:
Upon successful completion of this subject, students should:
be able to demonstrate an understanding of the physiology and biochemistry of the alcoholic fermentation by wine yeasts;
be able to demonstrate an understanding of the physiology and biochemistry of the malolactic fermentation;
be able to demonstrate an understanding of the ecology and biochemistry of wine spoilage by microorganisms; and
be able to demonstrate an understanding of control of microorganisms during winemaking;
be able to demonstrate an understanding of the basic techniques used in the study of wine microorganisms.
Syllabus:
The subject will cover the following topics:
- Ecological aspects of the alcoholic fermentation : species of yeasts active during wine fermentations; factors affecting their growth and metabolism; - Biochemistry of flavour and aroma production by yeasts during the alcoholic fermentation; - Bacterial ecology of the malolactic fermentation : interplay of bacterial species during the malolactic fermentation; impact of wine environment on bacteria during this process; modifications to wine flavour and aroma resulting from the malolactic fermentation; - Role of yeasts and bacteria in spoilage reactions : ecology of spoilage activity; flavour and aroma modifications during spoilage by various microorganisms; control of spoilage microorganisms, and - Control of microorganisms during winemaking : chemical additions to wines; impact of variations in processing technique.
Residential School
