Project description
Increased local and global competition leading to the ever increasing need for improved wine quality, high alcohols unacceptable to consumers and current resistance by consumers to genetically modified products are some of the ongoing problems faced by the South African wine industry. In an effort to address this situation, further utilisation of non-Saccharomyces yeasts needs to be investigated.

The objective of this project is to investigate the potential of Torulaspora delbrueckii yeasts to produce novel wine, wine with lower alcohol concentrations (single and co-inoculations with Saccharomyces cerevisiae), while maintaining or increasing wine quality during production of both red and white wines.
