The Singapore Supreme Court has rejected an appeal from Australian producers of Prosecco wine, allowing Italian producers to register "Prosecco" as a geographical indication belonging only to the Italian region. Geographical indications link a food or drink to the specific region where it is produced, ensuring that consumers can identify products with their regional characteristics. The court ruled that the Australian producers failed to provide sufficient evidence to suggest that consumers would be misled by the geographical indication "Prosecco."
