The ban needs to be enacted legislatively after market creation.
What counts:
- ban on distilled spirits only 
- ban for people born after a given date (simmilar to NZ tobacco ban) 
- extremely restrictive personal quotas (<20% average consumption prior to enactment) 
What does not:
- increasing drinking age 
- restricting sales to a small number of outlets 
- supreme court decision finding the sale of alcohol unconstitutional 
- anything a country with a theologically driven legislature does 
- an attempted ban that gets legally overturned before coming into effect
