Ouzo alcohol at approximately 38% ABV and above, but not in water. Diluting the spirit causes it to separate creating an emulsion, whose fine droplets scatter the light. This process is called louching, and is also found while preparing absinthe. Similar aperitifs include oghi (from Armenia), mastika from Bulgaria and Macedonia, rakı from Turkey, pastis (France), and arak (from the Levant). Its aniseed flavour is also similar to the anise-flavoured liqueurs of sambuca (Italy) and anís (Spain) and the stronger spirits of absinthe (France and Switzerland).

But most producers combine the "ouzo yeast" with less expensive ethyl alcohol flavored with 0.05 percent natural anethole, before water dilution. Greek law dictates that in this case the ouzo yeast cannot be less than 20 percent of the final product. Sugar may be added before water dilution, which is done mostly with ouzo from Southern Greece. The final ABV is usually between 37.5 and 50
