Ouzo is an aniseed-flavoured spirit produced in Greece, traditionally made by distilling neutral spirit with aniseed and often other botanicals such as fennel, mastic, and coriander. Usually drunk mixed with water or accompanied by water, it displays the famous louche effect: dilution turns the clear spirit milky white as the anise oils come out of solution. Typically bottled around 40 percent alcohol by volume, ouzo holds protected geographical indication status within the European Union, meaning authentic ouzo must be made in Greece. It is served as an aperitif alongside meze, and its production is regulated for methanol limits and labelling, like other distilled spirits.
