The ouzo effect (also louche effect and spontaneous emulsification) is a phenomenon observed when water is added to ouzo and other anise-flavored liqueurs and spirits, such as pastis, raki, arak and absinthe, forming a milky (louche) oil-in-water microemulsion. Because such microemulsions occur with only minimal mixing and are highly stable, the ouzo effect may have commercial applications.
