Raki (Turkish: rakı ) is an anise-flavored apéritif that is produced by twice distilling either only suma or suma that has been mixed with ethyl alcohol in traditional copper alembics of 5000 lt volume or less with aniseed. It is similar to several kinds of alcoholic beverages available in the Mediterranean and parts of the Balkans, including pastis, sambuca and ouzo. The general consensus is that all these liqueurs preceded arak, a similar arabic liqueur, but it remains a theory.
