According to an antique tradition, all the countries of the Mediterranean basin have an anise based national liqueur. Italy has Sambuca. It is a sweet and strong liqueur, containing essential oils obtained by steam distilling the seeds of star anise, which are soluble in pure alcohol. A concentrated solution of sugar and other natural aromas are added to this.
Above all, the oils obtained from anise were used by liqueur firms to produce a selection of liqueurs such as: French Pastis, Spanish Anis, Turkish Raki and Greek Ouzo.
