Pernod is made from the essence of star anise, a tree-growing fruit from North Vietnam and southern China. The ethanol that is extracted from this essential oil is mixed with the essential oils distilled from other herbs and spices.

Pernod's secret formula includes mint, added for its cooling and digestive properties, and coriander, for its intoxicating, subtle flavor.

Pernod is different from other anise-based spirits as its flavor and subtle bouquet come from the distillation of star anise.

Pastis, on the other hand, is produced by steeping and includes licorice as one of the main flavoring agents.
