What is the primary flavoring agent of absinthe?

The primary flavoring agent of absinthe is wormwood. This aromatic herb, specifically its species Artemisia absinthium, is essential to absinthe’s distinctive flavor profile and is one of the key ingredients in its production. Wormwood contributes to the drink’s bitter and herbal characteristics, which are crucial to its identity.

While anise and fennel are also commonly included in absinthe recipes and impart their own unique flavors, it is the wormwood that is most often associated with absinthe's traditional and historical significance, particularly in relation to its reputation and the lore surrounding the spirit. Juniper, on the other hand, is primarily associated with gin, while mint does not play a significant role in absinthe's flavoring. Thus, wormwood stands out as the definitive and primary flavoring agent in absinthe.
