What is one major difference between Pastis and Absinthe?

One major difference between Pastis and Absinthe is that Absinthe must be made using wormwood. Wormwood is a key ingredient in Absinthe and contributes to its distinct flavor and bitterness, as well as its historical reputation. This herbal component is what primarily differentiates Absinthe from Pastis.

Pastis, on the other hand, does not necessarily contain wormwood and is often flavored with other botanicals and anise, leading to a different taste profile. While both spirits are known for their anise flavors, wormwood is a defining characteristic of Absinthe, making it essential for its identity. Thus, the presence of wormwood in Absinthe illustrates its unique qualities compared to Pastis.
