National Absinthe Day
National Absinthe Day is observed every year on March 5.
Absinthe is a high-proof, unsweetened distilled spirit flavored with botanicals like wormwood, anise, and fennel. It often tastes herbal + licorice-like, and it’s usually diluted with water before sipping.
Interesting Fact: When you add cold water, aromatic oils (especially anise-style compounds) fall out of solution and create that signature milky glow, called the louche.

What This Day is About
National Absinthe Day is a nod to absinthe’s myth-heavy legacy- the emerald spirit nicknamed “the Green Fairy” and to its place in cafe culture, art history, and modern cocktails. In the U.S., March 5 is often linked to absinthe’s modern comeback, because it’s commonly referenced as the date the long-era prohibition effectively ended and legal sales resumed under strict thujone rules.
The Interesting History of Absinthe
Late 1700s
Absinthe’s precise start is debated, but many accounts place its early rise in Couvet, Switzerland, in the late 18th century often tied to Dr. Pierre Ordinaire and early commercial production by Dubied/Pernod.
The Paris boom + 'Green Hour'
By the 1800s, absinthe became a cultural ritual in France. 5 p.m. at cafés became known as l’heure verte (“the green hour”), when people gathered specifically for absinthe.
Panic, politics, and bans (early 1900s)
Absinthe got blamed for social disorder and “madness,” and bans rolled across countries. One frequently cited flashpoint was the 1905 Lanfray case in Switzerland widely publicized as the “absinthe murders,” even though reports show he drank a lot more than absinthe that day.
The myth that wouldn’t die: “Absinthe makes you hallucinate”
A major villain in the myth is thujone, a compound from wormwood. But modern analysis of vintage pre-ban bottles found thujone levels that don’t match the old scare-story exaggerations.
The modern comeback (with rules)
Today, absinthe is legal in many places but regulated. In the U.S., regulators treat “thujone-free” as below 10 ppm, and labeling/approval follows federal policy.
Celebrate National Absinthe Day
Remember this is for legal drinking-age adults only and keep it moderate. Absinthe is strong.
Do the classic French drip ritual
This is the iconic preparation:
- Pour a measure of absinthe into a glass
- Rest a slotted absinthe spoon on top
- Place a sugar cube on the spoon
- Slowly drip ice-cold water over it until diluted (often ~3:1 to 5:1 water to absinthe)
Watch the louche like it’s a tiny science show
Add cold water slowly and you’ll see the drink turn opalescent. That louche happens because the botanical oils behave differently as alcohol concentration drops.
Try absinthe the “cocktail way”
Absinthe is powerful, so many people enjoy it as a rinse or accent in cocktails (it changes a drink fast, even in small amounts). A classic example is the Sazerac, traditionally using an absinthe rinse.
