Absinthe
A high-strength spirit built on wormwood, green anise and fennel, bottled anywhere from 45% to 74% alcohol. It is used in drops and rinses rather than in measures, and its reputation for driving people mad has almost nothing behind it.

Storage & Handling
Store upright in a cool, dark place away from direct sunlight. Reseal tightly after use to prevent evaporation of volatile aromatics.
Shelf Life
Indefinite when stored sealed and upright
Usage
A few millilitres swirled round a chilled glass and tipped out, which is how the Sazerac and the Corpse Reviver No. 2 use it. Where it is measured at all it is measured in dashes, because it will take over a drink at anything past 5ml.
Wormwood, Anise, Fennel
Three plants define the spirit, and producers call them the holy trinity. Wormwood, Artemisia absinthium, gives the bitterness and the name. Green anise gives the aniseed weight that most people taste first. Fennel rounds the two together. A traditional production distils a macerate of those and then steeps further herbs in the clear distillate, which is where the green colour comes from: chlorophyll drawn out of hyssop, melissa and more wormwood. That colour fades towards amber with age and light, which is why old bottles look brown, and why a bright emerald absinthe has usually been coloured artificially rather than by plants.
The Thujone Myth
Absinthe spent most of the twentieth century banned on the strength of a claim that has not survived examination. Thujone, a compound found in wormwood, was said to cause hallucinations and madness, and the drink was outlawed in France in 1915 and in the United States in 1912. Later analysis of sealed pre-ban bottles found thujone at levels within what modern regulation permits, which is 35 milligrams per kilogram for a spirit of this kind. The likelier explanation for what happened to absinthe drinkers is that they were drinking something near 70% alcohol, in quantity, daily. The bans were lifted in the United States in 2007 and in France in 2011.
The Louche
Adding water to absinthe turns it cloudy, and the effect has a straightforward explanation. Anethole, the aromatic compound from the anise, dissolves readily in alcohol and barely at all in water. Diluting the spirit drops the alcohol below the level that can hold it, so the anethole comes out of solution as a fine suspension and the drink goes milky. That is the louche, and it is a fair indicator of a spirit flavoured by distillation rather than by additives, since a coloured, essence-based absinthe often will not do it properly. Traditional service pours three to five parts iced water slowly over a sugar cube on a slotted spoon.
Using It in a Drink
The rinse is the standard technique: a few millilitres poured into a chilled glass, swirled to coat the inside, and the excess discarded. What remains is aroma rather than flavour, and it arrives before the first sip in the way a citrus oil does. The Sazerac and the Corpse Reviver No. 2 are both built that way. Death in the Afternoon goes further and measures it properly, absinthe lengthened with champagne, on Hemingway’s own instruction. Pastis is not the same thing and is often substituted for it: anise without wormwood, sweeter and weaker, reading as softer wherever it stands in.
Pro Tip
If you can taste absinthe clearly, you’ve already used too much.
Top Tips
- Rinse and discard. What stays in the glass is the whole point, and what pours out was never needed.
- Add water slowly to a neat pour. The louche builds as the anethole comes out of solution, and rushing it gives a flat drink.
- Substitute pastis knowingly. It has the anise but no wormwood, and it is sweeter and weaker than the recipe assumed.
Possible Substitutions
- Absinthe pastis (less bitter, more anise)
Production Method
Produced by distilling alcohol with herbs including wormwood, anise, and fennel, followed by optional colouring with additional botanicals. Traditional methods emphasise clarity and balance.
History & Context
Absinthe rose to prominence in 19th-century Europe before being banned in many countries due to moral panic and misinformation. Its revival restored its place as a defining aromatic accent in classic cocktails like the Sazerac.
Common Questions
Is absinthe hallucinogenic?
No. The claim rests on thujone, a compound in wormwood, and analysis of sealed pre-ban bottles found it at levels within what regulation permits today. What harmed absinthe drinkers in 1900 was drinking a spirit near 70% alcohol daily and in quantity. The bans have since been lifted.
What is an absinthe rinse?
A few millilitres poured into a chilled glass, swirled until the inside is coated, and the excess tipped away. It leaves aroma without measurable volume, which is exactly what a Sazerac wants: the anise reaches the nose before the whiskey reaches the tongue.
How strong is absinthe?
Usually between 45% and 74% alcohol, which is why it is served diluted and used in drops. The strength is functional rather than a boast, because the anethole and the other aromatics need that much alcohol to stay in solution in the bottle.
What does absinthe taste like?
Aniseed first, then a green bitterness underneath it from the wormwood, and a cooling quality from the fennel. Neat it is fierce and not much use. Diluted, it opens out into something herbal and rounded, which is the form it was designed to be drunk in.
