Angostura Bitters
There is no angostura bark in Angostura bitters. The name belongs to the Venezuelan town where Dr Johann Siegert blended the recipe in 1824, the bitterness comes from gentian root, and everything past that is held by a handful of people.

Angostura Aromatic Bitters: one producer, one recipe, and a bottle outlasts most of the spirits beside it
Storage & Handling
Store sealed at room temperature away from direct sunlight. Shelf stability is extremely high due to alcohol content and concentration.
Shelf Life
Indefinite when stored sealed at room temperature
Usage
Two dashes in an Old Fashioned, one in a Manhattan, and a dash across the foam of a sour where the aroma does the work. It is seasoning rather than an ingredient, measured in dashes and never in millilitres.
The Name Is a Red Herring
Angostura bitters contain no angostura bark. The name comes from the town of Angostura on the Orinoco, itself named for the narrows in the river, where Dr Johann Siegert was working as a surgeon and blended the recipe in 1824. He called it Amargo Aromatico.
The bitterness is gentian root, a traditional digestive bitter, carried on a long list of botanicals nobody outside the company has seen in full. The secrecy is genuine rather than marketing: the recipe is known to very few people and has stayed that way for two centuries.
Why Dashes and Not Measures
The bottle runs at 44.7%, and the concentration is the reason a recipe never asks for millilitres. A dash is somewhere near a millilitre from a consistent dasher and something else entirely from the factory top, which is why any drink built on a dash count is worth decanting for.
At those quantities the alcohol contributed to the finished drink is negligible. It is also why an opened bottle keeps for years without fading: there is nothing in it for spoilage to work on.
What It Actually Does
Bitters season rather than embitter. Two dashes in an Old Fashioned bind the sugar to the whiskey, add spice depth through the middle and dry the finish out, and none of that reads as bitterness on the palate.
The test is subtraction. A drink built without its bitters does not taste less bitter, it tastes flabby: the sweetness sits apart from the spirit with nothing holding the two together, and the finish runs long and sugary rather than closing cleanly.
Keeping It
Sealed, upright, at room temperature and out of direct sun, where it will outlast most of the bar. High strength and high concentration make it close to indestructible, so a bottle bought for one recipe will still be good years later.
The oversized label is the other thing everyone notices. It has never fitted the bottle and has never been corrected, which by now is the point of it.
Pro Tip
Think of Angostura as seasoning: it ties flavours together more than it competes with them.
Top Tips
- Decant into a proper dasher bottle if a recipe leans on the count. The factory top pours wildly differently from a dasher, and two dashes stops being a measurement.
- Dash it over foam rather than into it. The aroma arrives before the first sip, which is most of what the bitters are contributing to a sour.
- Do not chase the bitterness. At dash quantities it is binding sugar to spirit, and a drink that tastes bitter of Angostura has had far too much.
Possible Substitutions
- Other aromatic bitters (profile will vary)
- House aromatic bitters (if available)
Production Method
Produced by infusing high-proof spirit with a proprietary blend of herbs, spices, roots, and botanicals. Aged and blended to achieve consistency and concentration.
History & Context
Originally developed in the early 19th century, Angostura Bitters became a cornerstone of classic cocktail culture. Despite its name, it is produced in Trinidad and Tobago and remains one of the most recognisable bitters worldwide.
Common Questions
What is actually in Angostura bitters?
Gentian root carries the bitterness, on a long list of botanicals known in full to a handful of people and unchanged since 1824. What is not in it is angostura bark, despite the name, which comes from the Venezuelan town where the recipe was blended.
How much is a dash of Angostura?
Roughly a millilitre from a consistent dasher bottle and wildly variable from the factory top. When a recipe leans on the count rather than a measure, decant it, because two dashes only means something if the bottle pours the same way twice.
Do bitters make a drink bitter?
Not at dash quantities. They season instead: binding the sugar to the spirit, adding spice depth through the middle and drying the finish. A drink built without its bitters does not taste sweeter so much as flabby, with nothing holding the parts together.
Are Angostura bitters alcoholic?
The bottle runs at 44.7%, which is higher than most spirits, but the quantities used put a negligible amount of alcohol into a finished drink. That strength is also why an opened bottle keeps for years without fading or spoiling.
