Angostura aromatic bitters is a concentrated, high-proof bitters built on gentian, with a secret blend of herbs and spices. Its bitterness is warm and spiced.
A dash or two seasons whiskey and rum drinks, from an Old Fashioned to a Manhattan, and ties their flavors together. Dashed over a fizz or a sparkling drink, it adds aroma on top. The big exception is the Trinidad Sour, which uses a full 45 ml and makes the bitters its base.
Angostura-style bitters
Other classic aromatic bitters with a similar flavor work dash for dash. The spiced bitterness stays, only the finer notes change.
Peychaud’s bitters
This famous Creole bitters goes in at the same count. But it is lighter and more floral, pulls the flavor toward anise and tints the drink red.
A weaker fit, since it changes the balance itself. Angostura gives the drink the warmth of dark spices, while orange bitters pulls it toward citrus brightness.
No bitters
In a drink full of other strong ingredients, losing a couple of dashes only simplifies the flavor a little. A strict classic like the Old Fashioned simply does not work without bitters, so Peychaud’s or orange bitters beats nothing.
"Angostura bitters contain angostura bark"
They do not. The name comes from the Venezuelan town of Angostura, now Ciudad Bolívar, where Dr. Siegert created the recipe in 1824.
At 44.7% nothing in the bottle can spoil. The practical problem is the dasher: sugar and extract dry in the neck and crust the opening shut. Rinse the cap under hot water when it starts to drip unevenly.
