Pink Gin (a few drops of bitters to coat the inside of a glass, with gin poured in straight on the top), Whisky Cocktail (bitters, sugar and lime juice muddled together, with ice cubes on top and your favourite whisky) and a Bourbon Lancer (Angostura Bitters, bourbon, champagne mixed and served on ice) are just three of hundreds of cocktails that just don’t work without Angostura Bitters.
Angostura bitters is a concentrated bitters, or botanically infused alcoholic mixture, made of water, 44.7% ethanol, gentian, herbs and spices, by House of Angostura in Trinidad and Tobago. It is typically used for flavouring beverages or (less often) food. The bitters were first produced in the town of Angostura (Ciudad Bolívar, Venezuela) (hence the name), and do not contain angostura bark. The bottle is easily recognisable by its distinctive oversized label.
