Possibly the most popular brand of bitters, Angostura should be considered a must when stocking a bar of any seriousness. Made with a secret blend of tropical herbs and plants with the original intent of curing a variety of illnesses. The brand is now produced in Trinidad and the blend is still a well-kept secret. The oversized, awkward label has also become a trademark of the brand. It's said that the wrong size was ordered and everyone in the facility thought someone else would fix the mistake, no one did and the label remains.
