Expiration & Storage Tips
When does angostura bitters expire?
Angostura Bitters doesn't really go bad, and it lasts indefinitely if properly stored. Unopened, it can last for many years stored in a cool, dry place. Once you've opened the bottle, the bitters can evaporate over time, losing some volume and potency, but it should still be safe and flavorful for a long time, essentially several years.
How do you tell if angostura bitters is bad?
Since Angostura Bitters is a high-proof spirit, it doesn't spoil in a conventional sense. But if it's been stored improperly or the seal has been compromised, allowing air or contaminants into the bottle, the flavor might be off. Check for any unusual smells or changes in color — these could indicate that the bitters are no longer good to use. The most reliable way to test its quality is by using your taste buds. If the product tastes flat or loses its potent complexity, it may be time to replace it.
Tips for storing angostura bitters to extend shelf life
• Store the bottle of Angostura Bitters in a cool, dry place, away from direct sunlight.
• Make sure the cap is tightly sealed after each use to prevent evaporation and maintain its potency.
• Freezing isn't necessary or recommended. Due to its high alcohol content, the bitters remain best at room temperature.
• Although it can be tempting, don't decant or transfer the bitters into a different container. The original bottle is designed to preserve the quality and flavor.
