Expiration & Storage Tips
When does bitters expire?
Unopened, a bottle of bitters can last indefinitely, thanks to its alcohol content. Even after it's been opened, as long as it's stored properly, it won't spoil for several years. The flavors might lose some punch over time, but it won't ever become dangerous to consume. They don't typically require refrigeration or freezing, and though their flavorful intensity might wane after an extremely long period (think: years), it's almost impossible to say that bitters have a traditional 'expiration date'. If you're using them regularly in cocktails or culinary applications, a bottle won't have much of a chance to stick around that long anyway! In case of home-made bitters, the longevity is approximately the same as long as it’s properly sealed and kept in cool and dark place.
How do you tell if bitters is bad?
Bitters tend not to spoil fully due to their alcohol content. However, if your bitters have been stored improperly or for an extremely long period of time, you may notice a slight lessening in flavor intensity. They may not enhance your cocktail or meal as much as they normally would, signaling that it's time for a fresh bottle. They also might develop an off-odor or the color may change more dramatically, these are signs that bitters may have gone bad.
Tips for storing bitters to extend shelf life
• Store bitters in a cool, dark place away from direct sunlight.
• Keep the bottle sealed tightly when not in use.
• It's not necessary to refrigerate or freeze bitters, but try to keep them in steady temperatures.
• Homemade bitters should be stored in airtight glass jars or bottles and kept in a dark cabinet.
• Remember, while the flavors may lessen over time, it doesn't mean the bitters have spoiled, so don't be too quick to toss them!
