So, do bitters go bad if not refrigerated? The answer is, it depends. Some bitters can last for years if stored properly in a cool, dark place, while others might lose their potency and flavor over time. It's similar to how a good wine can age beautifully, but a cheap one might turn into vinegar if not stored correctly.
Now, you might be thinking: but why bother with refrigeration if bitters are already preserved with a high alcohol content? Well, the thing is, while the alcohol does act as a preservative, it's not enough to completely prevent oxidation and spoilage. Think of it like a bottle of fine whiskey - just because it's got a high alcohol content doesn't mean it won't benefit from being stored in a cool, dark place.
