Okay, so there’s one scenario where you might open the fridge door. If you make your own fruit-based bitters—like a bright, citrus-heavy batch—and you don’t add extra booze? Then maybe refrigerate it. But we’re talking about the store-bought stuff, big brand or small batch.
Commercial bitters are designed to be shelf-stable. The manufacturer assumes you’ll keep them at room temperature. Refrigeration can even be a buzzkill—it might cause tiny particles to settle out or dull the flavor profile slightly.

But Won’t They Go Bad?
This is the cool part: bitters don’t go bad in the way milk does. They can lose potency over ten or twenty years, sure. But “bad” like moldy? Rarely, if ever. The alcohol is too strong a guardian.
Imagine a bottle of soy sauce or balsamic vinegar. Those are fermented, acidic, fine on the shelf. Bitters are even tougher because they’re distilled and boozy. They’re the superheroes of the pantry.
