Here’s the only exception: if your house is a sauna. Like, you live in a tropical jungle and your kitchen hits 90°F weekly. Then, sure—pop them in the fridge. But even then, bitters are more likely to evaporate slowly than spoil. The real enemy isn’t bacteria; it’s light and heat. Direct sunlight will fade their flavor faster than a bad sunburn. So keep them in a cabinet, behind a bottle of whiskey, or in that drawer you pretend is organized.
I once had a friend who stored her bitters next to the stove. She used them twice, then forgot. When she found them a year later, the liquid had changed color—like a sad, sweet tea. Still safe, still alcoholic, but the orange notes had died. Moral: You don’t need a fridge, but you do need a dark spot. Same vibes as hiding a dusty novel from your judgmental aunt.

The “Expiration Date” Lie
You might see a date on the bottle. Ignore it. That date is for regulatory drift, like the “best by” on salt. Bitters don’t expire; they just get melancholy. Over many years, the alcohol might slowly lose potency, or essential oils degrade. But your grandpa’s bottle of Angostura from 1987? It’s probably fine. Use it, and pretend you’re in a noir film.
In fact, some bartenders swear that aged bitters taste better, like a leather couch that’s learned to sigh. Don’t chuck them out just because a label got bossy. Your taste buds are the real judge, not some corporate calendar.
