Why You Shouldn’t Store Coffee in the Fridge?

Some habits stick around for decades, even if they don’t actually make sense. One of the most common tips you’ll still hear—especially in the U.S. and Europe—is:
 “Keep your coffee in the fridge so it stays fresh.”

It sounds reasonable. Cold equals fresh… right?

Not when it comes to coffee.

Even though a fridge feels cold and “dry,” inside it’s actually a pretty humid environment. Modern refrigerators constantly cycle air through cooling and defrost phases, which creates tiny shifts in temperature and humidity.

And every time you open the door, warm air from the kitchen sneaks in, cools down fast, and condenses on anything cold—including your coffee bag. Add to that the moisture released by fruits, veggies, and leftovers inside, and you end up with a surprisingly damp environment.

When you pull a cold bag of coffee out of the fridge, tiny water droplets form inside and outside the packaging. Those droplets speed up oxidation, dull your coffee’s flavor, and mess with the delicate oils and aromas that give good coffee its character.

If the bag isn’t perfectly sealed, that moisture can even lead to mold or funky off-flavors over time. Scientific studies have shown that roasted coffee is highly hygroscopic (it absorbs water quickly), and that even small changes in moisture content can accelerate aroma loss and oxidation.

Coffee is porous—it soaks up whatever’s around it. In a fridge with onions, cheese, or yesterday’s leftovers, your beans will start picking up those smells fast. And trust us, onion-latte is not a thing you want to invent.

Here’s what actually works:

That’s it. No fridge needed. Just a good bag and a smart spot in your kitchen.

All of our Cafecito Power bags are made with four protective layers, developed specifically for specialty coffee. They include:

These are not generic food pouches — they’re coffee-specific bags, built to keep your beans fresh at room temperature, without the need for refrigeration.

Refrigerating coffee is an old habit that made sense when people bought giant tins of pre-ground coffee once a month. But if you care about flavor, it’s time to retire that trick.

Keep your beans protected from moisture, odors, and temperature swings, and they’ll return the favor in your cup every morning.

Because the fridge is for leftovers, not coffee. ☕

TL;DR → Fridge = humidity, condensation & lost aroma.

Proper bag + cool, dry storage = freshness
