How to store your coffee

Author: Bliss Coffee Roasters  

One of the most common questions we get - "how should I store my coffee?"

Before you drink it, the coffee cherry goes through many processes from it first growing on a tree to being washed, dried, shipped across the globe, carefully roasted, de-gassed, packaged and delivered to you. That roasted coffee is still a fresh product so it’s always changing, and like all fresh products it’ll slowly degrade over time.

As a guide, our coffee tastes best when brewed 5–28 days after roasting

Because we roast in small batches, more often, when you order with Bliss, you’ll be receiving product at its freshest and best. Coffee beans, within the first few days after roasting, are too fresh: the aromas and flavours are still developing and aren’t at their brightest. After 28 days, those flavours start to fade away again, giving you a more muted cup of coffee.

Once you’ve opened your bag of Bliss coffee beans, here’s some tips to help you best store them for maximum flavour and lifespan.

Use an airtight container

All our beans are packed in resealable bags, which are designed to keep the air around the coffee sealed so it doesn’t get exposed to fresh air and oxidise quickly. When resealing your coffee bag, squeeze out any air before sealing it. 

If you’d prefer, you can transfer the beans to a small, opaque, airtight container (like an AirScape available here). After 2-3 days, most of the gases from the coffee beans will have been released escaped the bag we packed the coffee into via the one-way valve.

Grind on demand 

It’s the oils and moisture in the coffee bean that gives you a delicious cup of coffee: but they both also react with air over time. That’s why we recommend grinding your coffee just before you brew, so all that flavour goes into your cup, not into the air.

Cool, dark place.

Once you’re storing the coffee in an airtight container, the other two things that can negatively impact the quality: exposure to light, and heat. The good news is, they’re both an easy fix! Store your coffee in a cool, dark, dry place (but not the fridge) that is away from sources of heat or steam like kettles, stoves or an espresso machine. The pantry generally works perfectly. Airscape features a black middle lid, preventing any light coming through to the beans. This makes them perfect to keep out on the bench, on display if you wish. 

Why not the fridge?

Ground coffee and coffee beans naturally attract moisture, so as soon as you take those beans out of the fridge, they will start to condensate and will start to sweat.

Not only do sweaty beans not sound great, they don’t taste great either. What flavour is left in the beans that haven’t been sweated out, will have also absorbed the aroma of whatever has been in your fridge. So, if you had say, left over fish, last nights lasagne, some not so fresh fruit at the back of the fridge, you’ll now experience those flavours in your coffee (yuck!).

On a rather serious health note – moisture affected beans could also be a significant health hazard as it can cause mould to grow. If you have stored your beans in the fridge or freezer, look over the beans before you use them, if you’re still game.

 

Don’t freeze your coffee

You’ve probably heard about storing coffee in the freezer, and while it’s possible, we generally don’t recommend it.

Freezers are great at sucking moisture out of the air to help preserve foods. When we roast coffee, there’s a very carefully controlled amount of moisture left at the end: freezing beans can interfere with this, giving you flat, stale-tasting coffee. As the frozen beans defrost, the moisture that’s reintroduced condenses on the beans and dilutes the flavour. Frozen, and defrosted roasted coffee will also cause the coffee oils to congeal.

For these reasons, we advise against freezing beans: or if you do, to only freeze and defrost whole coffee beans once, but be aware you risk the same condensation issue mentioned above with beans stored in the fridge.
