How to store your coffee?

Contrary to popular belief, coffee is a sensitive product and acts like a sponge. It should not be overly rough, or it may lose its natural qualities and those developed during roasting.

Enemies of coffee - nm

  • Axe drawing
    Oxygen , a source of oxidation responsible for the loss of oils and therefore of aromas.
  • Extreme temperatures , and especially significant temperature changes causing thermal shock, thus degrading the aromas. Therefore, do not store your coffee near a radiator or oven.
  • Light , although less aggressive for coffee than oxygen, is able to degrade your coffee in a few days.
  • Humidity: Make sure that the environment where you store your coffee is not too humid.

So you can see why you shouldn't fill the reservoir (or hopper) of a grinder or coffee machine with an integrated grinder, as tempting as it may be.

Protections - nf

To optimize the protection of coffee against these factors, there are two complementary solutions:

  • Winged helmet drawing
    Original packaging: At Celsius, we protect the coffee in a completely airtight bag, with a degassing valve so that the fresh coffee can get rid of excess CO2, without letting in ambient air, which would contribute to premature oxidation. The bags can be resealable hermetically thanks to the zip.
  • An airtight container : When the coffee has released the excess CO2 in the original packaging after a few days, it is a good idea to use an airtight stainless steel or ceramic container to extend the life of your coffee. We recommend the Airscape® brand, a leading brand on the market. If you have space, don't hesitate to place the original packaging in this container for double protection.

Conservation - nf

And to make your coffee last even longer? You might consider using a freezer, as opposed to a refrigerator.

  • The freezer: This is a hot topic in the specialty coffee community. At Celsius, we're trying to tell you about what we've tested ourselves. We've compared the same coffee roasted months ago, one frozen and the other in the open air, and obtained radically different results. Frozen coffee retains most of its aromas, although it's always better to consume it fresh, while coffee left in the open air for several months deteriorates severely, revealing unpleasant aromas. We believe the freezer is a very good long-term storage solution. Since roasted coffee contains little moisture, storing it in the freezer won't fundamentally change it, but will considerably limit its aging and freeze it at a given moment.
  • The refrigerator: Here, however, the coffee will absorb unwanted moisture, which will dilute its aromas. The spongy nature of coffee will also cause it to take on the tastes and smells of the various foods in your refrigerator. We're not particularly fond of Reblochon-flavored coffee, but no judgment if that's the case for you.

One piece of advice, however, is to buy freshly roasted Celsius coffee frequently, rather than stockpiling large quantities in your cupboards. Even in times of crisis, Celsius will always be able to provide you with fresh coffee!
