The chemical compounds of roasted coffee are complex, but it is proven that the air which contains oxygen reacts with the compounds of coffee, and alter. This leads to unflattering results, we often speak of smell and taste of rancia and harsh impression. It is therefore advisable to buy your coffee in packaging well sealed by your seller. |

coffee is a hygroscopic food , that is to say that it retains the humidity of the air by absorption. This humidity will attack the flavors and in particular alter the essential oils of coffee for a degraded cup result. So don't plan to store your coffee in the refrigerator and this even in a box, it is a far too wet environment, which also promotes the migration of fragrant molecules from other foods towards coffee, it will then be undrinkable in a few hours. |
Light emits electromagnetic radiation, especially due to the photons that participate in the photodégidation of organic compounds and odorous coffee molecules. Cafes that have remained in light therefore lose their organoleptic qualities and oxidize even faster, their color can also change.This phenomenon is accelerated by storage in transparent containers that make the photons cross the container.therefore flee the coffees sold in bulk in large transparent containers, the coffee is often undressing, unless your dealer has just put it in presentation. |
| We often hear about specialists who freeze coffee. This is true and is valid for very small amounts of vacuum wrapped coffee. In use, the coffee must be used very quickly because the defrosting causes a rise in temperature and an increase in humidity which will of course deteriorate if it is not consumed immediately. So don't plan to practice this method. |
However, coffee retains its best taste qualities up to around 60 days, but it can be kept far beyond without real perception of degradation. Consume it quickly, ideally in a period of less than 7 days, respecting the recommendations above.
How to better keep coffee under these conditions?
Do not panic, simple solutions exist, but remember that light, air and humidity quickly alter the coffee.
Freshly roasted coffee:
The ideal is to buy your coffee in opaque, hermetic packets (hermetically closed or welded and more equipped with zip closure) equipped with decompression valves or unidirectional valves, the advantage of this valve is to allow the air contained in the pack of escaping when you press the package, replace that evacuated. This is the solution that Mapala chose.
When the package is open and started:Use the zip and press the package to evacuate the air. If the package has no zip closure, then fold it firmly and use an elastic to keep it closed, or use a pliers. Then store the package in an airtight box in a cupboard to avoid light, humidity. You can also use an opaque (non -transparent), plastic or bamboo box to protect your grain coffee from light, air, and always choose a screw box or with joints. |
In conclusion, be sure to protect your coffee from the air from humidity and light well and if you consume ground coffee, then think about buying a manual or electric mill to grind it on demand, because the ground coffee degrades much faster because the air, humidity are more quickly more quickly. |
