How to open a coffee bag?
Coffee bags come with a tight-sealing these days to make sure that the coffee beans remain fresh inside the bag and to prevent them from going bad. This sealing is also helpful in retaining the aroma and taste of the coffee. To open a coffee bag, follow the directions given below:
- First of all, you have to look for the black tape on the upper side of the coffee bag. Once found, unclasp the bag. For this, all you need to do is just pull back this black tape from the backside.
- Then take out the scissor and cut along with the line which is visible under the top opening of the coffee bag. Or you can simply tear down the top opening.
- Now, coffee beans can be seen inside the bag as it is opened.
- You can either take out the whole coffee and store it inside a glass jar or you can keep it in its original packaging.
NOTE: it is better to transfer the coffee from the bag to the glass jar. Doing so will help you keep the coffee for a relatively long time frame and retain the aroma of the coffee beans.
Are coffee bags airtight?
Yes! Most coffee bags these days come in airtight and properly sealed format. It is recommended by the National Coffee Association to keep freshly roasted coffee in an airtight container. This helps to maximize and maintain the flavor and freshness of your quality coffee beans or coffee grounds. Otherwise, excessive exposure to air, light, heat, and moisture will ruin your quality coffee beans or grounds.
How do coffee bags work?
Coffee bags work the same way as tea sacks. The ground coffee is fixed inside a warmth-fixed material pack. You just have to add bubbling water and leave the coffee to the implant for about 3 minutes. After 3 minutes, mix your coffee, crush the pack that you dipped in the bubbling water, and eliminate the coffee bag. Your cup of coffee is READY to be enjoyed and appreciated.
Why there is a valve in the coffee bag?
There is a valve in the coffee bag that is meant to serve two purposes; one is to make you able to smell the coffee beans and the second (major purpose) is to serve as a one-way valve.
This one-way valve is important to allow internally formed carbon dioxide to come out easily and also to prevent external oxygen to enter the coffee bag. This helps to maintain the freshness of your coffee inside the bag for up to 4 months easily.
If you don’t know about this, read on to have an idea about the logical reason behind it:
When you roast fresh coffee, it starts releasing carbon dioxide into the atmosphere slowly and gradually. The coffee roasting process releases carbon dioxide in a higher percentage which is why it needs proper packaging requirements.
If you don’t keep a gas valve on the coffee bag front, then the carbon dioxide released inside the bag will not have the space to escape, and eventually, the coffee bag will burst out due to excessive carbon dioxide pressure.
How long do coffee beans last in the bag once opened?
Once opened, the coffee beans can stay fresh for up to 2 to 4 weeks. This is because when the seal of the coffee bag is opened, the coffee gets exposed to outside oxygen and the process of oxidation of coffee begins. This will start to gradually ruin the aroma and freshness of your coffee beans that are stored inside the coffee bag.
The process of oxidation can be slowed down by either deep-freezing the coffee bags or storing the coffee inside the mason jars or airtight glass jars.
Can refrigeration help you keep the coffee longer?
Keeping the coffee in the refrigerator can help you increase its shelf life to some extent. But it can still lose its taste and aroma due to the oxidation process. The oxidation process starts exactly after the moment you opened the package. So the only option to make this process slower is to keep your coffee in a glass jar so that the interaction of coffee with the air can be minimized.
