How to store coffee beans and do they expire?

Hi Hive Lovers

If you continue reading this post, you will get answers about what happens to coffee beans that have not been consumed for a long time.

Basically, every food or beverage product must have an expiration date because both of them will experience a period of product resistance to changes in taste and aroma or undergoes decay.

All fruits and seeds also have an expiration date because they are oxidized. What is different is how fast the oxidation process is? To give a clearer picture, let's look at an apple that is split and that is not split, both of which are undergoing oxidation. But an apple that is split open will rot faster, right?

Unlike the coffee beans, it does not decay as a result of the final oxidation process. It only undergoes a change in aroma and taste. Changes in the aroma and taste of these coffee beans, do not mean the coffee beans have expired.
The coffee processors, observers and connoisseurs give the name to the change in coffee beans with the term "coffee beans that are no longer fresh". So, there is no expiration term for coffee beans.

To prevent changes in taste and aroma, coffee beans must have a certain level of water content, storage containers must be clean and airtight. If that has been done, then the coffee beans will last for years.

These are several types of coffee beans that are stored in airtight glass jars. Among them are Gayo Arabica, Gayo Robusta, Wine Coffee, etc.

These are Gayo Arabica coffee beans that have undergone a perfect drying process and are ready to be stored for a long time.

These are Gayo Robusta coffee beans that have also undergone a drying process, the beans look almost like plastic because the water content is at a minimum level, and is also ready to be stored for a long time.

Then why is there a roasting date or expired date on the coffee package you buy?

I don't think it's appropriate to say that coffee has an expiration date, because coffee never goes through decay, but only changes and must call it coffee that is not fresh. It can still be drunk at any time, unless you are a true coffee connoisseur who always wants the perfect coffee taste.

Roasting is the process of cooking coffee to remove water, dry and develop the coffee beans and give the coffee its aroma. In the cooking process there will be a chemical process, the longer the coffee beans are cooked, the more chemical reactions that occur that will change the characteristics of the coffee.

Because coffee beans have undergone a change in characteristics (after roasting), it will cause susceptibility to changes in temperature and it will facilitate changes in taste and aroma. To maintain the quality of taste, coffee that has undergone a roasting stage will be recorded on the roasting date.

The ones in the palm of my hand are some Gayo Arabica coffee beans that have just been removed from the roasting machine, they still look shiny and a little sticky because of the coffee oil content.

These are coffee beans that have been roasted for more than 24 hours, they are in limited quantities and are not stored for a long time, not more than 1 month.

This is ground Arabica coffee that has been roasted and ground since 1 year ago, it has not changed the taste at all, I have tried it myself by comparing with the freshly roasted coffee that is in the palm of my hand above.

Therefore, coffee processors will only roast on demand and will store the fresh coffee beans for a long time.
