The purchase of beans by weight in coffee shops, at first glance, guarantees the freshness and quality of the product. However, this is not entirely beneficial in terms of economy (large packaging costs many times cheaper). And how can you be sure that the store met all the necessary conditions? So, in order for a morning cup of coffee to give you only pleasure, and for the aroma of vivacity to spread throughout the house, find out all about the rules of storage of the product.

In the descending order, here are 4 factors that have a detrimental effect on the aroma and taste of fresh coffee beans:

  • air;
  • air humidity;
  • room temperature;
  • light.

General storage rules

The greatest resistance to loss of taste is possessed by green coffee beans. Green coffee beans should only be stored in an airtight jar so that destructive air for this product does not penetrate the packaging. It is advisable to place the jar in a dark place. Raw grains can be stored for more than 1 year if you comply with all the necessary rules.

Roasted coffee, to which everyone is accustomed, can be stored for far less time than green coffee. Factory packaging with a valve saves the aroma for about 2-3 months (the term is indicated on the package). After opening or mechanical damage, shelf life is reduced to 15 days. Particularly demanding coffee lovers are advised to use the packaging in 10 days. This does not mean that the drink will become unsuitable for consumption, but you will definitely feel a decrease in taste and aroma saturation.

Packaging. When opening, cut only a small corner. After pouring the required number of grains, release the maximum amount of air, wrap the cut part of the package several times and fasten with a clothespin or a special clip.

Jar. The main thing is the tightness. Storing coffee in a glass or plastic jar with a sealed lid makes for longer shelf life.

Special packaging

You can purchase special bags for storing coffee beans in stores specializing in tea and coffee drinks. They are made of thick polyethylene with a layer of foil. At the top there is a ziplock (tight fastener), at the bottom, there is a special valve.

The benefits of using packages are obvious

  • Extraneous odors do not penetrate the zipped bag. The grains have a porous structure, which easily absorbs extraneous odors. Ziplock protects the coffee beans not only from the air, but also from excessive moisture. 
  • Fresh coffee gives off-gas. For this, the package is equipped with a special valve that releases air from the package and prevents it from penetrating inside.
  • The bag can be compressed, which will lead to the sealing of the product and minimizing the penetration of air between the grains.
  • Due to the layer of aluminum foil, the packaging prevents direct sunlight.

The coffee bag can be stored for up to 2 weeks without loss of taste and aroma.


The preferred material for jars or cans is glass, clay or ceramics. The jar should have a tight-fitting lid (with a layer of silicone), which will prevent the penetration of moisture and air. Prefer cans with opaque walls to protect the product from light.

Although, storing coffee in sealed containers has a number of disadvantages compared to special bags

  • Gases are formed in the grains immediately after roasting, so it’s better to wait a couple of days before placing the roasted product in a jar.
  • After closing the lid, air and trapped moisture remain in the jar, which contributes to the course of oxidation processes. 
  • Transparent glass transmits light; it is better to wrap such a jar with something.

Experts strongly advise against using plastic containers for three reasons. Firstly, the material has a specific smell, which is quickly absorbed by the grains. Secondly, containers do not have sufficient tightness (air and moisture will get inside). Thirdly, they have transparent walls that do not protect the product from light rays.

Where it can and can not be stored?

  • Kitchen cabinet. This place is ideal for storing coffee that you grind and brew daily. Optimum temperature, lack of moisture and darkness are necessary conditions for the preservation of the product. Do not place a bag or a jar of grains in a cupboard located near the oven or stove, and also in front of a window facing the sunny side.
  • Refrigerator. Despite the widespread belief that coffee can and even should be stored in the refrigerator, do not conduct such an experiment at home. The temperature in the refrigerator compartment ranges from 35 ° F to 43 ° F. It is not low enough and will not provide freshness to the product. In addition, when the packaging is repeatedly removed from the refrigerator, the grains are covered with condensate, which turns into water and leads to rapid spoilage of fresh coffee beans.
  • Freezer. This is the best place for the long-term preservation of fresh coffee. However, you need to immediately pour in the required amount of grains that you will use for daily grinding. If you freeze grains immediately after roasting, they will retain freshness for up to 2 months. If a suitable container and storage location is chosen, the aroma of freshly ground coffee will fill your home even a few months after purchase.
