How to store coffee beans: packaging, temperature, humidity

It is important to know how to store coffee, cereal and ground, because if you do not comply with the necessary conditions, the drink will lose its flavor. Fans of certain varieties often buy the product for future use. Storage of grains at the right temperature and in a suitable container allows you not to lose the pleasant aroma and richness of the taste of the cooked beverage.

Buying grains 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 savings( large packaging costs several times cheaper).And how can you be sure that the store respected all the necessary conditions? To the morning cup of coffee gave you only pleasure, and the fragrance of vivacity spread throughout the house, find out all about the rules of storage of the product.

Four factors are listed in descending order, which have a detrimental effect on the bouquet of flavor and taste of fresh coffee beans:

1. air;
2. humidity of air;
3. indoor temperature;
4. light.

General storage rules

Green coffee beans are the most resistant to loss of taste qualities. Store green coffee beans only in a sealed jar, so that the air harmful to this product does not penetrate into the package. The bank should be placed in a dark place, where the sun's rays do not penetrate. Raw grains can be stored for more than 1 year if you comply with all the necessary rules.

Fried coffee, to which everyone is accustomed, stores much less green. The factory packing with the valve preserves the aroma about 2-3 months( the date is indicated on the package).After opening or mechanical damage, the shelf life is reduced to 15 days. Especially demanding "caffeines" advise to use the packaging for 10 days. This does not mean that the drink will become unsuitable for consumption, but a decrease in flavor and flavor is ensured.

• Packing .When dissecting, cut only a small corner. After the necessary quantity of grains has been spilled release the maximum amount of air, several times wrap the cut off part of the package and fasten it with a clothespin.
• Bank .The main condition is tightness. Storage of coffee in a glass or plastic jar with a sealed lid has a longer time.

Special package

When offering to store coffee beans in a package, experts say not about thin plastic bags with handles. In stores specializing in the sale of tea and coffee drinks, you can buy special packages for storing coffee beans. They are made of thick polyethylene with a layer of foil. At the top is a ziplock( hermetic buckle), from the bottom there is a special valve.

The advantages of using packages are obvious.

• In a buttoned bag with a grain or ground product do not penetrate foreign smells. Grains have a porous structure, which contributes to the absorption of foreign flavors. Ziplok protects not only from air, but also from excessive moisture.
• Fresh coffee emits gases. For this, the package is equipped with a special valve, which releases air from the package and prevents it from penetrating inside.
• The package can be compressed, which will result in product sealing and minimizes air penetration between the grains.
• Due to the interlayer of aluminum foil packaging prevents direct sunlight.

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

Bank

Preferred can material - glass, clay, ceramics. The bank should have a tight-fitting lid( with a layer of silicone), which will prevent the penetration of moisture and air. Prefer banks with opaque walls to protect the product from light.

Storage of coffee in sealed containers has a number of drawbacks compared to special bags.

• Immediately after roasting in the gasses, gases are formed, so it is better to wait a couple of days before placing the fried product in the jar.
• After closing the lid, air and blocked moisture remain in the jar, which contributes to the oxidation process.
• Transparent glass transmits light, it is better to wrap this jar with dense material.

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

Where to store?

The storage of coffee has a different period of time, depending not only on the packaging, but also on the location. Store the product in a closet, refrigerator and freezer. Each of the places has both advantages and disadvantages.

• Kitchen cupboard.

This place is ideal for storing coffee, which you grind and brew daily. Optimum temperature, absence of moisture and darkness are necessary conditions for the safety of the product. Do not put a packet or a can of grains in the closet, located near the oven or stove, and also opposite the window that is not facing the sunny side.

• Refrigerator.

Despite the widespread belief that coffee can and even needs to be stored in a refrigerator, do not conduct such an experiment at home. The temperature in the refrigerator compartment ranges from + 2 ° C to + 6 ° C.It is not sufficiently low and will not provide freshness to the product. In addition, with repeated seizures of the package from the refrigerator, the grains are covered with condensate, which turns into water and leads to a rapid deterioration of even the fresh product.

• Freezer.

This is the best place for long-term preservation of fresh coffee. However, you need to immediately sprinkle the necessary number of grains, which you will use for daily grinding. If you freeze the grains immediately after roasting, they will remain fresh 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 the purchase.
