The best way to constantly enjoy freshly made coffee & ndash; this is to store the coffee beans and grind them into the right number of portions just before making the drink.
How can you properly store roasted & nbsp; coffee beans ? The most optimal solution is to hide coffee in an opaque jar of ceramic, glass or food tin with a tight-fitting lid and put it in a place protected from light, while the room must have normal humidity and average temperature.
Coffee fragrance, the most important indicator of good coffee, depends on the essential oils found in the beans.
When frying grains, oils are intensively released, forming a breathtaking aroma.
These compounds are volatile and evaporate over time, making coffee taste poor and aroma inexpressive.
The chemical composition of coffee beans is very complex, so their quality is directly affected:
- Oxygen;
- Sunlight;
- Humidity level;
- Odors.
Oxygen
The more oxygen, the faster the essential oils responsible for smell and taste disappear from coffee beans, simply & ndash; coffee fizzles out.
A can with a tightly closed lid is essential for storing coffee beans. It is even better if the containers are small to leave less space between the grains and the lid.
Sunlight
Ultraviolet radiation has a detrimental effect on the composition of coffee beans, triggering irreversible chemical processes.
Coffee in grains, sold in stores from large glass jars, by definition does not have a multifaceted taste and aroma, having lost at least half of its bouquet.
Humidity
Increased humidity is detrimental to coffee beans, making them faded and tasteless.
Optimal air humidity & ndash; up to 55% - 60%. Moreover, for & laquo; capricious & raquo; coffee grains it is important that the humidity does not change too sharply & ndash; this may result in the taste of wood or paper.
Foreign odors
High hygroscopicity makes coffee beans vulnerable, so it is advisable to store coffee separately from spices, seasonings and flavored products.
If you are not comfortable keeping your coffee in a jar, you can replace it with a thick foil bag, which is closed with a special clip clothespin.
Coffee bean has a porous structure and absorbs extraneous aromas well, so any alien smell will certainly appear in the finished drink literally immediately after the aromatic & laquo; neighborhood & raquo;.
Expert opinion
After roasting, coffee beans release carbon dioxide for another 2-3 days, so the grains are not packed immediately.
It is worth considering that freshly fried grains smell very weak, increasing their aroma every day.
The peak occurs from day 7-8 and lasts up to a month, after which the essential oils gradually evaporate.
There are packages with a degassing valve through which carbon dioxide is released: they prevent oxidation and help preserve the entire taste palette of freshly fried grains. Suitable for storage.
Buy coffee for a short time & ndash; 2-3 weeks, periodically changing brands, then your house will always have a delicious aroma of fresh and tasty drink, tirelessly pleasing with new appetizing shades!
