Rule number 1. Limit contact with air
The most important enemy of coffee is air. With prolonged contact with air, it loses its bright aroma, and the coffee oils evaporate, which negatively affects the taste of the drink. In addition, open coffee quickly absorbs moisture and foreign smells, which also spoil the taste. Therefore, first of all, it is necessary to take care of the hermetic container for grains or ground powder. For the first, a glass jar with a tight lid, which should be stored away from direct sunlight, is more suitable. But the ground powder should be stored in the original packaging, choosing coffee in a bag with a special valve and a practical zip-lock, like Melitta Bella Crema LaCrema.
Rule number 2. Separated from other products
Because of its ability to quickly absorb foreign smells, it is preferable to store coffee away from other foods. Ideally, especially for coffee, you need to allocate a whole shelf or a small locker. If this is not possible, the grains can be stored in a refrigerator or freezer in a tightly closed container that does not allow air to pass through. True, this method is suitable if you use an invigorating drink no more than 1 time per day. Otherwise, frequent changes in temperature and the opening of a sealed package can impair the taste of the grains.
Rule number 3. Shelf life
The next recommendation relates to the observance of the shelf life of coffee. Most likely, you will be surprised to learn that a freshly ground product can be stored for no more than 7 days. The exception is prepackaged ground coffee, which uses special technologies and vacuum packages that prolong the life of the product. Of course, the use of overdue coffee is not fatal, but its taste and aroma will definitely be spoiled. In addition, keep in mind that buying coffee beans by weight, you always risk buying illiquid goods. Therefore, pay special attention to the appearance of the beans: if they are shiny and oily, it means they started spoiling and it's worth to refuse to buy them from the idea.
On a note! Avoid disappointment by buying a pre-packaged grain coffee of the famous Melitta brand. On its packaging, you can always find the exact shelf life and be sure that there is a quality product inside.
In addition, you can extend the shelf life of coffee by providing a hermetically sealed container. For comparison: the grain in an open jar can be stored for up to 10 days, in a tightly closed glass container - up to 2-3 months, and in airtight packing with a check valve - up to 2 years.
