A valve on a packet of coffee: a useful invention for keeping freshness

No one doubts that in order to enjoy a cup of coffee, you need to purchase a quality product. For example, buy coffee Lavazza or another respectable brand. But that's not all. It is important to be able to distinguish a real product from a fake. And, of course, follow the advice of coffee lovers: store beans (as well as ground coffee) in suitable conditions.

Fortunately, the Lavazza coffee makers have considered the issue of safety: the special packaging is equipped with a valve. Let's figure out what the valve is for and whether it is worth pouring the contents from branded bags into other containers.

Breathable product

The products of the leading manufacturers of the coffee industry are carefully packaged. It is not just packaged, but sealed in an oxygen-free environment. Technologies using nitrogen and vacuum are provided. Special equipment allows this truly living product to maintain its freshness for the period indicated on the package. A degassing valve is another way to ensure a proper environment after the bag is sealed.

The coffee gives off gas after roasting. The faster and more intensely it is fried, the more carbon dioxide appears. Even after the product is chilled and ready for sale, it continues to breathe. To breathe coffee, there is a special valve on the package: it releases carbon dioxide, but prevents oxygen from penetrating inside.

Storage as the most important attribute of quality

At home, it is difficult to find a container with such parameters. Therefore, Lavazza branded coffee equipped with a valve should not be deprived of authentic packaging. There are customers who have a technique that allows a large volume to be poured into smaller bags (with a zip lock) without air access and stored in the freezer. But for now, this is more the exception than the rule. Standard branded bags with a degassing device will protect coffee from harmful effects in an ordinary cool dry cupboard.

Protecting coffee from harmful influences is a serious task. In the kitchen, he is given a dark place, far from heating devices, without dampness and foreign odors. An increase in temperature by several degrees and access to oxygen lead to irreversible consequences. The loss of aroma will upset no less than the loss of taste. That is why it is sometimes advised to store sealed containers not on a regular shelf, but in a separate freezer. The lower the temperature and humidity, the better for coffee.

How grains are brought to "condition"

Roasting green coffee is an important process that some coffee drinkers want to do on their own. To do this, you need to have certain knowledge and skills: to understand for which variety one or another type of roasting is needed, to carefully regulate the temperature, etc. The belief that grain should be roasted and ground immediately before consumption is not entirely true. It is worth grinding coffee before preparation, but it is better to roast beforehand. Even for cupping (professional tasting), the raw product is fried for a day (and sometimes more). Why? The taste of coffee will begin to appear after the natural release of excess carbon dioxide: this period will be different for different varieties.

Experienced manufacturers distinguish not only three types of roasting: light (up to 205 degrees), medium (up to 215) and dark (up to 230), but up to a dozen of its subspecies. By the way, there is also a stronger roast - above 230 (it is called "maximum", "highest", etc.) The stronger the roast, the greater the degree of gas and essential oils yield, the grain structure changes. This affects the final result - the taste and aroma of the drink. There are so many nuances in this process that it’s even surprising how someone manages to bring the grains to the required state in a frying pan or baking sheet, without special roasters. After all, temperature rise, uneven frying, improper cooling must not be allowed. And untimely moving (both early and late) to the storage tank!

Probably, some hobbyists manage to master the "individual" roast. But modern rhythms do not allow every coffee connoisseur to accurately correlate the desired acidity, bitterness and sweetness with the degree of roast and the time required to “rest” the roasted beans (until the moment when its taste becomes optimal). It is good that there is a ready-made product (for example, Lavazza Oro black) ready for use. It remains only to cook it according to the recipe.

What to look for before ordering

When ordering a product on the website coffeeynya.ua or purchasing it at the Coffeeynya in Kiev, the consumer can be sure of the high quality of the products offered. We work only with reliable, trusted suppliers, we know thoroughly how branded coffee differs from counterfeit coffee. By the way, even the degassing valve for counterfeit packages looks different.

Before buying Lavazza coffee, the client should determine during what period he will use up one package. And whether he needs a grinding (it is carried out free of charge with a prepayment of the order). If the daily consumption is low, it is wiser to take a few small packs. Naturally, the coffee is better preserved.nits its qualities until it is printed. Lavazza Oro black, like other varieties of "Lavazza", is produced in packages of the same design, but of different weights.
