How many days can the shelf life of ripe coffee beans be stored?

Others: remaining thin-skinned beans, bad beans, dried beans that do not completely produce sour taste, shell beans with only shell, and so on.

The judgment of time:

To see if the packing date is recent, the shelf life of coffee beans is generally one year, and the shelf life of coffee beans is less than one month, so it is best to use coffee beans baked within a month. Freshly roasted coffee beans have the most charming aroma and rich taste.

Judgment during grinding:

After fully roasting and extracting water, the coffee can be brewed into delicious coffee, which can be judged by grinding. When grinding, good coffee beans will gently make the sound of salad salad, gently shake the hand, the original taste of coffee is overflowing. Shoddy coffee beans have a creaking sound. There is a feeling of sticking during grinding.

Judgment at the time of extraction:

The easiest way to make delicious coffee is to sigh the filter paper. When brewing and extracting, there is also a way to judge whether the coffee is delicious, that is, when it is in hot water, the powder is not inflated, and when the coffee is fully roasted and extracted water, there will be a beautiful and meticulous foam puffing up.

For example, we use Kraft paper aluminum foil bags with one-way exhaust valves and seals that can be used repeatedly, but this kind of packaging is not suitable for long-term preservation of cooked beans. So the jar of one-way exhaust valve is also not recommended. The acid is sharp and bright → 2. The bright aroma of acidity enhances → 3. The acidity softens the aroma and sweetness of → 4. All kinds of flavors tend to balance → 5. The sour taste and the diminished aroma began to appear in → 6. The stale defective flavor is obvious (beyond the best flavor period).

The speed of this process varies according to the preservation and baking depth of cooked beans, and other people's taste experience and taste ability are different, so some people can feel this phased change in 3 days, while others think it will take 5 days to change. The arrow mark is for reference. Because the flavor is constantly changing, we should actually use high-pressure extraction according to the taste we drink and the length of the best flavor period, so the flavor is magnified and compact, so it is not suitable to be made when the flavor is too bright or too exciting. this is why Italian style mostly uses moderate baking degree and blended beans, the purpose of which is to make the flavor balanced and reduce the irritation.

Therefore, the flavor trends of 3 and 4 in the flavor trend mark are more suitable for Italian style. In addition, Italian extraction of soybean oil that is too fresh will be very rough, affect the taste and appearance and dissipate quickly.
