Taste period, shelf life, stupid distinction. Don't say you can drink coffee.

Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.

Coffee has entered the aesthetic era of fine coffee from the instant era to the Starbucks product era. The purpose and requirements of drinking coffee have been more and more in pursuit of wonderful flavor and plant authenticity like tasting red wine.

About the shelf life:

The shelf life of prepackaged food refers to the safe edible period of the product, which is provided by the producer and marked on the product for limited time.

During the warranty period, the production enterprise of the product shall be responsible for the quality of the product in line with the relevant standards or express guarantee, the seller can rest assured to sell these products, and consumers can use them safely.

Before establishing the shelf life of a kind of food, it is necessary to analyze the objective quality changes of food, such as microbiological test, physical and chemical test and sensory examination, and the microbiological index is often the most direct factor affecting human health. Coffee beans (powder) are not easy to breed microorganisms because of their low humidity, and their shelf life is relatively long. generally, the shelf life of coffee in aluminum foil bags is 12-18 months, while that of imported coffee is mostly 2 years.

With so much talk in technical terms, I just want to make two points:

1. The shelf life of coffee is the time when manufacturers make their own decisions according to industry norms and guarantee the quality of sellers and consumers.

2, after the shelf life of coffee stored properly, people will not have any problem drinking, flavorless coffee through sugar and milk can also become a good coffee drink.

So, coffee with sugar and milk tastes good, but it's not necessarily fresh!

If the shelf life is a health and safety issue, then the flavor period is related to the nature of food!

About the flavor period:

Flavor period (also known as appreciation period) the best time for coffee to taste after roasting. Freshly roasted coffee has a self-fermentation process within a week, making the flavor more perfect, after this stage begins to oxidize and volatilize, and the good coffee flavor begins to lose gradually. Therefore, the best taste period for coffee is within two weeks after baking, when the coffee will have a very fresh aroma and rich in oil, the coffee with sweetness has an obvious return to sweet taste, and the coffee powder is obviously expanded after being infiltrated by hot water. this is often a simple way to identify whether it is fresh or not.

How to open fresh coffee:

A large number of practices have proved that the flavor period of coffee cooked beans is basically less than 1 month, and the longest sealed preservation is no more than 2 months. After the coffee is ground into powder, the surface area increases, which accelerates oxidation and volatilization, so the flavor period is shorter, so it is difficult to get the flavor when buying hanging-ear coffee in the supermarket.

Coffee without flavor is only left with incorrect aroma and bitter taste, and some are even tart, which can not represent the characteristics of a brand, origin or grade of coffee at all, so no matter what brand of coffee is good, after the flavor period, it can not be called good coffee, "fresh, fresh, fresh" is the premise of good coffee.

If you are making coffee at home, please do:

If you buy freshly roasted coffee, you may try to buy cooked beans and grind them yourself. Don't hoard any good coffee, just drink it for a month. Hang-ear coffee is best to buy only 15 days, drink it and then buy it!
