Coffee is a crop that, like other foods, can rot.

I believe many people may have a question: "how long will it take for coffee to be out of date?"

There are two ways to explain this question:

One is, when will my coffee exceed the peak of the best drink? (that is, the best flavor period)

One is the coffee stored in the kitchen cupboard. Can you still drink it now? (that is, the retention period)

Here is a brief introduction to what happens after coffee roasting and practical information to help you solve your problems.

Fresh coffee lasts for two to three weeks.

Freshly roasted coffee will maintain its best flavor for about two to three weeks, and once roasted, the beans will take several days to exhaust (carbon dioxide), and then can be boiled to drink.

About a week after baking, the coffee flavor is at its peak, and the coffee has the strongest aroma and flavor characteristics, and it can also show the best alcohol thickness and acidity of this coffee. But once you leave it for a few more weeks, most of the coffee will no longer be fresh.

How to tell if the beans are fresh?

1. Aroma

When the coffee you get has no aroma at all, or has an unpleasant smell and fuel-consuming smell, it is very likely that your coffee is not fresh. Of course, if the coffee is roasted with spices, it can not be distinguished by the aroma, and the taste is needed to help distinguish the freshness.

two。 Taste

The first way to tell the freshness from the taste is whether it tastes mixed or oily. And is the coffee too bitter to make people uncomfortable? In addition to the influence of commercial beans, stale beans will also make drinkers feel the same way.

The "safe drinking period" of coffee is several months.

Although these coffee beans, which have been kept for months, are no longer rich in flavor levels such as flowers, fruit and caramel when they are fresh, they are still safe to drink.

In fact, coffee sold in many places does not indicate the date of baking / manufacture, but only the shelf life. Such coffee is often sold as coffee beans that have been roasted for several months, but these beans may be placed on air-conditioned and dry shelves, so they do not have the problem of deterioration, but they are safe to drink.

Although these coffees are not as delicious as they are when they are fresh, drinking them will not do any harm to your health, as long as the environment is not hot and humid, which will cause qualitative changes in the coffee.

Coffee beans that are usually kept for more than six months and not preserved in a stable environment are not recommended to drink as they may produce toxins that are harmful to the human body.

Of course, there is no need to choose to drink such old beans, here are some creative ways to help you consume coffee beans that have been in place for months:

1. Use these coffee beans to make coffee ice cream

two。 Brew the coffee and use it for baking at West Point.

3. Put it directly in the shoe cabinet, wardrobe and car as odorant.

4. Use it to make coffee beans and chocolate (wrapped in chocolate)

5. Use these beans to practice different hand flushing tools / skills

Do not refrigerate or freeze coffee

In order to increase the lifespan of coffee, some people will put it in cold storage or freezing to prevent corruption, which sounds reasonable, but it is actually counterproductive.

Storing coffee in cold or frozen storage will not prolong its shelf life because it will continue to release aroma. Whether they are at room temperature or in the refrigerator, they release these gases.

Keeping the coffee at a cold temperature will not lengthen the six-month shelf life, because there is no need to keep it below zero at all. In fact, storing coffee in cold or frozen storage may shorten its shelf life. When you put coffee in the refrigerator or freezer, a sudden change in temperature usually causes moisture to form inside the bag, just like taking out a drink in the refrigerator. Although stored in a cold environment, the packaging will become wet and the beans will go bad.

To preserve coffee beans, as long as you master the following principles:

1. After opening the coffee beans, be sure to use sealed cans or clips to seal. Choose small packages when you buy, don't hoard beans, buy as much as you drink, and speed up turnover as much as possible.

two。 No matter whether the beans are opened or not, please put them in a cool, dry place with no sunshine, light, temperature and humidity.

3. Coffee beans are just like other foods, no matter how well the preservation conditions are controlled, it is best to drink coffee beans as soon as possible, love should be timely!

Use up the old coffee beans!

No matter how hard we try to consume the fresh coffee at hand, there will always be some coffee that hasn't been drunk for months, and as long as it's properly preserved, it's safe to drink. Anyway, these beans are hard to come by. It can also be used in cooking, baking and practicing hand brewing.
