Hanging-ear coffee, as a way to simplify the brewing process and provide us with a cup of delicious coffee more easily, has been widely accepted by coffee lovers since it was invented in 2001. When it is not convenient to use the brewing utensils, we just take out a bag of hanging ears, gently tear open the seal and pour in hot water, and a cup of hot coffee will come out.

Hanging ear seems to be as easy to drink as instant coffee, but we must not forget that the coffee powder is ground from freshly roasted coffee beans!

When roasted coffee beans are ground into powder, about 70% of the carbon dioxide is lost. Although there is still 30%, this part is lost several times faster than in coffee beans. The role of carbon dioxide is to protect coffee from deterioration caused by moisture, oxygen and other factors in the environment, that is, deterioration. But once ground into powder, this protective effect will soon disappear. At the same time, when carbon dioxide is lost, the aroma of coffee is also taken away.

Speaking of which, I believe that wit must be understood by everyone! That is-if you want to get the same flavor as hand flushing, you have to drink it quickly!

But then again, I've bought all the hanging-ear coffee. how long can I keep a large box here? Coffee beans have the so-called best taste period, what about hanging-ear coffee?

Next, let's take a look at a small experiment to see what the flavor of hanging-ear coffee made from a sunburned Ethiopian bean will look like after 1 month or 4 months with or without antistaling agent.

Beans used: medium-to-light baked sun-baked Essel beans

Bouquet: floral aromas, berries and peaches, with citrus acid and caramel sweetness and a lingering finish.

The steps of the experiment:

1. Prepare 6 inner ear bags and ground coffee powder, and make them into hanging ear coffee.

2. Divided into three groups according to time, each with two ears as a group, one with antistaling agent and the other without antistaling agent.

3. Seal the ear and store it at room temperature away from moisture and direct sunlight.

4. Unseal and cook in the first, second and fourth months, respectively.

Experimental results:

The first group: unseal after 1 month.

No antistaling agent:

The fragrance of the flowers has become very weak, but the main flavor is still well preserved, which can be regarded as during the appreciation period.

There are antistaling agents:

It's about the same as when it was done, and it's still in the best taste period.

The second group: unsealed after 2 months.

No antistaling agent:

There is no flower fragrance, and there is not much left in the main flavor. It will taste sharp and sour, which can no longer be counted in the appreciation period.

There are antistaling agents:

It's about the same as when it was done, and it's still in the best taste period.

The third group: unseal after 4 months.

No antistaling agent:

Rush out the taste becomes sour and astringent, the aroma completely disappeared, is no longer in the appreciation period.

There are antistaling agents:

The fragrance of the flowers becomes weaker, but the main flavor is still well preserved, which can be regarded as in the appreciation period.

These are the results of this group of experiments! From the experimental results, it can be found that in the absence of antistaling agent, the best taste period of hanging-ear coffee is no longer than that of coffee beans (the best taste period is about 7-20 days). After more than a month, the flavor was basically lost.

By the way, two extra packs of hanging-ear coffee with the same conditions have been prepared for 9 months, and the taste is so sour. Please don't try.

Conclusion: good things should be drunk as soon as possible!

Most of the domestic coffee shops sell homemade hanging ears without preservatives, which means we need to drink it as soon as possible after we buy it home (preferably no more than a month). Remember to pay attention when you hoard goods!
