Published: 2026-08-23 Author: World Gafei

Last Updated: 2026/08/23, In our life, there are all kinds of controls, stripe control, lattice control, coffee control. The word "control" is a good expression of the degree of love for something. Just imagine that you have a cup of coffee every day. I order takeout when I don't have time. But as long as you have time, you want to have a drink in the store? Want to communicate with baristas / coffee owners,

In our lives,

There are all kinds of "controls"

Stripe control, lattice control, coffee control.

The word "control" is well expressed.

The degree to which one loves something.

Just think of you every day.

Do you have a cup of coffee every day?

I order takeout when I don't have time.

But as long as there's time,

You want to have a drink in the store?

Want to communicate with baristas / coffee owners,

Buy beans and so on.

You've walked a lot and seen a lot of scenery.

Drank a lot of coffee.

Swimming deeper and deeper in the coffee pit in the ocean ~

It's a standard coffee controller.

Squeeze the coffee bag and smell it.

It's a mistake!

As a coffee control

Must have bought coffee beans in a coffee shop!

But I don't know if you noticed a detail.

Every time we pick up the bag,

Always subconsciously pinch the bag of coffee beans in your hand and admire:

"Oh, it smells good, you bean!"

Coffee shop owner: "Hmm!"

Huh? What do you think? Can't you squeeze the bag?

To the duck, no!

When the coffee is freshly roasted

After cooling down to room temperature, it can be packaged in the bag.

And when the coffee beans are in a very fresh state

Beans slowly emit carbon dioxide.

This carbon dioxide is one of the factors that keep coffee beans "fresh".

And the air pressure in the bag can also help raise beans.

Squeeze bag = exhaust gas = lose aroma of coffee beans

This move will affect the quality of coffee.

For coffee beans, the air valve is a device that keeps the air out.

It can effectively slow down the aging rate of coffee beans.

So,

Next time, don't use the one-way exhaust valve as an incense hole.

And then squeeze the coffee bag.

Coffee beans bought six months ago

Can I still drink?

Generally speaking,

Food products will look at the shelf life and taste period.

After the coffee beans are unsealed

It is recommended that you finish it within a month.

Well, coffee beans mainly look at the taste period.

The coffee brewed from the coffee beans during the appreciation period will taste better.

Emmm, now that you have bought the coffee, you should drink it quickly!

Don't keep Mr. Coffee waiting for you too long.

Deep-roasted coffee

Is there a little more caffeine?

Contrary to common sense.

Deep-roasted coffee beans

In fact, it is better than moderately roasted, lightly roasted coffee beans.

Contains less caffeine.

Light roasted coffee beans contain the most caffeine.

I can't finish my coffee beans!

Would you like to put it in the refrigerator?

Coffee beans are afraid of moisture, oxygen, light and heat

Store it in the refrigerator and take it in and out.

Condensate will be produced due to excessive temperature difference.

And it is very easy to absorb the odor in the refrigerator!

This will spoil the flavor of the coffee.

So I suggest that all the bosses

The unfinished coffee beans can be placed in the coffee bag.

Pinch the tight seal

Or you can put it in a sealed can.

Put it in a cool and dry place at home

Then finish it as soon as possible within a month.

The most important thing

It is suggested that you try not to hoard too many beans at once.

Avoid causing unnecessary "baby surplus" ~

I don't know if all of you here agree with this sentence:

"Coffee gives us life, while it brings us fun.

It also increases our happiness index. "

Coffee is not just a pick-me-up

It can also enrich the taste of life.

So you who love life

Also enjoy and love what coffee looks like when it is freshest.
