A few days ago, I found that there was a canister of coffee beans in the house that I didn't know how long it was stored in a glass jar.In surprise, I made a cup of coffee to drink. The taste is indescribable. Not at all the good taste in memory.
It really looks like a canister of poor coffee beans that have been forgotten for a long time.
I have previously written an article on 11 vacuum coffee canisters that are worth recommending in 2021, click here to view. Today I will only introduce 5 of my favorites.
Why use vacuum cans to preserve coffee?
I often want to drink a cup of coffee brewed with beans roasted from my favorite coffee shop at home. At first, it has a strong aroma, but after a period of time, the taste does not return to before. In the end, I can only reluctantly throw away a large bag of coffee beans. Buy a new pack.
The reason is very simple, that is, the coffee is affected by "air, sunlight, humidity" and so on after being opened for one or two weeks, which makes the coffee go bad.
The oxidative reaction in the adjacent air causes the flavor of the coffee to dissipate and lose its original aroma.
The coffee beans should also be stored in a dark environment without direct sunlight as much as possible, reduce the exposure to light, and avoid factors such as ultraviolet rays to speed up the deterioration of coffee beans.
When coffee beans are placed in a high temperature and high humidity environment, it is easy to absorb moisture and surrounding odors, making the coffee beans stale and deteriorated.
What jars can keep my coffee beans?
General Glass Jar
Generally, glass jars have poor shading properties, and cannot reduce or avoid the contact between coffee beans and air. Switching on and off for a long time will degrade the quality of coffee beans. If you want to use the same coffee beans to brew the flavor as when first bought them, it is necessary to reconfigure the ratio of coffee powder to water in order to enhance its flavor.
Sealed Jar
Most airtight jars have good shading properties. Although they can keep out of contact with the outside air when the airtight jar is closed, they cannot prolong the storage time of coffee beans if they are switched on and off for a long time. It will go bad soon, it is recommended to use it in a coffee shop where the coffee beans are consumed quickly.
Vacuum Canister
The use of vacuum canisters to store coffee beans has greatly improved the ability to isolate air compared to the above two. As long as the air is drawn out after use, the flavor and aroma of coffee can be more effectively maintained, which is suitable for slow consumption of coffee beans. For general household or personal use.
