Professional barista communication, please pay attention to coffee workshop (Weixin Official Accounts cafe_style)

The rich and deep aroma of coffee comes from the air, and the sense of smell reaches the highest level of enjoyment. Are you also the same as most families, buying coffee beans to enjoy coffee every day and storing them at home, only to find that the coffee beans are hard to put into oil? (I don't know if I've had this experience too…)

How to preserve coffee beans? Simply remember the following 3 not 3 to make home coffee aroma and fresh longer lasting…

1 . Buy freshly roasted coffee beans How to choose freshly roasted coffee beans? Coffee beans are mainly composed of fiber, and when the fiber in coffee beans stops moving, it is the best extraction time. Fresh coffee beans expand rapidly and produce a lot of gas once they come into contact with hot water. However, vigorous exhaust will hinder the water saturation of coffee.

Therefore, choose freshly roasted coffee beans, not only can make coffee beans stored for a long time, but also can taste the best flavor, so don't forget ~ before buying coffee beans to see not the final shelf life but the roasting time Oh!

2 . Make sure the coffee bag is sealed tight.

I believe that everyone must know that if the leftover cookies are not well isolated from air and moisture, the final outcome must be that the cookies are soft and lead to poor flavor. By analogy, coffee beans are also the same, if not after the opening of the coffee bean bag sealed tightly, it will also affect the quality of coffee beans, so when we open the coffee bean packaging, we must remember to seal the bag mouth, to avoid coffee beans and air contact, the best way is to use a bag with sealing layers can effectively isolate the air.

3 . Use airtight containers and avoid hot and humid places

In order to avoid coffee from being affected by the biggest enemies-air, humidity, heat and light, the most effective way to isolate the air and humidity is to use a sealed can to preserve coffee beans, the sealed can is best to use glass material, good cleaning and no metal taste, so as not to indirectly affect the flavor of coffee beans; In addition, the coffee bag will be placed in the sealed can to achieve the best preservation effect. In addition, coffee beans will be stored in a cool place to avoid heat, light affect coffee beans, so that coffee beans can effectively extend the shelf life

Tip: Small series recommended coffee sealed cans

1 . Do not grind in advance, grind as much as you use

When coffee is roasted, it begins to awaken its drinkable components, such as amino acids and sugars, and begins to reduce its shelf life. After opening the package, the probability of oxidation of coffee beans will increase due to contact with air, resulting in a change or decrease in flavor and aroma. After grinding, coffee beans will increase due to contact with air, resulting in excessive oxidation, resulting in a greatly shortened shelf life. Therefore, the best way to taste delicious coffee is to buy only one to two weeks of coffee beans, and in order to isolate the air, we can immediately after the purchase of coffee beans for nearly a few days of coffee beans, and the rest of the unused coffee beans stored in a closed container, and maintain the "use, grind" mentality Oh! (Xiaobian: In order to drink fresh and mellow coffee, I will grind coffee beans diligently before brewing coffee!)

2 . Do not squeeze the valve bag, it will greatly reduce the storage time

After roasting, the coffee beans will begin to dehydrate and compress inside, and the air valve bag on the coffee bag is a one-way air valve, which can only discharge gas to the outside in one direction, rather than two-way ventilation. If we squeeze the air valve bag in order to smell the coffee aroma, it will lead to an imbalance in the pressure inside the bag, so that the coffee beans continue to release gas, causing the freshness of the coffee beans to drop significantly, and will also shorten the storage time of the coffee beans.

3 . Do not store in the refrigerator.

Although it is necessary to store coffee beans in a cool place, do not store them in a refrigerator with high humidity.

Coffee beans stored in the refrigerator will not only accelerate the speed of moisture in their internal fibers, but also seriously affect the ability of the fibers in the coffee beans to absorb flavor, so the coffee beans stored in the refrigerator will not become a deodorant? In addition, some people completely sealed in the refrigerator coffee bean container, only to avoid coffee beans adsorption of other flavors, however, do not know that this is the lack of a one-way valve to allow coffee beans exhaust to maintain quality, not to mention the general household refrigerator temperature and humidity do not conform to coffee beans preservation, in the coffee back to normal temperature, moisture will affect the flavor of coffee, and even there will be the risk of ochratoxin infection!
