About the preservation of coffee beans: we should know what is the enemy of the preservation of coffee beans, high temperature, humidity, oxygen and sunlight. Coffee beans are more durable than coffee powder, so we should maintain the principle of "getting on the sedan chair and piercing the eyes now" when grinding coffee. So where are the coffee beans suitable for storage? The biggest enemies of coffee beans are oxygen, moisture, light and heat. Coffee beans should be placed in an opaque and airtight ceramic container immediately after opening, and then placed in a dry and cool place. Do not use plastic or metal containers to prevent coffee beans from inhaling the smell of plastic or metal. And they all exist in the form of beans-fresh grinding tastes the best.

Sealed storage tanks for coffee beans are a good choice. About whether the coffee should be kept in the refrigerator: first of all, we should know whether the coffee is kept in the refrigerator and whether the coffee bag can be properly sealed is very important. Because moisture has a greater effect on coffee quality than temperature, it is particularly important to use sealing cans or coffee bag sealing rods to properly seal coffee bags. If the indoor temperature is too high after solving this problem, you can consider putting it in the refrigerator. Let's look at the effect of air on the quality of coffee. The flavor oils of coffee beans are easily oxidized, so the sealed cans or the gas in the coffee bags should be squeezed before sealing the coffee. There is no room for air. About temperature: high temperature will cause coffee to produce oil, increasing the chance and degree of flavor oil being oxidized by air.

So friends sometimes put coffee in the refrigerator, just like keeping tea. Here I just want to say that friends in the north please put the coffee beans away from the heating as far as possible in winter. You can also consider putting it in the refrigerator, but check whether it is closed and put in the refrigerator, otherwise your coffee will become a deodorant in the refrigerator! Among the many elements that affect the quality of coffee, the order from heavy to light is as follows: moisture, air, high temperature, sunlight. The change in the taste of coffee beans after being wet is that the coffee becomes more bitter, has no aroma and has a single taste. High temperature will cause the coffee to produce oil, and direct sunlight will make the coffee lose its aroma.

It is recommended to buy only the amount of coffee beans you can drink within two weeks at a time, and the speed of microbes and oxidation is appropriate at room temperature-freshly roasted coffee beans can be kept for two weeks at one room temperature. If you can finish your coffee beans within two weeks of baking, it is strongly recommended to keep them away from light at room temperature, so that the same bag of beans can feel its variety. Feel its different flavor every day, not only add some color to life, but also increase experience, which is very helpful to judge the freshness of coffee beans.

Then the cooked coffee beans produce carbon dioxide because they oxidize, which will cover most of the flavor of the coffee beans, so we have to put them in an one-way exhaust valve bag with a sealing strip for preservation, but when we open the sealing strip many times, there is not only carbon dioxide but also the aroma of coffee beans, so we must finish this bag of coffee beans within a month. Otherwise, no matter how we try to save it, we won't get the perfect coffee in the end.

If you buy coffee powder directly, you can't drink it all at once, which is very fatal to the flavor of coffee. After grinding into powder, due to the substantial increase in its contact surface with air and rapid oxidation, the freshness of coffee will be lost immediately, and the original mellow flavor of coffee will gradually disappear. Freshly baked coffee beans are ground into powder, and the flavor changes within two or three days. So, if you are not just for a caffeinated drink, but also want to taste the mellow coffee that represents the true coffee spirit, it is recommended that you do not buy coffee powder directly unless you consume it quickly in a day or two. buy coffee beans and a bean grinder or go straight to coffee cow non-coffee to enjoy freshly ground coffee!
