How to keep the roasted coffee and how many days it can be stored in a sealed condition?
Fresh beans are suitable for sealing and preservation in a bag with an one-way exhaust valve. be sure to empty the air in the bag as much as possible after use, and then keep it sealed. Usually put beans in a cool and ventilated cabinet, as long as it is not close to the heat source is not a big problem. If it's not for special reasons, don't put beans in the fridge! Keep it in a cool place at room temperature. Because the low temperature of the refrigerator will bring condensed water to the package. This is the sweet coffee! If you really don't have time to drink, but the beans are very good, those you don't want to throw away can be frozen in the freezer and thaw later. Although the flavor will certainly be greatly damaged, it is better than throwing it away.
1. The air in the refrigerator is cold and dry, so it is easy to evaporate the water inside the coffee beans and lose the fragrance.
two。 There are too many odors in the refrigerator.
3. Due to the low temperature in the refrigerator, the coffee beans encounter relatively hot air when they are taken out of the refrigerator, which will condense into water vapor to cover the surface of the coffee beans. After grinding, these small water droplets will turn the coffee powder into lumps, resulting in uneven cooking and brewing.
4. As mentioned earlier, after the coffee beans have been roasted, the internal reaction continues. If the coffee beans are put in the refrigerator at this time, the coffee beans will be cold and stop the internal reaction, resulting in a loss of flavor.
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.
