How to better preserve coffee beans? coffee beans or coffee powder? how not to lose flavor?
We should know what is the enemy of coffee bean preservation, high temperature, humidity, oxygen and sunlight. Coffee beans are more resistant to preservation than coffee powder, so when grinding coffee, we have to maintain the principle of "now on the sedan chair, now on the ear". Where are coffee beans stored? Sealed coffee bean storage jars are a good option. There are metal and plastic, the latter is cheaper.
Coffee should not be stored in the refrigerator: First of all, we should know that coffee is not stored in the refrigerator, and whether the coffee bag can be properly sealed is very critical. Because humidity has a greater effect on coffee quality than temperature, it is important to seal the coffee bag properly using a sealing can or bag sealing rod. If this problem is solved, the indoor temperature is too high to consider putting it in the refrigerator.
Let's look at the impact of air on coffee quality. The flavor oil of coffee beans is easily oxidized, so before sealing coffee beans, the gas in the sealed can or coffee bag should be squeezed out and sealed. There is no room for air.
About temperature: high temperature will make coffee out of oil, increase the chance and degree of flavor oil oxidation by air. So friends sometimes keep coffee in the fridge, just like tea leaves. Here I just want to say that friends in the north please put coffee beans in winter as far away from the heating place. If you consider putting the refrigerator can also, but to check whether it is closed in the refrigerator, otherwise your coffee into the refrigerator will become a deodorant!
The elements that affect coffee quality are listed in descending order: humidity, air, heat and sunlight. The taste changes after the coffee beans are wet: the coffee becomes more bitter, has no aroma, and has a single taste. High temperature will make coffee out of oil, direct sunlight will make coffee aroma loss.
