Preservation of coffee beans with basic knowledge of fine coffee

With the increasing consumption of coffee in China in recent years, China has gradually accepted the western food culture and style. Coffee as one of the three major drinks in the world has its unique charm. With the understanding and deepening of coffee culture, there are more and more forms of existence. Like instant, bottled drinks, raw coffee beans, roasted coffee beans. Of course, for convenience, there is also coffee powder, which grinds roasted coffee beans into powder for consumers' convenience. Of course, it is not a big problem for coffee powder to be used when it is fresh, and it is impossible to sacrifice the freshness and aroma of coffee in order to facilitate it. In fact, there is a big difference in the rate of deterioration between coffee powder and coffee beans, and the difference between them is due to the difference in surface area. After the coffee beans become powdered, their surface area expands hundreds of times, and the range of contact with air is also larger, so the range of oxidation is also larger. The coffee beans are stored at room temperature after baking, and the best drinking period is only about two weeks. If you want to keep it longer, you can refrigerate the coffee beans into small bags and store them in cold storage for months, while the raw beans should be placed in highly sealed cans and placed in thick paper bags in a place away from direct sunlight. If you can avoid high temperature and humidity, it can also be preserved at room temperature in summer.
