How to buy and preserve coffee beans

When the baking is finished, the coffee is ready to drink. Of course, it is important to pack as soon as possible to avoid the loss of aroma and keep the coffee fresh. Improper preservation methods will affect the quality and flavor of coffee. For example, after the coffee comes into contact with the air, the water and oxygen in the air accelerate the oxidation process, which will make the quality of the coffee worse.

Packaging is a very important subject in order to minimize the physical and chemical changes of coffee. Due to the small contact air surface, coffee beans last longer in quality and flavor than ground coffee powder. Therefore, to maintain the aroma of coffee, try to start grinding when you want to brew coffee. If there is no sealed container, the ground coffee powder can be stored in the freezer (below zero).

1. Three factors that affect coffee beans: temperature / humidity / sunlight

2. The best tasting period of coffee is 4 weeks for coffee beans and 1 week for coffee powder.

3. The storage period of coffee beans in vacuum packaging: vacuum canisters can be preserved for about 24 months, and flexible film vacuum packaging can be preserved for 12 months.
