During the roasting process of coffee beans, carbon dioxide is released. If you brew freshly roasted coffee beans, because the carbon dioxide in the coffee beans does not have enough time to discharge, it will disrupt the coffee extraction and affect the coffee flavor. It is recommended to drink 3-7 days after baking. When buying coffee beans, you must also pay attention to the roasting date and buy freshly roasted coffee beans as much as possible. Because over time, the coffee bean will slowly lose its aroma and flavor. The best tasting period for coffee beans is to drink them within one month after roasting. You can also enjoy them after a month, but the coffee flavor will be discounted.
Recommended use:
1. Aluminum foil paper packaging bag with one-way air valve. The inner layer of aluminum foil is like a parasol, which can block light and isolate high temperature.
2. Storage Canister with one-way valve. If you are used to using Storage Canister
To save the beans, after multiple uses, there will be air left in the top space of the jar, which will accelerate the oxidation and rancidity of the coffee beans for a long time. Therefore, it is still recommended that you use the Storage Canister with a one-way valve Store coffee beans.
In coffee research projects, many people have begun to use cryopreserved coffee beans. Studies have found that freezing coffee beans can indeed prolong the fresh-keeping period of coffee beans. but! Pay attention but! It's not called freezing and storing the purchased coffee beans in the freezer layer of the refrigerator. Frozen storage requires the coffee beans to be individually packaged according to the single-use amount, put into a food-grade bag or container and sealed. It would be better if it can be evacuated before freezing. The more complicated method is vacuuming and then filling with nitrogen... In short, cryopreservation is still a method with a low input-output ratio for ordinary consumers and coffee shops.
Coffee beans in a humid environment are more prone to spoilage, resulting in a musty smell, which also accelerates the loss of coffee flavor. It is recommended to store the coffee beans in an airtight seal immediately after using them. It is not recommended to put it in the refrigerator compartment, which is not only humid and easy to absorb odors.
Finally, it is recommended that you do not buy roasted coffee beans in large quantities at one time. Just buy enough coffee beans for household use that can be consumed within 1 month, so as to ensure that the coffee beans can be tasted in the best tasting period. During storage, be sure to avoid light, moderate temperature, dry and seal in time to maximize the retention time of coffee flavor.
