Coffee bean sealed jar, easy to manage freshness
Coffee lovers around the world know that the freshness of coffee beans is crucial for a great coffee - drinking experience. Now, there's an innovative product that can help: a vacuum coffee bean storage jar with a built - in time compass.
1. Superior Fresh - keeping Function
This storage jar comes with a newly upgraded vacuum - pumping button. With just 5 - 8 quick presses on the palm of your hand, most of the air inside the jar can be removed. Once the large button can't be pressed and is at the bottom, it indicates that the air inside the jar is basically evacuated. To open the jar, simply press the small button to release the air, and then the large button will pop up.
Air contains 78% nitrogen (\(N_2\)) and 21% oxygen (\(O_2\)). This product can remove more than 90% of the air, creating a low - oxygen and low - pressure environment. This effectively inhibits the growth of bacteria, prevents moisture and mold, reduces oxidation, and extends the freshness - keeping period of coffee beans.
2. Why Vacuum Storage for Coffee Beans?
After coffee beans are roasted, they generally have a 7 - day awakening period. After this period, the flavor is more suitable for drinking. The normal optimal drinking period is usually 30 days. After 30 days, the flavor of coffee gradually fades. Since coffee beans oxidize and deteriorate more quickly when exposed to oxygen, vacuum storage can minimize oxidation and retain the original flavor of coffee beans.

- When pumping vacuum, press quickly and continuously for the best effect.
- The jar cannot achieve a complete vacuum state and cannot replace professional equipment.
- If storing for a long time, check and re - pump vacuum every few days to avoid air leakage.
- Coffee beans naturally release carbon dioxide, which may cause the large button to pop up. This is normal, especially for beans in the bean - curing period and deeply roasted beans.
- When storing liquids or powders, do not invert the jar to prevent blockage.
- Clean the lid with a wet wipe. Do not wash the lid with water. If water enters the lid, let it dry naturally, and do not bake it to avoid deformation or combustion.
