There are thousands of coffee beans storage products on the market, which are made of glass, wood, stainless steel, iron and even plastic. We only supply one kind, which is made of the stainless steel with a vent on the lid, as the picture showed. It’s the most well-known storage product on the market. Why is it so popular? Before answering this question, I’d like to talk something about how to storage the roasted coffee beans.
We all know there are several key factors for storing coffee beans, it needs a sealed, cold, dark and dry environment.
Sealing is the main condition for storing coffee beans, to reduce the exposure of coffee beans to oxygen, which will greatly damage the flavor of coffee once oxidation reaction occurs.
Cold storage is also one of an important factor for coffee beans. The aroma of coffee beans will evaporate under high temperature, and will also produces a lot of carbon dioxide in this environment, and shorten coffee beans fresh life.
What’s more, do not store the coffee beans in the freezer, its must be in a dry environment, but do not put it in too dry place, the humidity is preferably above 54%.
So, this kind of canister was designed. It’s thin and tall, just a small oxidizable area of coffee beans. Part of the carbon dioxide released by the coffee beans will remain at the bottom, forming an anti-oxidation layer, which can protect the coffee beans. Besides, there is a vent on the black lid, can help to discharge excess carbon dioxide from the canister, and we can also put a date wheel on the lid, you can select the purchase or expiry date for optimal coffee freshness. Every popular product has its own unique design concept, including the size, material, and other details.
Please correct me if there are any deficiencies.
