How long can ground coffee powder be kept

When people buy coffee, they usually buy coffee beans, so if you want to make coffee, you need to grind the coffee beans. Because the process of grinding coffee beans is a very tedious process, most people will grind a lot of coffee beans and put them aside, which is more convenient when drinking coffee. However, if the ground coffee powder is left for a long time, it will affect the taste of the coffee, so how long can the ground coffee powder be kept?

Fresh coffee is a wonderful thing. While you can buy freshly brewed coffee at a coffee shop, if you roast and grind your own beans, you can ensure that you wake up to a fresh cup of coffee at home every morning. As for how long coffee beans can be stored, much depends on the storage method used.

Unroasted coffee beans

Coffee beans can last for several years if kept dry and unroasted. During roasting, the oils in the coffee beans migrate to the surface and quickly become rancid. Therefore, after the coffee beans are roasted, the storage method becomes particularly important.

Roasted coffee beans

Whole coffee beans that have been roasted and have released their oils can be placed in an airtight container and stored in a cool, dry environment at room temperature. Whole coffee beans can be stored in these conditions for one month.

Vacuum packed coffee

Most coffee you buy comes in vacuum-packed plastic bags. The vacuum process removes oxygen and carbon dioxide from the container, which helps keep the coffee grounds fresh. Once the container is opened, the coffee will only remain in good condition for 7-10 days.

Grinding coffee beans

If you buy whole coffee beans and grind them yourself, the ground coffee will last for 2 weeks.

How to keep ground coffee powder fresh:

1. After opening the package of bagged coffee powder, be sure to fold the opening and clamp it with a clip to prevent the coffee powder from coming into contact with air. When the coffee powder comes into contact with air, it will produce an oxidation reaction, affecting the original flavor of the coffee powder and greatly reducing the quality of the extracted coffee.

2. After sealing the bag, put the bag into a sealed can for storage. It is best to use a container with good sealing performance such as Lock&Lock;

3. Never put coffee powder in the refrigerator; coffee beans should be stored in a dry and cool place.

Refrigerated coffee beans

Many people mistakenly believe that storing coffee in the refrigerator is the best way to store it. But that's not the case. Coffee does not tolerate humidity, air, and extreme temperatures well. When you take your coffee out of the refrigerator, extreme temperature changes can affect freshness. In addition, condensed humidity can also cause coffee beans (powder) to spoil prematurely.
