Many people buy coffee beans and do not often cook them at home, or buy too many coffee beans at a time, keep them for too long, and finally put the coffee beans in the refrigerator.

For vegetables and fresh ingredients, low temperature can indeed maintain the freshness of the ingredients and can be stored longer, prolonging the shelf life.

However, storing coffee beans in the refrigerator is not a good idea, because when raw coffee beans are roasted, they lose moisture, and caramelization converts the sugar into coffee beans. Roasted coffee beans have a low moisture content and will be extracted when they come into contact with water.

The reason why you can't put it in the refrigerator.

When the coffee beans are put in the refrigerator, there is moisture inside the refrigerator, and the coffee beans will absorb the moisture from the refrigerator and deteriorate (not to mention the smell of other foods in the refrigerator, which will also be contaminated with coffee beans). If the coffee powder is put in the refrigerator, the impact is even more serious, many people will take coffee powder to deodorize, indicating that it can absorb taste very well, and fresh coffee is just as easy to absorb taste. As a result, the brewed coffee may have the mixed smell of other foods in the refrigerator.

Good coffee is basically good beans, which means that when you use beans stored in the refrigerator, you are using coffee that is stale or even partly like coffee grounds. Coffee brewed from coffee grounds can't be delicious, so never store coffee beans in the refrigerator.

What if it's in the freezer?

This part is somewhat controversial, but our suggestions are as follows:

Just stay away from the three reasons that affect the quality of coffee: air (oxygen), moisture and light (temperature). You don't need to store it in the refrigerator. Our coffee bean bag itself has a good breathable valve, which can effectively maintain the quality of coffee beans.

What if it's already in the fridge?

Earlier, the guest asked, can the coffee beans from the refrigerator be baked in the oven?

Don't do this, just let the coffee beans warm at room temperature and don't bake them again. Heating not only does not add aroma, but also makes the quality worse.
