how to keep coffee beans fresh

If you want to enjoy a delicious and aromatic cup of coffee, always use fresh and high-quality beans.

Have you ever tried storing packaged beans with a degassing valve? They stay fresh for about fifteen days in the sealed bag. But, the ground coffee beans could start losing flavor in less than an hour.

Coffee beans could last for weeks or months, depending on its exposure to four factors: light, moisture, temperature and air.

While the coffee won’t go stale instantly, the aroma will begin to disappear a few minutes after the beans are ground.

If you want to keep your coffee beans fresh for as long as possible, protect them from conditions that affect their freshness, such as light, moisture, heat and air. Here’s how you can do that.


Don’t Expose Coffee Beans to Day Light

After roasting, keep your coffee away from direct light, otherwise, it could go stale. So, store them in opaque containers or in dark areas to keep their freshness. Displaying your coffee beans might ruin its taste as prolonged exposure to light is bad for them. Choose dark airtight containers to avoid exposure to light. Make sure you store them in room temperature.

Lower the Moisture

Keep the moisture content lower than 13%. The moisture levels of the product can affect its flavor and shelf life. If the moisture is lower than 9% the coffee beans may lose its flavor. But, if it is higher than 13 percent, they will mold and spoil easily.

During storage, make sure that the coffee beans will not be exposed to too much humidity. So, the key is to lock away moisture. Or else, your roasted beans can go bad instantly. Humidity may not be good to the overall state of your roasted coffee bean. Always store them in dry areas. While some people also refrigerate their coffee beans, freezing them may cause condensation and make your beans go bad.

Less Air for the Coffee Beans

Don’t expose your coffee beans to air. Oxygen is a coffee killer, so be sure to pick an air-tight container to keep your coffee beans from oxidizing. If not, they can go bad in a few days and taste old.

Less Heat

Keep your coffee beans from heat, until you are ready to grind and brew them. Coffee beans lose their flavor when exposed to heat before they are ground and brewed. Keep the storage cool for freshness.

In a nutshell, the best way to store your coffee beans is to put it in an air-tight and opaque container and keep them in a cool, dark place.  As a rule, it is not a good idea to keep the beans in the fridge for daily use, because the cool temperature would add in extra moisture to the jar. If you are going to use it every now and then, each time you open the container, you will let in the moisture and cool air. The best option is to grind the beans right before using it.  Then, keep it in smaller airtight jars, put it in a cupboard, and refill it with ground beans as needed.
