Factors that impact coffee freshness
Coffee beans are carefully prepared through a detailed roasting process to bring out complex and delicate flavors. To ensure that your coffee retains this harmonious balance, it’s key to avoid overexposing the beans to elements such as heat, moisture, air, and light.
Here is a comprehensive overview of which factors impact coffee freshness the most, why they interact negatively with coffee beans, and how to prevent them from causing problems.
Temperature
Coffee beans do not bode well with excessively high or low temperatures outside of the coffee machine itself.
Put them too close to your cooking appliances and temperature fluctuations could ruin the beans by speeding up chemical reactions like oxidation. Store them in the freezer, and the beans could lose flavor or attract condensation. For the best results:
● Store beans at room temperature or slightly cooler
● Avoid storing coffee beans near your stove or oven
Moisture
High humidity and moisture can be harmful to coffee beans.
Some people assume that storing coffee beans in the refrigerator with their other food items will help the ingredients last longer. However, coffee beans will actually draw in the moisture from the surrounding foods, ultimately lowering their quality and introducing foreign aromas to the fragrant beans.
To avoid these outcomes:
● Store beans in a completely dry area
● When in doubt, opt for places where you would store grains
Containers
It can be tempting to proudly display your beautiful coffee beans in a transparent container like a glass jar for their aesthetic appeal. However, this type of container can unfortunately be detrimental to the integrity of the beans.
You’ll want to make sure that your beans are stored in a container that keeps them protected from excess UV and oxygen exposure.
Air-tight storage vessels that you can firmly seal work best for this purpose.
● Keeping beans in their original packaging can be fine for short periods, but longer storage should be done a dedicated airtight container
● Opt for a container that is opaque, not transparent
Lighting
It’s important to store your coffee beans away from direct sunlight, because the powerful UV rays can negatively impact the flavor properties of the product. To best preserve your coffee beans, keep the coffee beans in a dark storage area and store them in a cabinet instead of the countertop.
