How to Store Coffee Beans So They Stay Fresh Longer

Good-quality coffee can cost quite a bit, and this is perhaps the reason why the deterioration of taste after a couple of days after opening the package might seem rather annoying. However, should your morning coffee be flat and too bitter for your tastes, the problem might actually lie in the manner you store the coffee.

The changes that occur during the process of roasting affect the coffee from the first moments following this process. Light, air, temperature, and moisture are only some factors that speed up the process of staling. Luckily, however, several simple storage tricks will help maintain the quality of taste.

Why coffee beans go stale

Roasted coffee beans contain several aromatic substances and oils that are responsible for the taste of your cup of coffee. With time, oxygen will begin oxidizing the substances contained within the beans. As explained by the Specialty Coffee Association, oxygen is among the leading factors that lead to stale coffee. Scientific literature has established that minimizing oxygen exposure could dramatically increase shelf life.

In addition to oxygen, light could also cause premature degradation. Exposure to direct sunlight or high-intensity light from your kitchen could break down the oils and other flavor compounds in coffee. This explains why coffee stored near windows or close to the stove could become stale very quickly.

The best place to store coffee beans

The best location for most homes would be a cool, dry, and dark kitchen cupboard. It is advisable to store beans in an airtight and opaque container far from any source of heat. Steel and ceramic containers that have tight closures have been found to be effective.

Most coffee roasters also pack coffee beans in bags fitted with one-way valves. This ensures that carbon dioxide escaping from fresh coffee can easily pass through while preventing contact with air. In most instances, keeping coffee in its original sealed bag in a pantry is effective. Another wrong approach is to store coffee in clear glass containers on your kitchen counter. Such jars may be aesthetically pleasing, but they expose coffee beans to light daily.

Why air is coffee’s biggest enemy

With each opening of the container, oxygen flows in. Such continuous contact makes the smell fade gradually and results in the musty, paper-like smell that can be found in older coffee. Research mentioned on the Specialty Coffee Association website shows that oxidation starts affecting the aroma very fast after contact.

It might help if you started buying coffee in smaller portions. Instead of having a huge portion for months ahead, try to purchase only an amount for two to four weeks. Whole coffee beans last longer than ground ones because of the lesser exposed surface area.

Should you refrigerate or freeze coffee?

Despite seeming to be a natural choice, many coffee professionals recommend avoiding storage in your refrigerator. Odor absorption from other foods and temperature fluctuations that can introduce moisture into the beans are undesirable for maintaining flavors.

Freezing may work differently. There are coffee experts who claim that if you have more beans than you need and do not plan to drink them soon, you can freeze them in tightly sealed portions and avoid defrosting and refreezing. For daily consumption, pantry storage is often preferable.

Common coffee storage mistakes to avoid

However, some simple practices tend to reduce their longevity more rapidly than one might think:

• Keeping beans exposed to direct sunlight
• Storing coffee next to the cooker
• Utilizing clear containers for coffee on kitchen counters
• Purchasing excessive amounts of coffee in one go
• Grinding beans in advance before brewing them
• Storing coffee in the refrigerator daily

These small modifications will certainly make a huge difference.

Fresh coffee starts with good storage

The quality of coffee is not just about what kind of beans one purchases. It also depends on what one does once he or she takes them home. Preserving the beans from exposure to oxygen and light helps keep the flavors created during roasting intact. Sometimes the solution is simple: storing them in an airtight bag, keeping them in a dark place, and purchasing in small quantities can make a world of difference.

Sometimes all that is needed for better-quality coffee is a change of storage place.
