Factors Determining How Long Coffee Beans Last

Three main factors affect the overall shelf life of coffee beans. Taking note of these when you purchase your coffee beans will help you to keep your beans for longer without losing flavor.

• Type of coffee bean. Robusta and Arabica coffee beans are two of the most commonly used and popular beans. Arabica beans tend to have a longer shelf life than Robusta beans due to their lower oil content.
• Roasting level. Lightly roasted beans have a shorter shelf life than darker roasted beans because they contain more moisture and are more susceptible to oxidation.
• Packaging. Airtight packaging is essential for preserving the freshness of coffee beans. Oxygen, light, and moisture can all cause coffee to deteriorate quickly.

The Type Of Bean Affects Gow Long Coffee Beans Last

Green coffee beans last the longest and can be stored for a year if stored using the correct methods. However, not many people have the ability of the means to roast their own coffee beans, so which coffee beans will last the longest?

Roasting coffee beans release oils held within the beans, which is what produces the flavor in coffee. These oils can go rancid over time, causing the coffee to spoil.

Coffee beans with a lower oil content, such as Robusta beans, will have a longer shelf life than beans such as Arabica, which have a high oil content. The only problem with lower oil content in the beans is the coffee’s less robust flavor profile.

The Role Of Roasting In Coffee Bean Shelf Life

Roasting is a crucial step in the coffee bean’s journey from farm to cup. During the roasting process, coffee beans undergo chemical changes that affect their flavor and aroma.

Roasting also reduces the bean’s moisture content, making it less prone to spoilage. However, once roasted, coffee beans begin to release carbon dioxide and lose flavor over time.

How Best by Date Affects Coffee Shelf Life

Most coffee bags come with a “best by” date, indicating when the coffee is at its peak freshness. However, this date is not a guarantee of freshness, and coffee can still go stale before or after the best-by date.

How Packaging Affects How Long Coffee Beans Last

Proper storage can significantly extend the shelf life of coffee beans. Conversely, improperly stored coffee will spoil and go stale quite quickly, making it crucial to store the beans correctly.

Here are some of my top tips for storing coffee beans.

• Store in an airtight container to prevent exposure to oxygen.
• Keep the container in a cool, dry place away from light and heat sources.
• Avoid storing coffee beans in the fridge or freezer unless they are in an airtight container, as the beans can absorb moisture and odors from other foods.
