At this critical phase, storage conditions play a pivotal role in either preserving the beans’ characteristics or allowing them to deteriorate gradually. Green coffee is not merely a raw commodity; it is a living agricultural product, sensitive to environmental factors such as temperature, humidity, light, and oxygen. Any imbalance in these conditions can result in flavor loss, the emergence of off-notes, and ultimately, a decrease in the market value of the product.

One of the most significant factors influencing coffee quality during storage is temperature. It is recommended that beans be stored at moderate and stable temperatures, typically between 15°C and 20°C. This range helps slow down internal chemical reactions and prevents the degradation or evaporation of aromatic oils. Frequent fluctuations in temperature can cause the beans to expand and contract, leading to gradual moisture loss and deterioration of their internal structure.

Humidity is another crucial element in the storage equation. Beans require an environment with balanced relative humidity, generally between 50% and 60%. When surrounding humidity drops too low, beans tend to overdry, losing their flexibility and becoming more brittle during roasting. Conversely, if humidity exceeds 65%, beans become prone to mold and fungal growth, which can lead to unpleasant “cardboard” or “musty” flavors, negatively impacting the final cup quality.

Another important concept in coffee storage science is "water activity," which refers to the amount of free water available for biological reactions within the bean. It is advisable to maintain water activity levels between 0.45 and 0.55—sufficient to retain the bean’s pliability while preventing microbial growth and spoilage.

Storage duration itself also determines whether beans will remain fresh and vibrant or gradually lose their flavor profile and eventually be classified as aged coffee. Generally, it is recommended not to exceed 12 months of storage, particularly if beans are not packed using airtight packaging or vacuum-sealing technologies.

Packaging quality is equally critical. Traditional jute bags allow the beans to breathe but can also absorb moisture from the environment and transmit external odors. Modern solutions such as GrainPro bags or vacuum-sealed packaging offer a robust barrier against oxygen and moisture, significantly extending the shelf life of green coffee without compromising its qualities.

No discussion of green coffee storage would be complete without emphasizing the importance of protecting the beans from direct light and oxygen exposure. These two invisible forces accelerate the breakdown of aromatic oils and alter the bean’s chemical composition, ultimately degrading the flavor quality. Therefore, beans should be stored in dark, opaque, and airtight containers, placed on elevated shelves away from damp floors.

In specialized warehouses and green coffee trading companies, stringent systems are in place to monitor storage conditions. These include installing humidity and temperature sensors and adhering to strict inventory rotation schedules based on the "First-In, First-Out" principle. Every incoming batch is meticulously documented, noting receipt dates, moisture content, and packaging type, allowing for comprehensive traceability and consistent quality control until the beans reach the client.

Investing in green coffee storage is not merely a logistical task—it is a strategic commitment to ensuring that a high-quality product reaches roasters and customers, thereby protecting the supplier’s reputation and securing market trust. By maintaining optimal storage conditions, companies ensure that they continue to offer coffee that authentically reflects its rich agricultural origin and maintains the quality that begins with storage and culminates in the cup.
