Why Your Green Coffee is Aging Faster Than You Think: The Science of Shelf Life

Like any other agricultural or food product, green coffee beans have a shelf life as well. It’s nothing but the optimum amount of time in which the green coffee beans remain fresh, after which their quality begins to degrade. Well, for thousands of years, the life cycle of green coffee beans has been spoken about. However, lately, what has taken over the conversations is how and why the green coffee beans are ageing rapidly, and the science behind that. With this blog, let’s understand what is causing green coffee beans to lose their quality faster and how hermetic coffee packaging, like that of Ecotact, can safeguard the freshness and quality of green coffee beans for an extended period of time.

Understanding Green Coffee Beans

Green coffee beans are the raw seeds of coffee cherries that have yet to be roasted. The entire taste and quality of coffee is captured within these raw seeds. Once the cherries are harvested from coffee trees, depending on the coffee’s origin, they are processed in several ways. What processing leads to is that the fruit of the coffee cherry is stripped away, leaving only the green coffee beans. While there are various methods of processing, each method contributes to the final taste. But before one enjoys that perfect cup of coffee, the green coffee beans need roasting. It brings out their aroma, acidity, and flavour! And since all the potential taste and flavour lies in the green coffee beans, it's important to know what causes them to age and lose quality. This is where good green coffee bean bags make all the difference in keeping them fresh.

Factors Affecting the Ageing of Green Coffee Beans

Green coffee beans are susceptible to a number of factors during transit and storage, such as:

1. Temperature:

Green coffee beans cannot handle temperature swings well. Abrupt changes between hot and cold can stress the beans, leading to moisture loss and internal changes. Over time, this damages their structure and takes a toll on their flavour and overall quality.

2. Oxygen:

Exposure to oxygen can make green coffee beans lose their quality. An oxidation process takes place once beans come into contact with air. This leads to the breakdown of key compounds responsible for flavour and aroma. Eventually, it comes to stale, flat-tasting coffee, even before roasting.

3. Moisture:

Moisture or humidity might cause degradation of green coffee beans. A high level of humidity can cause the beans to reabsorb water. It disrupts their internal balance and promotes mold growth. Low humidity levels, on the other hand, can result in brittleness and loss of vitality.

4. Light:

Too much sunlight can speed up how quickly green coffee beans age. It accelerates oxidation, which breaks down the delicate compounds that give the beans their signature flavour and aroma.

5. Packaging Material:

The packaging type plays a huge role in preserving the green coffee beans. Traditional packaging bags are generally breathable and hence can let in moisture and oxygen, and accelerate ageing. So what is required here is the high-barrier packaging, like Ecotact multi-layer hermetic coffee packaging bags. These Ecotact bags can significantly slow down deterioration.

How Ecotact Can Keep Your Green Coffee Beans Fresh?

Ecotact has been preserving green coffee beans, cacao beans, and any other grains for over 2 decades. Present in 50+ countries and across 6 continents, Ecotact offers eco-friendly coffee packaging that is 100% reusable and recyclable. With 9-layered hermetic packaging, Ecotact bags keep the aroma and moisture level maintained. Being tolerant to high levels of temperature (-30 degrees C to + 90 degrees C), Ecotact bags are hydrocarbon-free and highly resistant to oil and solvents. With extra-clear transparent packaging, these hermetically sealed coffee bags increase the shelf life of green coffee beans without any use of pesticides and insecticides.

FAQs

How quickly can green coffee lose quality under poor storage conditions? 

The coffee quality begins to decline after two months of exposure to oxygen and moisture and high temperature. The coffee develops stale or flat flavors while its aromatic properties and sweetness decrease over time. 

Why do some green coffees age faster than others? 

Different coffees age faster because their moisture content and processing method and the climate where they were grown all influence their aging process. Beans from humid regions or with higher moisture levels will oxidize at a faster rate while different processing methods will produce different effects on how coffee beans react to storage conditions. The natural factors that affect coffee storage lead to different freshness loss rates between two coffees that have been stored under identical conditions. 

Is hermetic packaging effective during long shipping and storage periods? 

Hermetic packaging provides protection for green coffee during extended shipping and storage periods through its ability to prevent temperature and humidity changes and outside air contact. 

Why is oxygen control important in green coffee storage? 

Oxygen speeds up oxidation. This oxidation process destroys the flavor compounds present in green coffee. The process of reducing oxygen exposure. This process helps slow down the aging process. It enables storage and transport processes to maintain the quality of beans. 

What role does Ecotact hermetic packaging play in preserving green coffee quality? 

The Ecotact hermetic packaging system protects stored products by preventing both oxygen and moisture from entering the package, which creates optimal storage conditions that decrease product deterioration while preserving the quality of green coffee throughout extended periods. 

Can green coffee age even in controlled warehouses? 

Yes. The presence of oxygen without proper control measures will result in green coffee losing its quality through the entire period of storage which exists at controlled warehouses. The bags will experience oxidation when storage conditions change or when the bags remain unsealed. The warehouse appears stable yet its operations cause gradual deterioration of aroma and flavor and total freshness. 

How does shipping duration impact green coffee shelf life? 

Shipping duration plays a major role in green coffee shelf life. The extended transit period causes coffee beans to experience more temperature fluctuations and humidity variations and physical handling throughout their journey. The factors increase oxidation risk and moisture damage risk which results in faster aging and flavor loss before the beans reach the roasting process. 

What storage conditions best preserve green coffee long-term? 

The long-term preservation of green coffee requires storage in environments that maintain constant temperatures while restricting oxygen and moisture access. This means storing it at a cool, consistent temperature, avoiding humidity changes and using protective, high-barrier packaging to prevent air and moisture from entering. The conditions of the storage environment enable the coffee to maintain its aromatic and flavorful characteristics for an extended period.
