Does Green Coffee Packaging Matter?
Yes, green coffee packaging absolutely matters! Traditional packaging like jute bags exposes your beans to moisture, heat, and light during transport and storage, all of which can damage the quality. These conditions are common at the origin, during shipping, and even at the roastery. To prevent this, we take a different approach.
At BN Pack, we use food-grade packaging solutions like GrainPro, Ecotact, and our own high-quality bags to protect your green coffee beans. Our bags are made from durable, weather-resistant polypropylene with bag-in-bag technology.
This keeps your coffee beans safe, ensuring they stay fresh and free from contaminants. We don’t rely on makeshift storage like plastic sandwich bags or paper bags, even for samples.
We offer green coffee packaging with tamper-proof seals. Once you open the package, just re-sealing the bag properly between roasts will go a long way in preserving the quality of your beans.
How Long Can Green Coffee Beans Last?
Green coffee beans can stay fresh for up to 12 months if stored correctly. Proper airtight or multi-layer packaging can extend this lifespan even further. Keep in mind that the coffee you receive wasn’t harvested yesterday.
Depending on its origin, the beans may be a few months old before they reach you. To know exactly how old your green coffee beans are, refer to a harvest calendar by origin for a clearer picture.

How to Store Green Coffee Beans?
Storing green coffee beans properly is crucial for preserving their quality and flavor. Factors like temperature, humidity, light exposure, air, packaging, and storage location all play key roles. Below are tips to help you store your beans effectively for maximum freshness and longevity.
1. Ideal Temperature for Storing Green Coffee Beans
Store your green coffee beans in a cool, stable environment. Aim for temperatures between 60-70°F (15-21°C). Excessive heat speeds up the aging process and negatively impacts the beans’ flavor. A consistent, moderate temperature ensures that the beans maintain their original characteristics and stay fresh longer.
2. Control Humidity for Fresh Coffee Beans
Humidity is a crucial factor when storing green coffee. High moisture levels encourage mold growth and spoilage. Maintain a humidity level of around 60-65% to keep your beans safe from deterioration. Using airtight or moisture-resistant packaging can help regulate humidity and ensure your beans remain fresh.
3. Protect Your Coffee from Light Exposure
Light can cause oxidation, which degrades the flavor and aroma of your coffee beans. Always store your beans in a dark place, or better yet, use opaque or UV-resistant packaging. Protecting them from light exposure helps preserve the beans’ natural oils, keeping their flavor intact.
4. Minimize Air Exposure to Preserve Coffee Freshness
Exposure to oxygen leads to oxidation, which reduces the freshness and flavor of your beans. To minimize air exposure, use airtight containers or vacuum-sealed bags. This helps preserve the beans’ quality by preventing oxidation and maintaining their optimal flavor profile over time.
5. Best Packaging for Storing Green Coffee Beans
Using the right packaging is key to extending the shelf life of green coffee beans. Opt for multi-layered bags, hermetic seals, or vacuum sealed coffee bags that offer protection from moisture, light, and air. Quality packaging preserves the beans’ freshness and protects them from external factors that can degrade quality.
6. Choosing the Right Storage Location for Coffee Beans
Store your green coffee beans in a clean, dry, and well-ventilated space. Avoid areas that are too humid, too warm, or exposed to direct sunlight. A dedicated storage space ensures that your beans remain free from contamination, mold, and other environmental factors that could affect their quality and taste.
Why Choose Hermetic Bags for Your Green Coffee Storage?
Green coffee beans are highly hygroscopic, meaning they easily absorb moisture from the air. To prevent this, it’s crucial to use airtight packaging and storage methods.
For any coffee roaster or producer, packaging green coffee during shipping and storage is essential to maintaining its quality. You must ensure that the packaging protects the beans from excess moisture, oxygen, and light, all of which can degrade the beans’ integrity and flavor.
Hermetic bags are an excellent choice for storing green coffee. Made from high-strength, multilayer polyethylene (PE), these bags create an airtight seal that protects the beans from moisture and oxygen.
This seal helps maintain the ideal moisture content of between 8% to 12.5%, which is key to preserving the beans’ quality. With zippers or twist-ties, these bags prevent any external elements from entering, ensuring the beans remain fresh.
Exposure to oxygen and light can lead to oxidation, causing the coffee to develop undesirable, woody, and flat flavors. In fact, oxygen levels in green coffee bags should stay at a maximum of 3% to preserve the coffee’s flavor profile and maintain a high cup score. By using hermetic bags, you prevent these negative effects from compromising the flavor and quality of the beans.
At Campos Coffee, airtight hermetic liners are used to store green coffee, whether in standard 60-70kg bags or larger 1,000kg bulk bags. This ensures that external factors do not affect the beans’ quality and helps avoid potential damage like water entering the containers.
For any quality-focused coffee business, hermetic packaging is crucial. It not only preserves the beans during transit and storage but also plays a key role in maintaining the flavor, integrity, and overall quality of the final product.
