There are various ways roasters store coffee in plastic bins. Some use plastic food storage containers with lids, while others use plastic garbage bins or trash cans, sometimes lined with dark garbage bags. The size of the bin or container varies depending on the volume of coffee being stored, with options ranging from small plastic pails to large brute bins or trash cans. Some roasters also use nitrogen flushing or sealing to extend the freshness of the coffee. The storage method can depend on the scale of the roaster's operation, with larger roasters using stainless steel containers or silos, and smaller roasters opting for plastic bins or containers.

Roasted coffee is stored in Brute bins before bagging
Some roasters use plastic garbage bins to store roasted coffee, which can be left for 1-3 days before bagging. Larger roasters may use freezers to store roasted beans, but only for a short period before bagging, typically 3-4 days. Freezing coffee is generally not recommended, but some people find it helps to preserve the flavour for up to four weeks. When freezing, it is important to use a sealed plastic bag with most of the air removed and to place the bag inside a brown paper bag to block incidental light.
Some roasters also use nitrogen flushing to extend the freshness of the coffee. For larger quantities of roasted coffee, plastic bags are stored in straight-up plastic totes. One user on a coffee forum mentioned that they store their green coffee beans in burlap bags on pallets, while another user recommended using USDA-approved food storage containers for roasted beans.
Overall, it seems that there is no one-size-fits-all approach to storing roasted coffee, and different roasters may use a variety of methods depending on their scale, resources, and personal preferences.

Plastic bins should be white, as this is food safe
When it comes to storing coffee, various methods are used by roasters, including the use of plastic bins or containers. While plastic bins can be utilised for coffee storage, it is important to prioritise food safety. This is where the recommendation to use white plastic bins comes into play.
White plastic bins are considered food-safe for storing coffee and other food items. This preference for white bins stems from the fact that they are specifically designed for food storage and meet the necessary standards. In the United States, the term "food-grade" signifies that a material has undergone extensive testing by regulatory agencies like the USDA. The testing evaluates how the material interacts with the food's composition and how it fares under different storage conditions, including temperature fluctuations. White plastic bins, when certified as food-grade, ensure that the colour, odour, and taste of the coffee remain unaffected.
The use of white plastic bins is particularly emphasised by roasters to prevent any potential contamination. Coffee, especially roasted coffee beans, can be sensitive to its storage environment. By using white plastic bins, roasters can avoid issues such as odour absorption or chemical leaching, which could alter the flavour and quality of the coffee. White bins also help maintain the freshness of the coffee beans by providing a neutral storage option that does not introduce external odours or flavours.
Additionally, white plastic bins designated for food storage are less likely to introduce harmful chemicals into the coffee beans. This is a critical consideration, as some plastics may contain substances that could be detrimental to human health if they leach into the food. White bins designed for food storage are manufactured with this purpose in mind, reducing the risk of chemical contamination.
While white plastic bins are recommended for food safety, it is worth noting that some roasters opt for alternative solutions. Stainless steel containers, silos, and even freezer storage are also utilised by roasters to preserve the quality and freshness of their coffee beans before they are bagged and delivered to consumers. Each method has its advantages, but the overarching goal is to ensure the coffee beans remain in optimal condition.

Green coffee beans are stored in burlap bags on pallets
Green coffee beans are typically shipped in burlap bags, which are inexpensive and easy to manufacture. However, these bags offer little protection during shipping and storage, as they are highly susceptible to moisture absorption and provide minimal protection against pests and environmental changes.
To extend the shelf life of green coffee beans, it is recommended to transfer them from burlap bags to GrainPro bags or sealed containers for long-term storage. GrainPro bags provide high-barrier protection while allowing the coffee to breathe, preventing moisture fluctuations and cross-contamination. For smaller quantities, food-grade containers with tight-fitting lids and one-way valves are also suitable.
When storing green coffee beans, it is essential to keep them away from direct sunlight and maintain proper air circulation to prevent moisture buildup and potential mold growth. Stacking the burlap bags on pallets or warehouse racking ensures they are not resting on the floor, maximizing vertical space and enabling easy tracking of stock using the "first-in, first-out" method.
Additionally, pest control is crucial in maintaining the quality of green coffee beans. Regular inspections of bags and storage areas, as well as maintaining a clean environment, are essential to prevent pest infestations. Overall, with proper storage conditions, green coffee beans can retain good aromatic and physical qualities for up to one year after harvest.

Roasted coffee can be stored in plastic bags inside paper bags in the freezer
Storing roasted coffee beans can be a tricky task, as they can quickly lose their freshness and absorb moisture and odours. It is recommended to use the coffee beans within 72 hours of roasting to ensure maximum freshness. However, if you are unable to use them within this time frame, storing them in the freezer can be an option.
Firstly, it is important to note that roasted coffee should not be stored in paper bags alone, as these bags do not provide an adequate barrier against moisture and smells. Paper bags can be used if they have a liner and are placed inside a resealable freezer-quality bag or airtight container. This helps to protect the coffee beans from absorbing moisture and odours from other items in the freezer.
When storing roasted coffee in the freezer, it is best to use an airtight container or a sealed plastic bag. The plastic bag should have most of the air removed to prevent the coffee from absorbing moisture. The sealed plastic bag can then be placed inside a brown paper bag to block incidental light when the freezer door is opened.
It is worth mentioning that storing coffee in the freezer can be a controversial practice. Some people believe that freezing coffee alters its taste and that the coffee should be consumed within a week to maintain freshness. Additionally, it is important to let the coffee beans thaw to room temperature before opening the bag and brewing to prevent condensation.
Overall, while storing roasted coffee in plastic bags inside paper bags in the freezer can help extend its freshness, it is important to follow proper storage practices and consume the coffee within a reasonable timeframe.
