How To Store Green Coffee Beans In Small Quantities? One of the most difficult aspects of purchasing large amounts of green coffee is ensuring that the beans remain fresh for as long as possible by avoiding exposure to moisture, temperature, air, and light.
Although home roasting has grown in popularity, as has the number of micro-roasters, the necessity for methods for keeping smaller quantities of green coffee has increased.
WHY IS PROPER STORAGE OF GREEN COFFEE IMPORTANT?
Green coffee must be kept properly in order to retain its freshness.
Green coffee, although it may store green coffee beans quality for weeks or months, is still a hygroscopic commodity. This implies it is very sensitive to humidity in the air.
Because green coffee is purposefully dried to the desired moisture level (about 11 per cent or 12 per cent) before shipment, it is critical that it does not absorb any further moisture while being kept. This may wreak havoc on quality and possibly lead to mould growth.
Furthermore, since green coffee is so absorbent, incorrectly kept green coffee may absorb any very strong scents or tastes that may be present nearby.
Finally, keep it away from direct sunshine and heat, which may degrade the flavor and freshness of green coffee.
As a consequence, we know that the crucial occasions when traditionally packaged coffee (i.e. in jute bags) is subject to quality deterioration include inland transit, port delays (the containers are often left at the dock in the sun), and severe temperatures and moisture during transport of goods.
Because these variables are often outside a trader’s or roaster’s control, minimizing their influence is critical.
These elements, though, aren’t only a concern in travel. Even once green coffee arrives at the roastery, purchasers should take care to store their beans cold, dry, low-moisture, and out of direct sunlight.

STORING GREEN COFFEE IN SMALLER VOLUMES
Green coffee is regularly distributed in 60kg sacks across the globe. When we speak about a “bag” of green coffee, it’s quite likely that it’ll be 60kg in size.
In recent years, however, exporters have begun to provide a variety of sizes, including 10kg and 25kg bags and cartons, in order to cater to the burgeoning micro and home roaster markets. These may also be coffees that are a little more scarce or of a better grade.
“Typically, an increase in quality indicates a greater price. As a result, importers and roasters seek to safeguard the value of, for instance, micro-lots, which may cost more than twice the price of a regular coffee.”
Any subtlety lost throughout the transportation process will have an impact on how the coffee is assessed and graded. This implies that there is always the possibility of losing large sums of money if storage is inadequate.
Furthermore, for dealers and roasters, shipping and receiving green coffee samples is part of the purchasing process. The quality of these samples will be critical in making purchase selections. As a consequence, it is critical that it be properly maintained.
It might take months to assess a sample, so ensuring sure it’s properly preserved is critical.
Even if the coffee is maintained at the proper temperature, keeping air away from the green beans is one of the greatest methods to keep them fresh.
STORING ADVICE FOR SMALLER QUANTITIES OF GREEN COFFEE
When keeping samples or small amounts of green coffee, there are a few basic practices to follow. Following these instructions will ensure that the coffee keeps fresher for longer and tastes wonderful once it has been roasted, ground, and brewed.
These are some examples:
- Coffee should be stored in a cool, dry, dark area away from direct sunlight and heat.
- Keep your coffee off the ground by elevating it (by storing it on shelves, for instance)
- Keep it away from any water sources or humidity and in a neutral-smelling atmosphere.
- Make sure it isn’t stored near anything that has a strong odour (such as chemicals or pungent food products)
- However, in addition to these suggestions, the best thing to do is just utilize higher-quality packing.
HOW DOES BETTER BAGS ASSIST PRODUCERS?
Coffee farmers devote a significant amount of time and money to maximizing the potential of their plantations. To completely reflect the quality of their coffee, they must have a reliable system for shipping and storing green beans.
In the past several years, we’ve had a number of roasters and customers question us about vacuum packing. This is due to the fact that when we sell a container, it is usually purchased by an importer, who then distributes it to individual little micro-roasters.
Even if the coffee is of great quality when it leaves the field, long delays at the port might cause the freshness to deteriorate and provide a negative first impression.
Smaller coffee bags are more popular with home and micro-roasters for a variety of reasons. While price, accessibility, and flexibility are all key considerations, the size and physical difficulty of lugging a smaller bag also contribute to its popularity.
Lifting 60kg or more may be unsafe in micro or home roasters with as little as one person on duty at a time.
Because they are tiny roasters, the majority of our clients only make batches of 15kg. For them, the bag size is great, and they don’t wind up opening a bag and leaving it exposed for an extended period of time.
Given the recent growth of the home and micro-roaster market sectors, developing methods for keeping smaller volumes of green coffee has become critical.
Finally, the key concern is freshness. By correctly storing your coffee, you can ensure that your customers’ green beans remain fresh – and that they keep coming back for more.
What Are the Different Ways to Store Green Coffee Beans?
Green coffee beans are porous and hygroscopic, which makes them easy for water to get inside. This means that they are very good at taking in and holding on to water. It will smell and taste like garlic if you store your fresh green coffee beans near garlic.
When most people think of bulk coffee storage, burlap or jute sacks of coffee beans come to mind. Stacks of these bags are seen all the time in pictures of farmers. When you store porous coffee beans in porous bags, they become moister. People on the other end of the spectrum from permeable woven bags are people who use plastic bags. People have a hard time with plastic bags because they get condensation inside of them. In the same way, there are problems with moisture content again This can make the green beans fade and lose their aroma and flavour. Mouldy beans can also happen.
To make the coffee beans too porous or not porous enough, you can package them in two ways: Fortunately, packaging experts keep coming up with new ways to store coffee beans, taking into account the following important factors:
There are different amounts of moisture on the ground.
This is how the temperature is going to be at different times.

The Moisture Levels
A lot of green coffee beans get drier as they go from being harvested to being roasted, so this is how it works: When coffee beans are picked but not yet processed, they have about 50% water in them. It takes about 11 per cent moisture to get the raw beans ready to be shipped by producers. At the International Trade Center, they say this level of moisture is best. Keep in mind that some speciality coffees have different moisture requirements.
As you can see, there isn’t a lot of room for error when it comes to shipping and making beer. It’s safe for roasters to use coffee beans that have been stored in a place where the humidity is stable (about 60%). Mould will form on your beans if the humidity is too high. Lower humidity will make your beans dry out and lose their flavour. Moisture levels are a big problem when it comes to quality control.
Levels of Temperature
As the temperature of the air rises, it can hold more water molecules. Warmer air has more moisture in the air, and cooler air has less moisture in the air. Cool air is better for storing green bean coffee because it’s less likely to get mouldy. Many experts say that beans should be kept at room temperature. Room temperature can be anywhere from 60 degrees Fahrenheit to 77 degrees Fahrenheit, depending on who you talk to about it.
You may have heard of freezing or refrigerating beans. This isn’t very good. The question of absorbing aromas and flavours comes up. Even if you can get rid of the smell and taste, the temperatures are too high at 0 to 40 degrees Fahrenheit.
Levels of light
Most people dry their coffee beans in the sun. This is cheap because it doesn’t need any special equipment. People who grow coffee beans need bright light at this point. This process will bring the moisture level down from about 50% to 11%. At this point, the bean should be done with bright lights. The beans will lose their flavour and aroma if they are exposed to more direct sunlight. Green coffee beans should be stored in a dark place or in an opaque container, experts say.
The traditional burlap and jute sacks are the most dangerous for pests, especially if the beans aren’t dried to the right level. Most pests need water to live, so they are drawn to unroasted coffee beans. Coffee weevils can cut the weight of a coffee bean by one-third in six months. psocids can also get into the beans of coffee. These bugs make their way into the coffee bean. Most of the goods coming from developing countries are treated and certified to be free of pests before they are sent. It doesn’t matter how they get to the warehouse. Even though they don’t have any extra people on them, pests can get into the storehouse and stay.
The quality and quantity of the beans can go down if they are kept for a long time. For the most part, if you keep green coffee in a stable environment that’s cool, dark, pest-free, and stable, you can keep it for up to a year. Central or South American, Indonesian, or Indian coffee beans will be 3 to 4 months old by the time you get your beans. It can be up to a year since your beans came from an African country before you get them. Make sure you think about these times when you plan to store things.
Options for keeping and packaging
Burlap or jute sacks of coffee beans have a lot of people interested because they are cheap and environmentally friendly. Pests, heat, or humidity damage could cost the producers and the people who make and sell the coffee, so they can’t lose a lot of money. Containers that have many layers of high barrier plastic help keep the storage environment stable. There are packaging companies that are making these kinds of containers When you think about the best ways to store your bean green coffee, think of them as fresh plant products. Every type of fresh plant food has a different flavour or quality because of things like light, heat, air, moisture, time, and pests.
How to preserve ground and roasted coffee beans after roasting
If you have time, you can buy coffee beans and roast them yourself, this is the best way to get the perfect coffee flavour. However, the way to preserve coffee beans also needs its own rules. Pure coffee always has more aroma than processed ones because they still retain the original flavour of the coffee.
How to keep powdered coffee?
We already know that the enemies of coffee are moisture, temperature, air and light. Whether it’s coffee beans or ground coffee, these factors should be avoided. Coffee after roasting should be stored in an airtight container in a cool, dry place.
Until the coffee powder is used up, roast the coffee beans again, so this will help the coffee to be preserved longer and keep the flavour better. Similar to powdered coffee, for coffee beans after roasting, you should never put them in the refrigerator, even if they are stored in a box, the smell of food from the refrigerator will also be able to follow the box to make coffee quality. significant losses.
Should store coffee in plastic or glass containers?
Why should you not choose a plastic box to store coffee? Very simply, coffee is easy to smell, but plastic containers are made of chemical compounds and can cause a very unpleasant plastic smell for coffee. Therefore, we should not use plastic for coffee to avoid reducing the aroma and quality of coffee beans as well as coffee powder.
Coffee containers are usually glass containers, there are boxes with tight lids. If possible, use a dark box to keep the coffee out of direct sunlight.
keep the good coffee powder
The glass box can help the seeds avoid the smell, but the glass box is quite expensive
Sometimes when buying ground coffee, or coffee beans, they are usually stored in bags or packages after they have not been used up, you absolutely do not let them continue in the bag but should switch to a container in this way for better preservation.
If possible, you can vacuum all bags of coffee beans. This will help the coffee to be preserved longer and not lose its original taste.
