As a coffee roasted coffee beans, you will often have to pay close attention to the quality of coffee beans, cupping many different types of samples. And then is identifying the ideal roasting profile, try several other options. All of this is to discover how to bring out the best coffee flavor. So what if you did all of this but then storing roasted coffee disappointed home espresso machine you? Or you can’t move your coffee as quickly as planned. And then your coffee breaks down over time? Let’s find out How To Store Coffee After Roasting?
Roasted coffee is easily influenced by many factors surrounding it—temperature, light, humidity, and above all, oxygen. Proper post-roasting coffee preservation will help prolong the freshness and retain the characteristics of the coffee for as long as possible. From there, your customers can enjoy the taste of coffee to the fullest.
Why Is It So Important To Store Coffee After Roasting?
Show an average person you meet on the street the un-roasted coffee. You’re surprised they didn’t realize it was coffee. Because it is steel gray and does not have the aroma of coffee that we often see, it smells of vegetables. Such as dried peppers.
The roasting process produces the aroma and taste that we often associate with coffee. It could be chocolate, caramel, or floral scents. But when coffee beans change logically, so does their chemical composition.
One of the most critical transformation processes is the decomposition of sugar to form different compounds. That includes carbon dioxide. Carbon dioxide is trapped inside the coffee beans. After roasting, it will gradually escape. That is called the degassing process. Degassing is a crucial transformational process for coffee, especially if you want to make an espresso. Because if there is too much carbon dioxide in the coffee beans, they will interfere with the extraction process.
However, when coffee loses carbon dioxide, it also tastes pale. In The World Atlas of Coffee, James Hoffman says that two changes occur when coffee is rancid. The first is the gradual loss of compounds that create the aroma and taste of coffee. That is inevitable whether we try to delay the process.
The second change is due to humidity and oxygen. Exposure to moisture and oxygen will cause the coffee to burn. This change is easier to control because we can prevent oxygen and water from coming into contact with coffee beans.
In other words, roasted coffee is even more vulnerable to loss of scent when exposed to moisture and oxygen. That makes storing and preserving them more critical than ever.

Selection Of Quality Packaging
Many roasters turn to foil packages and sealing when delivering coffee to customers. This method is to avoid light, oxygen, and moisture affecting coffee. These packages also often have valves to release carbon dioxide gas. Facilitate the initial degassing process.
Some roasters prefer to preserve coffee beans in packages that can be pulled back. Such as those with zip locks. That will allow the customer to close after each use. Make sure to limit your exposure to oxygen.
Others use unsealed craft bags. However, this type of packaging is environmentally friendly and often affordable. But they can’t remove oxygen effectively. Therefore, the coffee stored in this type of packaging will quickly spoil.
Store Roasted Coffee In The Right Place
In addition to the correct type of packaging, coffee also needs to be stored in a suitable place. Even zip-locked banknote bags can’t protect the coffee from high temperatures—store coffee in dark cupboards or warehouses, where excellent is usually the best option.
For home brewers, coffee containers are becoming increasingly popular. People make coffee containers of stainless steel. Therefore, they are resistant to impact heat resistant. However, most coffee containers usually store a small amount of coffee. So they become a better option to use at home, instead of coffee shops.
Before sending coffee to customers, roasters will sometimes also store the coffee in large-sized boxes. However, the quality of each type is different. And, of course, they are pretty large and heavy. They can’t be easily moved when needed. And neither is it a substitute for regular bags.
There are options for you to store and preserve your coffee heavy roasting providing varying degrees of coffee protection. But one thing hasn’t changed. It is roasted coffee that will quickly lose its quality. They will become rancid in a matter of days or weeks.
Options On How To Preserve Roasted Coffee Beans
Testing of Blue Bottle and GrainPro
Although roasted coffee is more susceptible to spoilage than coffee beans, the factors that need to be resisted are the same: temperature, light, humidity, and oxygen. With coffee, sealed packaging is often used to fight moisture, antioxidants, and insects.
So Charlie Habegger and Carly Ahlenius from Blue Bottle Coffee’s Green Coffee Division partnered with GrainPro. The two began testing the impact of sealed packaging on the long-term storage of roasted and coffee fillings.
GrainPro is known for its closed packaging solutions for coffee beans and other agricultural products such as corn and rice. However, the company aims to solve many of the problems manufacturers and roasters face, from tarps to sanitary coffee storage drying to pads when transporting coffee inside trucks.
Blue Bottle conducted the test from May to September 2018. The coffee they use is Rwandan Nyanza Kirezi from the 2017-2018 harvest. For freshly roasted coffee analysis, coffee beans are preserved for 24 hours roasting in three different ways. Give them time to de-de-grease first. These are the types of packaging that were used during the test:
- Compostable paper bags (Blue Bottle’s standard storage method) are opened once a month for sampling.
- GrainPro’s 15kg Ultra-Hermetic zipper bag is opened once a month for sampling.
- GrainPro’s 15kg Ultra-Hermetic zipper bag, sealed during the five-month test
The quality of coffee is analyzed according to the SCA tasting process.
With compostable paper bags, cupping scores have dropped from 86 to 79 in five months. It dropped the first three points between May and June 2018. It then fell another 1.75 points between June and July. And then gradually decreased to the final point of 79 in September 2018.
When it was store in an Ultra-Hermetic bag and opened once a month, the score dropped from 86 in May to 80.88 in September 2018. Its flavor varies from caramel sweetness, dried strawberries, and lemon to apricot and apple flavors.
Finally, for the closed GrainPro bag, the score dropped from 86 to 82.88. In May 2018 since, the samples had apricots, floral, and citrus flavors. In September 2018, coffee’s had tones of brown sugar, which tastes like fruit and chocolate.
Five months is a lot longer than coffee should store specialty roasted coffee tea. However, changing the packaging can extend the shelf life of coffee beans a lot. For example, sealed bags may not currently be the standard preservation method for dental coffee roasts. But they protect against moisture and oxygen.
So, what’s the best way to store coffee after roasting? Stay away from moisture, light, heat, and oxygen. Ultra-sealed bags are an excellent way to increase shelf life and slow down the fading process of specialty beans. Solutions like this can add flexibility to roasters in the third wave, especially for small businesses that may not calculate consistent orders by week.
No matter what type of packaging you’ve chosen to store your coffee in-store roasted coffee, there are some things to pay attention to: allow the green coffee beans time to degass, then seal it. Open the bag as little as possible. And finally, keep them in a cool, dry place. And to make sure your customers enjoy the best coffee, consider sharing these tips with them.
