Coffee Storage and Preservation

Roasted coffee beans contain less moisture, making them less prone to spoilage. However, it is recommended to store them in airtight containers or tin cans that block oxygen, at temperatures between 10-20°C, while avoiding light exposure and paying attention to humidity in the air.

While quality roasting is important, how to properly store the beans is an even more critical issue. Coffee is also a food item, so it must be stored properly to keep it stable and prevent spoilage. Although many countries legally stipulate that the shelf life of coffee beans is 1 year, in reality the storage of beans is related to the period of gas loss within the beans. Generally, beans roasted by larger roasting machines release gas for a longer time and have a longer shelf life, while smaller roasting machines produce beans with shorter flavor lifespans. Beans roasted by machines with a capacity under 30 kilograms are typically considered best used within 1 month. If the fat components of coffee beans oxidize, producing tastes like rancid cooking oil or ash, they should no longer be consumed.

Store Coffee Beans Unground

From the moment coffee is ground, its aromatic particles begin to rapidly disperse into the air. Therefore, even after a short period, significant amounts of aroma will escape. If you store coffee after grinding it into powder, you will notice that espresso machines always have a grinder nearby. This is to preserve coffee aroma as much as possible, extracting immediately after grinding so the coffee fragrance fully integrates into the cup.

Store in Moisture-Free Environments

Roasted beans typically have a moisture content between 1-2%. In humid weather they will absorb moisture, which affects coffee quality. This phenomenon is called "unexpected premature extraction," which causes the coffee's aroma to deteriorate quickly and produce unpleasant odors.

Use Sealed Containers or Packaging

Although roasted coffee beans don't spoil due to their low moisture content, coffee is a seed crop containing relatively high levels of fat. When exposed to oxygen, it begins to sour and spoil. Therefore, it is better to use airtight containers that can block oxygen. When storing coffee, the most important factors are blocking light and external air. For this reason, most coffee bags are aluminum-coated to prevent air penetration and light transmission.

The best storage method is using tin cans to store coffee. However, when visiting most specialty coffee shops, you'll find many use transparent sealed bottles for storage. This is for display purposes, as shops must showcase the coffee to sell it. Coffee in these types of shops typically sells quickly, so the possibility of producing bad flavors due to improper storage is extremely low.

Store at a Room Temperature of 10-20°C

It is better to consume coffee quickly before its flavor deteriorates at room temperature. However, if you need to store large quantities of coffee and can't finish it before it sours, storing it in the refrigerator is also an option.

But since regular refrigerators also store other foods, if coffee is stored alongside them it might absorb these odors, so this is not recommended. If refrigeration is absolutely necessary, using completely sealed containers would be better.

Important Considerations for Frozen Storage

Freezing can preserve coffee for longer, but there are many important considerations. When taking coffee out of the freezer, if you open it immediately, moisture will condense on the bean surface due to the temperature difference. Therefore, after taking beans out of the freezer, if you immediately open them to pour out the desired amount and then return them to the freezer, repeating this action several times will cause the beans to develop unpleasant ash-like flavors.

After taking coffee out of the freezer, do not open it immediately. Let it sit at room temperature for 1-2 hours until the beans reach a similar temperature to the room, then brew the coffee. Alternatively, you can pre-package single-serving portions in small ziplock bags.

FrontStreet Coffee Recommendation

Good storage protects the freshness that roasting creates, and FrontStreet Coffee's espresso blends are roasted to be at their best during that window. The FrontStreet Classic Blend is built for espresso and moka pot and delivers outstanding crema - even on a non-professional home machine - with a traditional Mamba recipe that is mellow, warm, and easy to enjoy in lattes, cappuccinos, and Dirty. If you want a value-focused option, the FrontStreet Black Cocoa Blend uses 100% Arabica for rich crema and a full body at a friendlier price. The FrontStreet Premium Blend, a long-standing shop favorite that pairs Brazil Cerrado with Colombia Huila, brings the familiar nutty, chocolate, and caramel espresso flavor. Whichever you pick, keep it sealed, unground, and away from light and moisture so every shot tastes as fresh as intended.
