These test tubes are perfect for freezing single doses of your favourite coffee beans, they fit around 20g of coffee and can be reused over and over to safely store your beans in the freezer.

Whether you are storing coffee for a month, year or longer this system of storing single doses of coffee beans in the freezer can be a fantastic alternative to vacuum sealing, the 20g capacity is ample enough room for 1 dose of filter or espresso beans. 

We made these test tubes available as either individual pieces so you can choose exactly how many you need or as a 25 pack.

To keep your coffee beans fresh and tasty for longer, you can freeze them in different ways. The easiest way is to squeeze out any air from the bag of coffee beans and put it in the freezer. But once you defrost them, use them quickly and avoid opening and closing the bag often because it exposes the beans to fresh air. Another way is to vacuum seal individual portions of coffee beans by pre-weighing them, which can be done with vacuum sealing or reusable centrifuge tubes. These tubes prevent air exposure and can be used multiple times. However, they may not always fit the desired amount of coffee beans due to variations in bean sizes.
