Ideally, coffee bean will be roasted shortly before they are used to ensure optimal flavor and freshness. If you can’t buy your beans in freshly roasted batches regularly, then an airtight container is the best thing you can do in terms of bean storage. The BeanVac Coffee Bean Canister is even better. The canister has a built-in battery powered pump that sucks the air out of the container – meaning that your beans will remain fresher, longer. The pump automatically activates whenever there is a pressure change in the canister, so you can take beans out and the vacuum kicks into action when you shut the lid again.
