Roasted coffee starts to become stale soon after the resting/degassing period has passed, so proper storage is important. We sell several types of bags, and tins with valves for degassing and keeping out the oxygen. We sell cotton bags for green coffee, though green coffee also stores well in the plastic bags we ship them in. For more information: green coffee storage and roasted coffee storage. *Please note: we are not a bag wholesaler. If you need a large quantity of bags, just contact us and we would be happy to share some affordable options with you.
