Roasted coffee starts to stale soon after the resting/degassing period so storage is important. We sell 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 do not sell bags or containers wholesale or fill orders with bags or containers only! I don't like imposing this rule but we are trying to serve our home-roasting customers by offering bags, and not to become a bag supplier. If you place an order for all bags and/or containers - we will notify you that we are canceling the order and will not be able to ship it. There are other bag suppliers on the net - we are not one of them!
