A multi-layer plastic bag with a gas barrier. The bags have been shown to extend the flavor life of the coffee significantly over storage
Green coffee can be stored much longer than roasted coffee: Roasted coffee starts to lose its aromatics in 10 days after roasting. Green coffee can be stored months... in jute or burlap bagsBurlap bags are the traditional container in which coffee is transmitted. Burlap is cheap, but long storage in burlap bags may result in a characteristic "baggy" defect taste.:....: A multi-layer plastic bag with a gas barrier enabling coffee”to build up a modified atmosphere, similar to the principle of the Cocoon” (quoted from the GrainProA multi-layer plastic bag with a gas barrier. The bags have been shown to extend the flavor life of the coffee significantly over storage in jute or burlap... literature). The bags can be used with any kind of commodity, and in tests using coffee, the bags have been shown to extend the flavor life of the coffee. We started using them extensively in 2008 to store delicate coffees and have found them to work very well. It means that we can buy more coffee at the peak of the season, when the best coffee is available, and then hold it in GrainPro for a few months with no flavor loss. In our coffee reviews, when we indicate GrainPro arrivals we are saying that, independent of the arrival month, the coffee is being stored to optimize freshness. For example, ordering a Costa RicaCosta Rican coffee is typically very clean, sweet, with lots of floral accents. hey are prized for their high notes: bright citrus or berry-like flavors in the acidity,... in Decemeber that arrived in jute bags in June formerly meant the coffee was on it’s last legs, and might be showing some age in the cup flavors. Last year, we tapped into GrainPro shipments that arrived in June the following February and they were spectacular, with no indication of age in the cup flavor!
These bags are for resealable safe storage of dry commodities. The bags act as a gas and moisture-proof barrier which guards against the ingress of water vapor, while retaining low Oxygen and Carbon-Dioxide levels created by the respiration of the commodity. They are made of tough, multi-layer plastic with gas barrier between layers of PE 0.078mm thick material. They are sealed using tie-wraps and placed inside the large jute bags of coffee in our warehouse.
