Once coffee is ready for export, it is packed in polyurethane bags, called Grain Pro. These bags are sealed, and help to keep out oxygen while the coffee is being shipped, preserving the coffee and keeping it from aging. These bags are then sealed inside of burlap sacs.
Coffee is shipped in burlap sacs. For all of El Salvador, and most of Central America, each sac weighs 69 kg, or 150 pounds.
A 20 foot shipping container holds 275 (69 kg) bags of green coffee, which is approximately 42,000 lbs. The walls and floor of the container is lined with craft paper, and bags are organized by lots.
Containers are loaded onto cargo ships, which take anywhere from three weeks to two months, to reach their destinations around the world. Once the containers arrive at the port, they are unloaded and delivered to each prospective roaster.
