Coffee pods (also called coffee pads) are pre-packaged ground coffee beans in their own filter. In non-English speaking countries like Germany and The Netherlands the word pad is used instead of pod.
A variation, coffee bags, were developed to provide the convenience of instant coffee but maintain the flavor of brewed coffee. Modeled after tea bags, they consist of a gauze bag containing a mixture of instant coffee and finely ground roast coffee, which is to be steeped in hot water for approximately five minutes.
