K-Cups are used with Keurig’s single serve brewing technology to brew a consistently delicious cup of coffee, tea or hot cocoa – in less than one minute. Keurig’s revolutionary K-Cup coffee pack is a plastic container, similar to a coffee creamer, with a coffee filter inside containing perfectly ground coffee beans, tea leaves or hot cocoa powder. http://www.alpinevalleycoffee.com/keurig-k-cups.html
