Major convenience store chains' huge distribution networks for coffee are supported by procurement from trading companies, but these primarily consist of commodity coffee.
Not only in convenience stores, but also in the regular coffee, instant coffee, and canned coffee sold in supermarkets, as well as much of the coffee served in cafes and coffee shops, all are commodity coffee.
Currently, the price of commodity coffee is determined by the New York Mercantile Exchange and, for some Robusta varieties, the London Mercantile Exchange.
