Canned coffee (缶コーヒー, kan kōhī) is a pre-brewed version of the beverage, sold ready to drink. It is particularly popular in Japan, South Korea, and elsewhere across Asia, and produced in a number of styles and by a large number of companies. Canned coffee is available in supermarkets and convenience stores,[1] with large numbers of cans also being sold in vending machines[2] that offer heated cans in the autumn and winter,[3] and cold cans in the warm months.
