Even instant coffee is available and it has been dried into soluble powder or freeze dried into granules, which can be quickly dissolved in hot water for consumption.

Many vending machines typically sell a number of varieties of canned coffee, available both hot and cold. Liquid coffee concentrate is used in large institutional situations where coffee needs to be produced for thousands of people at the same time.
