A single unit milk dispenser for producing hot frothed milk or hot non-frothed milk uses milk and steam. A reservoir supplies milk via an adjustable valve to a first chamber. For supplying frothed milk, steam is issued from a first steam outlet nozzle and mixes and froths with the milk in the first chamber and in an expansion chamber before being dispensed out of a collection chamber. For non-frothed milk, steam supplied from a second steam outlet nozzle is released to mix and swirl around with cold milk fed from the reservoir into the collection chamber. The rate of flow of milk out of the reservoir is normally adjusted for the two mode of operation, which mode is simply otherwise determined by which nozzle supplies steam, by turning a steam supply selection knob.
