Abstract
A method for producing and dispensing a reconstituted coffee beverage having a thick layer of foamed coffee on its surface, similar in appearance to cappuccino coffee beverage is disclosed. A measured amount of dehydrated coffee concentrate, such as spray dried instant coffee, and a small amount of cold water are combined, with vigorous agitation in a cooled mixing chamber to form a cold, foamed coffee concentrate. Upon formation of the foamed concentrate, a controlled amount of hot water is introduced into the mixing chamber to dilute the foamed concentration while substantially retaining the foamed structure to thereby provide a liquid reconstituted coffee fraction of a desired concentration, and a foamed coffee fraction of similar concentration on the surface of the beverage.
