Abstract
A fully automated cappuccino, latte, and espresso brewing machine which includes a refrigerated milk supply from which milk is drawn by a steam driven venturi apparatus. The venturi subcombination includes independently electrically operated valving for the driving steam, for drawing milk from its supply, and for drawing air, as desired, for foaming the milk in a vortex mixer coupled to the output of the venturi. The valving may be sequential so that with each cycle of use of the apparatus, it is hygienically steam cleaned of all milk residue.
