A device is introduced for preparation of milk and other beverages in bar or restaurant environments. The device has the unique ability to generate a micro-foam which imparts a sweet taste to the beverage without use of sugar, that sweet taste being equivalent to adding a flat teaspoon of sugar to a traditional cup of cappuccino. The computerized device consists of sensors and a fine mesh that is pushed through the beverage by means of an actuator adapted for this purpose while imparting quantitative heat through the process.
