The invention describes a sorption self-cooling beverage device which cools its beverage instantaneously, and no heat conducting surfaces are required. A chamber containing a beverage is mixed with a consumable refrigerant such as water. The boiling point of the beverage-refrigerant mixture is lowered to freezing temperatures by an air vacuum. The vapor generated by the boiling beverage-refrigerant mixture is conducted to another chamber containing a desiccant, which removes the vapor. A barrier permeable to water vapor but not to desiccant particles is placed between the beverage-refrigerant and desiccant chambers to prevent a contamination of the beverage by the desiccant. A water absorber is placed in the desiccant chamber to prevent a contamination of the beverage with liquid which may have entered the desiccant chamber from the beverage chamber.
