Abstract: A method for producing a cold mixed beverage made of milk and an acidic component having a denaturing step of the milk is disclosed. The milk is heated to a denaturing temperature TDENAT that is in a range of 72° C. to 155° C. prior to mixing with the acidic component and is maintained at the denaturing temperature TDENAT for a denaturing period tDENAT and then the denatured milk is mixed with the acidic component. The mixture is heat treated to increase the shelf life. The mixture is heated to a temperature THALT which is in a range of 63° C. to 155° C., and maintained at the temperature THALT for a heat treatment period tHALT. The heat-treated mixture is homogenized at a homogenizing pressure Phom which is in a range of 75 bar to 275 bar, and then cooled to a temperature that is in the range of 4° C. to 25° C.
