A self-heating, ready-to-drink can of Nescafé Original is to go on trial in the Midlands from the end of May. Nestlé's new "hot when you want" coffee will be on offer in retail outlets across the whole of the area at an rsp of £1.19 a can. White with sugar and white without sugar options have been chosen for the trials. Further variants are being planned after the test period. A button on the base of the standard sized 330ml cans activates a quick-lime and water reaction in the inner membrane, heating 210ml of coffee inside. A spokeswoman said: "You can tell by red dye in the base that the heat reaction has not taken place because it disperses when the button is pressed." {{NEWS }}
