Abstract: A method is provided for cooling a beverage in a container, the container being provided in contact with a cooling contact body thermally conductively coupled to a cooling element. The method comprises operating the cooling element and obtaining an ambient temperature of the environment outside the container and the cooling contact body. Based on the ambient temperature, a cut on temperature is defined and a temperature value indicative of a temperature of the beverage is obtained. The cooling element is operated if the temperature is larger than the cut on temperature until an end criterion is met. A higher ambient temperature may require more cooling of the beverage to ensure the temperature of the beverage is maintained between acceptable boundaries. A higher environmental temperature, requiring more cooling, means faster switching on or off. By using a switch on temperature based on the ambient temperature, more efficient cooling may be established.
