A temperature moderating beverage container includes a cup and an insert, the cup having at least one wall. The insert seals against the cup wall and has a main chamber. An exterior wall of the insert together with the wall of the cup defines a temperature moderating chamber in fluid communication with the main chamber. A lid forms an airtight valve seal over the main chamber. The selective admission of air through the airtight valve seal urges a liquid within the main chamber into the temperature moderating chamber. The temperature moderating chamber and the main body are alternately formed within an insert having a vertical partition extending to the lip of the insert. A cap is designed to seat against the lip and with an intermediate gasket afford an airtight seal over the main chamber.
