A device (3) for metering a base liquid and mixing this base liquid with a diluent to prepare a food product, has a connecting portion for connecting it with a container (4) containing the base liquid, the device (3) including: a diluent inlet (71), a mixing chamber (80) for mixing the base liquid with the diluent. An actively controlled air inlet is provided for selectively having ambient air enter the device and guiding it to the container (4). A controller is provided for selectively metering the base liquid into the mixing chamber and for selectively enabling an air flow through the air inlet only during periods when no base liquid is metered into the mixing chamber.
