A method and apparatus for forming a beverage. Movement of a brew chamber may automatically enable the provision of beverage precursor liquid into a reservoir in a brewer, which is then used (heated or not) to form a beverage. For example, closing of the brew chamber may cause a lid for a water reservoir to be fully opened or otherwise permit movement of the lid to allow access to the reservoir, allowing a user to provide water into the reservoir. The reservoir lid may open with an abrupt action, causing attention to be drawn to the reservoir lid. In another arrangement, closure of the brew chamber may cause actuation of a baffle, pump, valve or other device to provide a suitable amount of water to a reservoir for beverage formation. In another arrangement, opening of the brew chamber may cause the reservoir lid to be automatically and simultaneously opened with the brew chamber.
