A controlled pourer that may include a locking mechanism for locking the controlled pourer to a bottle; a communication module; a flow control mechanism that is configured to control an output of fluid, during a liquid consumption iteration, from the bottle under a control of one or more commands received by the communication module; and a flow meter for monitoring an amount of fluid outputted by the flow control mechanism during the fluid consumption iteration. The communication module is configured to output information regarding the amount of fluid consumed during the fluid consumption operation. Once locked to the bottle the controller pourer prevents a bypass of the fluid control mechanism.
