Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for control of beverage dispensing. In one aspect, authorization data specifying that a beverage dispensing node is authorized to be activated are received. Activation data that request activation of the node are also received, where activation of the node causes a valve that controls flow of fluid to a beverage dispenser to be opened. A determination is made that the activation data are associated with a user identifier for an enabled user, where an enabled user is a user that has been enabled to activate the node. In response to receipt of the authorization data and the activation data a valve that controls flow of fluid to the beverage dispenser is opened. Data (e.g., de-authorization or de-activation data) specifying that an activated beverage dispensing apparatus be de-activated can also be received. In response to receipt of the data, the valve can be closed.
