A beverage supply system includes a beverage container having an outlet. A first reservoir is connected to the beverage container outlet to receive beverage from the beverage container under force of gravity. A pump is connected to the first reservoir, and a second reservoir is connected to the pump, the second reservoir defining an expandable beverage chamber. The pump is activated to pump beverage from the first reservoir to the second reservoir only when a first quantity of beverage in the first reservoir is within a first quantity range and a second quantity of beverage in the second reservoir is below a second quantity range. The system also includes a beverage dispenser connected to the second reservoir. A method of supplying beverage from a beverage container to a beverage dispenser includes supplying beverage from a beverage container to a first reservoir under force of gravity. The method also includes pumping the beverage from the first reservoir to an expandable pressurized chamber of a second reservoir when a first quantity of beverage in the first reservoir is within a first quantity range and a second quantity of beverage in the second reservoir is below a second quantity range. The method additionally includes intermittently connecting the pressurized chamber to an outlet of a beverage dispenser to supply beverage from the second reservoir to the beverage dispenser without pumping the beverage from the second reservoir to the beverage dispenser.
