A filling plant for handling bottles as required, has at least one bottle handling device, a first supply line which supplies a first bottle type and at least one further supply line which provides a first further bottle type, the first further bottle type differing in shape and/or size from the first bottle type. In order to increase the flexibility, to reduce the inventory and nevertheless to meet the requirements for mass production, the filling plant also has a sorter which is configured to remove bottles selectively and arbitrarily from each of the supply lines, to line up the bottles in a predetermined order on a forward section and to deliver them to the bottle handling device in the predetermined order. The predetermined order can be chosen freely.
