material being disposed on the periphery of said rotor;
each of said plurality of beverage bottle or container filling elements comprising a container carrier being configured and
disposed to receive and hold beverage bottles or containers to be filled;
each of said plurality of beverage bottle or container filling elements being configured and disposed to dispense liquid beverage
material into beverage bottles or containers to be filled;
at least one liquid reservoir being configured to hold a supply of liquid beverage material;
at least one supply line being configured and disposed to connect said at least one liquid reservoir to said beverage bottle
or container filling machine to supply liquid beverage material to said beverage bottle or container filling machine;
a first star wheel structure being configured and disposed to move beverage bottles or containers into said beverage bottle
or container filling machine; and
a second star wheel structure being configured and disposed to move beverage bottles or containers out of said beverage bottle
or container filling machine;
a third conveyor arrangement being configured and disposed to convey filled beverage bottles or containers from said beverage
bottle or container sterilizing machine to said beverage bottle or container filling machine;
a rotary beverage bottle or container closing machine being configured and disposed to close tops of filled beverage bottles
or containers;
said beverage bottle or container closing machine comprising:
a rotor;
a rotatable vertical machine column;
said rotor being connected to said vertical machine column to permit rotation of said rotor about said vertical machine column;
a plurality of closing devices being disposed on the periphery of said rotor;
each of said plurality of closing devices being configured and disposed to place closures on filled beverage bottles or containers;
each of said plurality of closing devices comprising a container carrier being configured and disposed to receive and hold
filled beverage bottles or containers;
a first star wheel structure being configured and disposed to move filled beverage bottles or containers into said beverage
bottle or container closing machine; and
a second star wheel structure being configured and disposed to move filled, closed beverage bottles or containers out of said
beverage bottle or container closing machine;
a fourth conveyor arrangement being configured and disposed to convey filled beverage bottles or containers from said beverage
bottle or container filling machine to said beverage bottle or container closing machine;
a rotary beverage bottle or container labeling machine being configured and disposed to label filled, closed beverage bottles
or containers;
said beverage bottle or container labeling machine comprising:
a rotor;

a plurality of beverage bottle or container support structures being disposed on the periphery of said rotor;
said beverage bottle or container support structures being configured to support and hold filled, closed beverage bottles
or containers;
a first star wheel structure being configured and disposed to move filled, closed beverage bottles or containers into said
beverage bottle or container labeling machine;
a second star wheel structure being configured and disposed to move labeled beverage bottles or containers out of said beverage
bottle or container labeling machine; and
at least one beverage bottle or container labeling device being configured and disposed to affix a label to the surface of
a beverage bottle or container;
a fifth conveyor arrangement being configured and disposed to convey filled, closed beverage bottles or containers from said
