1. An apparatus comprising:
a first separator stage to separate an input fermented malt beverage (FMB) into a first separated FMB and a first portion of a non-alcohol cereal beverage (NACB), the first separator stage comprising:
a first packed column including:
at least one input port to receive the input FMB and to receive water;
a first output port to provide the first NACB portion; and
a second output port to provide the first separated FMB;
a second separator stage to separate the first separated FMB into an output FMB and a second portion of the NACB, the second separator stage comprising:
a second packed column including:
at least one input port to receive the first separated FMB and to receive water;
a first output port to provide the second NACB portion; and
a second output port to provide the output FMB;
at least one vacuum pump coupled to the first and second packed columns; and
a control unit configured to:
provide water to the first and second separator stages to maintain the separated FMB and the output FMB at the same alcohol by volume (ABV) as the input FMB; and
control input of carbon dioxide and vacuum pressure to produce a flow rate that maintains the output FMB at the same ABV as the input FMB.
