An apparatus includes a body having a length extending from a first end to a second end. The body defines a bore extending through the entirety of the body and at least one of a plurality of grooves or holes around the bore. The body has a length that is dimensioned to be received entirely within a neck of a container.

A container system for liquids, including an in-container mixer/aerator in the exit throat of the container. The mixer/aerator is a cylinder, having axial peripheral grooves, and and axial central bore, divided by axial vanes.

An aerator and an associated method and system are provided. The aerator includes an elongate body having a central bore that extends between proximal and distal ends of the body, and a plurality of channels formed in an outer surface of the body, the plurality of channels extending between the proximal and distal ends, and including at least two bends along their lengths. The bends in the channels help to provide a smoother flow of liquids passing through the aerator.
