There is provided a beverage pitcher in which is mounted a stirrer device for stirring or agitating the contents of the pitcher. The stirrer device includes a plurality of axially spaced vane lobes which are substantially equiangularly spaced about a longitudinal axis. The maximum radial extent of the vane lobes from the lognitudinal axis decreases in the direction from the lower end to the upper end of the plurality of vane lobes, so that during operative rotation of the vane lobes the stirring or agitating effect is at a minimum at the maximum upper level of the contents of the pitcher where only a minimum stirring or agitating effect is required and where substantial stirring or agitation is undesirable.

A stirrer device for a beverage pitcher, the stirrer device comprising elongated vane means which has a first end and an opposed second end and which comprises a plurality of axially spaced vane lobes substantially equiangularly spaced about a longitudinal axis, the maximum radial extent of the vane lobes from the longitudinal axis decreasing in the direction from said first end towards said second end of the vane means, and each vane lobe being of generally spiral form about the longitudinal axis with the edge thereof merging smoothly from the maximum radial extent of said vane lobe towards said longitudinal axis.
