Scottish name for originally a cap hen (crown hen, comb hen, tufted hen). But it was also common for a large, bulbous tin pot with a chunky hinged lid, the shape of which is reminiscent of such a hen. These jugs usually contained 2.25 litres and were used as measuring and transport cups for wine, especially port wine. Some brands of port wine are also filled in this bottle volume (see picture). The volume corresponds to three normal bottles with 0.75 l or also to the bottle sizes Marie-Jeanne and Tregnum. See also under bottles and wine containers.
