Grape-treading or grape-stomping (also known as pigeage) is part of the method of maceration used in traditional wine-making. Rather than being crushed in a wine press or by another mechanized method, grapes are repeatedly trampled in vats by barefoot participants to release their juices and begin fermentation. Grape-treading was widespread in the history of winemaking, but with the introduction of industrial methods, it now survives mostly as a recreational or competitive activity at cultural festivals.
One of the earliest extant visual representations of the practice appears on a Roman Empire sarcophagus from the 3rd century AD, which depicts an idealized pastoral scene with a group of Erotes harvesting and stomping grapes at Vindemia, a rural festival.
Many contemporary wineries hold grape-stomping contests to attract visitors. The practice is also the subject of many depictions in contemporary media, including the 1974 Mel Tillis song "Stomp Them Grapes", the I Love Lucy episode "Lucy's Italian Movie", and The Littlest Grape Stomper, a children's book by Alan Madison.
