Abstract: A punch down apparatus for punching a wine cap of a wine residing inside a fermentation bin is disclosed. The punch down apparatus includes a frame assembly having a frame coupled to a plurality of legs supporting the frame on a ground surface, a track assembly supported on the frame and adapted to slide relative to the frame in a first direction. In addition, the punch down apparatus includes a carriage assembly mounted on the track assembly and adapted to slide relative to the track assembly in a second direction substantially perpendicular to the first direction, and an actuator assembly attached to the carriage assembly and adapted to move along with the carriage assembly. The carriage assembly includes a punch plate arranged downwardly of the frame and adapted to contact and punch the wine cap, and a linear actuator adapted to reciprocally move the punch plate in a vertical direction.
