This pressing stone comes from a Roman wine press that stood at the foot of the Rosenberg near the church in the 2nd and 3rd centuries, as evidenced by small late Roman artefacts and body burials.
In Roman wine presses, the grapes were processed in two stages: Firstly, the grapes were mashed with feet or stampers and then pressed in the actual wine press basin. Tree presses were used for this purpose, which utilised large pressing stones as a counterweight. By turning a wooden spindle to which the stone was attached, pressure was generated via the wine press tree in order to press out the mash.
The reddish sandstone Kelterstein was found in 1975 during the renovation of a barn in Kinheim Pützgasse. Today, only half of the stone, which weighs around 36 hundredweights and was placed here in 2010, remains.
