Large key (dialect: Köllaschließl) made of metal, with which the door to the wine cellar or press house was locked. Besides its purely practical purpose, the cellar key had a high symbolic value and was, so to speak, the "sceptre" of the winegrower. The key was always kept by the master of the house, sometimes he even went to bed with it so that young people could not get hold of his wine. An important sign of trust was to leave the key to a friend. If you were given the cellar key by a winegrower, you had won his trust and friendship. Handing the cellar key to the son also had an important meaning and was, so to speak, the handing over of the sceptre. See also a complete list of thematic keywords under wine-growing customs.
