There are a number of decency rules, how to settle in one wine cellar but also has to behave in tasting rooms. Often this is often made in a humorous way on signs in the entrance area in rhyme form. In ancient times, there were also penalties for non-compliance with the rules, which were mostly articulated in prohibition form. The sinner was from the winemaker or Keller servant about an empty one barrel and the extended back with the "basement knife" or "Bandmesser" (an old craft tool of the cooper ) with blows. The prohibitions are locally somewhat different, but without exception are the knocking on the barrels (to the level cussing, screaming, singing, smoking and Drink,
Most prohibitions are self-explanatory, however, there are several interpretations of the "knocking on barrels". One of the oldest reasons for the prohibition are the sound waves generated by the knocking, which adversely affect the wine ripening at rest. The second most frequently mentioned reason is the unseemly curiosity, because as a guest one does not open boxes, for example (empty barrels sound differently than full barrels). A beautiful example is on a blackboard in the basement of Bürgerspital to the Holy Spirit in Würzburg to find (right in the picture):
Listen, viellieber Kellergast, what you have to judge,
When you enter the realm of wine, "Pfülben", "Neuberg" or "Stein".
First: do not smoke like a vent! There is a strict smoking ban here,
because noble wine and cellar air, tolerate no tobacco fragrance.
Point two: the knocking stopped, full as the empty barrel.
You also do not move in the strange house, out of curiosity the drawers out.
Thirdly: Gröl and do not blaspheme! You put weight on good tone,
And besides - as you know, you are a guest of the "holy spirit" here.
If you do not stick to the cellar law, you will be instructed by the Kellerknecht,
not exactly polite and humane, just look at his fists!
