There are a number of decency rules on how to look at yourself wine cellar, but also has to behave in tasting rooms. Often this is shown in a humorous way on signs in the entrance area in rhyming form. In ancient times there were also penalties for non-compliance with the rules, which were mostly articulated in a prohibition form. The sinner was born winemaker or Keller servant about an empty one barrel laid and the extended back with the "cellar knife" or "band knife" (an old hand tool of the cooper ) processed with blows. Although the prohibitions vary somewhat locally, knocking on the barrels (around the level ascertain), swearing, screaming, singing, smoking and Drink,
Most of the bans are self-explanatory, but there are several interpretations for "knocking on barrels". One of the oldest reasons for the ban are the sound waves generated by knocking, which negatively affect the wine that matures in peace. The second most common reason is the excessive curiosity, because you don't open boxes as a guest (empty barrels sound different than full barrels). A nice example is on a blackboard in the basement of Bürgerspital to the Holy Spirit in Würzburg to find (on the right in the picture):
Hear, dear cellar guest, what you have to do,
When you enter the realm of wine, "Pfülben", "Neuberg" or "Steins".
First, don't smoke like a chimney! Smoking is strictly prohibited here,
because fine wine and cellar air do not tolerate the smell of tobacco.
Point two: do not knock on the full or empty barrel.
You don't pull in the strange house either, out of curiosity, pull out the drawers.
Third: Gröl and do not bother! You put emphasis on good tone,
and also - as you know, you are a guest of the "holy spirit".
If you do not abide by the cellar law, you will be instructed by the waiter,
not exactly polite and humane, just look at his fists!
