"Bembel"; Pitcher for cider

Today we were out and saw this pitcher.
The tile says:

According to legend, around 1000 AD, here at this point was the resting place of the monks on their way from Gemünden to Höhn.
With a refreshing drink, their "pot fell over".
Hence the name Pottum could come from.

Google translate doesn't quite understand it, I hope you do :-)
