~ Je der Stamm und seine Aeste ~
It seems like the branches feed off of the tree and the drinkers sponge off of the innkeeper. The PUG (printed under glaze) stein is ca. 1900.
Je der Stamm und seine Aeste, So der wirt und seine Gäste.	As it is with a tree trunk and its branches, so it is with an innkeeper and his guests.
