According to Google Translate and the mill's website, this is the story of the mill and the restaurant:
"The best thing to remember is the current name: "Kaffeemuhle" - because we want to tell her story.
"Wherever flour had to be ground, Muller settled in the last centuries. They were either looking for a rushing stream or river (like the Weser) or a small hill where the wind could blow them a little more than in the shallow, northern German lowlands: on the heights before the gates of Bremen, on the city gates and The bastions of the fortifications gradually formed about a dozen windmills.
The "Kaffeemuhle" was built in 1699 by Moritz Meier - his first mill had to yield to a fortification (the Doventorswall). But even his new building was not long-lasting: the complaint of unfair competition (yes, yes, So what was already there at that time ...) led to the fact that he had to build again soon: on the Junkers bastion in the fortifications (where the Olbers planetarium was built in 1850).
"But even this predecessor of today's building did not last long. The wind conditions there were so bad that he chose a more airy place and moved to where you are drinking your coffee today, enjoying your cocktail or eating relaxed in a pleasant atmosphere.
For over 100 years it was quiet around the mill - which suggests that there were honest owners who did not like their customers too much, and were not too annoying to the competition. In 1832, however, the "coffee mill" burnt down; A year later the place was sold to the mills of Erling, Who at once erected a new mill. Erling built modern: he had the tall substructure erected so that the wind could better hold its wings than in the old building.
"Little is known about the decades that follow; It was quiet again around the "coffee mill". But technology continued to develop; Windmills were always more unprofitable, since steam-driven machines were able to grind flour more quickly and cheaply.
"That is why the owner was ready to sell his mill and the city of Bremen attacked (for less than a third of the estimate - the politicians could then really count ...).
"In 1891, the Bremen guarantee extended to the purchase - and had only a few years' pleasure in this decision.
"After the fire the responsible "deputation for the walks" was besieged by the inhabitant to rebuild the mill. "In the interest of the scenic character of our fortifications," the deputy agreed; Around 1900 the mill was restored in its old beauty. But ground was only rarely in the middle of the fortifications.
"After the Second World War (which the mill survived only with much luck and great efforts of the then tenant), the Senate finally allowed the tenant to entertain a school in the mill. It existed until 1997 - then the mill was renovated, a cultivation was erected (based on historical models) and the mill on the wall to the "coffee mill". Now here is also ground again: No flour, but coffee - the "coffee grinder mix"."
