This was a brewery for 200 years from around 1600. Well-known beers from that time: Kluunbier, Maertebier and Jopebier (from Haarlem). Kluunbier is the oldest beer still brewed in the Netherlands, from the city of Groningen. This beer was very popular in Friesland. A possible explanation of the word klunen is the "wandering" after a bit too much Kluunbier. In later years, the word klunen became a skating term.
Cornelis and Sytse Hansma continued the business and brought the brewery to great prosperity; they wanted to let Dokkum know that too and in 1743 the Hansmas had their house renovated and embellished, so that everyone could see what a golden trade Dokkum beer was. In addition, a lavishly decorated facade stone was placed in the facade, with baroque curls and a gilded right hand, the symbol of the Han(d)sma family. From that time on, the brewery bore the name ‘De Gouden Hand’.
In addition to these buildings, there was also a beer house, where one could drink a glass of freshly brewed beer, which had the beautiful name ‘De Bierton’. Perhaps this house was also used as a cooperage, where beer barrels were made; the Hansmas had the entire beer production process in their own hands, from malting to storing and the taproom. The building of the taproom ‘De Bierton’ is now known as ‘De Zwarte Hand’ because of a facade stone from 1754, partly because according to folklore, this is where the heavy and dirty work was done, from which the Hansmas ran their golden beer trade. But was that black hand always so black? Or was the facade stone once also gilded and was it damaged by the fire or by time and were the hand and edge then painted black? From the website In-Dokkum.nl
