Named after the district of Księży Młyn (ENG: Priest's Mill), which is also the old name for the Herbst Palace Museum, this brewery first appeared in 2014. Operating in conjunction with their restaurant, Gronowalski, the site has garnered a crowd of regulars who take their food and alcohol seriously as well as unusual atmosphere created by the interior located in the historical part of Łódź. The brewery uses groundwater sourced from the Łódź city area, which is 90% of the water-based ingredients used in their beers. Beers available on tap include Przędzalniane, Lniane, Satynowe, Jedwabne or Bawełniane (ENG: Cotton) that acknowledge the industrial past of the area.
