The Köstritzer brewery is one of the oldest producers of Schwarzbier (black beer) in Germany. It is in Bad Köstritz, close to Gera in Thuringia. History The brewery was first mentioned in inheritance tax documents as "Köstritzer Inheritance" in 1543, which makes it one of the oldest breweries in Germany. In 1696, the Counts of House Reuss acquired the brewery and renamed it to the "Knightly Estate Brewery." Since 1806, the brewery has been permitted to use the title "Princely Brewery" since the Knights of House Reuss were promoted to princes. In 1811, 6400 hectoliters (hl)(169,070.1 gallons) of different beers were produced and sold in cities as far away as Berlin, Dresden, Magdeburg and Frankfurt am Main. Johann Wolfgang von Goethe, who lived in Weimar, is recorded as having mainly bought beers of various types, from the Köstritz and Oberweimar breweries as well as bread rolls.

But he usually goes into another room when I'm there. The shyness does not go completely out in a human breast." In 1829 the company along with 15 other buildings in Köstritz burned down. As a result, the brewery was rebuilt in the west wing of the palace. In 1872 the agricultural inspector and later entrepreneur Rudolf Zersch leased the Russian domains of Köstritz, Dürrenberg and Hartmannsdorf and in 1875 the Princely Brewery Köstritz. The latter was initially expanded in the castle and at other production sites in Köstritz under the direction of master brewer Carl Holomoucky. Under Holomoucky, the varieties Köstritzer Schwarzbier and the lager Blume des Elsterthales were initially produced. From the 19th century to the first half of the 20th century, black beer was said to have a health enhancing effect. In an advertisement from 1893, the brewery advertised that it was "recommended by high medical authorities for the anemic,
