Between 1918 and 1939, the brewery merged with neighbouring competing companies, but came under provisional administration of the Polish state intermittently from 1934 due to unpaid taxes.

After the expansion of the brewery in the nineteenth century and the introduction of bottom-fermenting, they started to produce Tyskie lager, a relatively short Bavarian beer.

The label depicts a royal crown to commemorate John III Sobieski king of Poland, who was born in 1629, the same year the family von Promnitz established a brewery in the town of Tychy.

The Tyskie Brewing Museum represents an important "anchor point" of the European Route of Industrial Heritage in Poland.

In 2005 in Munich at a global beer fair hosted by Drink Tec, Tyskie again received the Grand Prix.
