This process has not been fully explained and is still debated by researchers today. The role played by Jan Ewangelista Goetz (1815–1893) has remained unrecognized until now. He is primarily known as the founder of the brewery in Okocim. After leaving his family village, he worked at the brewery in Klein-Schwechat owned by Anton Dreher (1810–1863), a relative of the Goetz family. He described this period of his life in his diaries, which became part of the family archive after his death. During the occupation, the brewery was placed under German administration. The documents ended up in the possession of German historian Joseph König and were taken to Munich at the war’s end. In 1982, Jan M. Włodek, a relative of the Goetz-Okocimski family, discovered them, brought them to Poland, and added them to the family archive. The contents of the diaries shed new light on the beginnings of the popularization of bottom fermentation. Although the technology appeared to be a novelty, it had been known to brewers as far back as the Middle Ages. The breakthrough came with implementing temperature control using natural ice, which Goetz proposed and introduced at the brewery in Klein-Schwechat. Out of the combination of scientific inventions, such as the saccharimeter or the thermometer, and new technical advancements, a new style emerged that perfectly catered to consumer tastes. Although modern lager was developed in several places, Klein-Schwechat seems to be the most significant.
