and developed the bottom-fermented beer — Schwechater Lagerbier — which he presented in 1840/1841. It was a new style of beer, methodically bottom fermented to produce a brew that was coppery reddish-brown in color. It required steady, cool temperature for maturation and storage, and this requirement gives the beer its name: lager (in German, Lager means storehouse or warehouse). Originally, he called the beer Märzen, or March beer. Although situated in Austria, Anton Dreher strictly kept to Bavarian brewing methods in his brewery and therefore only brewed beer in the winter months between October and April when natural temperatures allowed cool fermentation and the collection of ice for the lagering cellar. In this tradition, Märzen was the last beer brewed in a brewing season, sometimes to a greater strength. In 1858, Dreher's Lager won the gold medal for excellence at the Beer Exhibit in Vienna. On 26 November 1861, Emperor Franz Joseph I honoured Anton Dreher's work by visiting his brewery. At the International Exhibition in London 1862, Dreher presented four types of beer for which he received a bronze medal. In recognition of this success, Anton Dreher was made a Knight of the Imperial Austrian Order of Franz Joseph by the Emperor. The Danube river provided the water needed for unlimited beer and malt making. The attention turned to Kőbánya because of a beer made by Peter Schmidt, a brewer master from Pest who studied in Munich. Schmidt stored beer in his rock cellar in Kőbánya. The water in the wells, made by deep drilling technology, is perfectly suited for beer making; the cellars of Schmidt's brewery provided the steady cool temperature needed for maturation and storage. It was the ideal warehouse, or, in German Lager, for storing the beer. The surge of the Kőbánya beer production attracted Dreher's attention, in part because Schmidt's beer was competition for him. He visited Pest-Buda on several occasions between 1856 and 1860; by 1862 he was able to buy the Kőbánya Brewery Company. He purchased further plots of land and prepared for expansion, but died suddenly in 1863, leaving his 14-year-old son to implement the plans. The brewery under the son's leadership After his father's death in 1863, Anton Dreher continued the work on the brewing process. He started to export this beer first to the Netherlands, then to Triest (now Trieste), where it was known as Birra Dreher, and then to
