In 1867, Dreher's Kleinschwechater brewery presented its beers at the 1867 International Exposition in Paris. It built a restaurant in the park of the Expo's Austrian section which included two ice cellars to store the beer under optimal conditions. Using custom-built ice wagons that ensured a constant temperature of 4°C, the brewery could transport 54 hectolitres of beer from Klein-Schwechat to Paris, a journey that took 5 days. The brewery was awarded a gold medal for the beers presented.
