The "BrauAG" (brewing working group) of the Hochschule Hannover consists of students from different disciplines. Besides their passion for enjoying beer, they are curious about the optimal transformation of natural raw materials to a finished product. In our brewing cellar, they can develop new ideas for beer creations and implement them in initial tests on a 10L scale. Once a recipe has matured, it finds its way to the 100L large-scale system. The annual highlight is our participation in the international brewing competition of universities at the Technical University of Hamburg, which we even won in 2018! In teaching, beer brewing is part of the laboratory course during the compulsory elective module in bioprocess engineering.
