Action description

The audience will learn details about the meaning of energy and power, different heat exchanger design as well as about the role of pressure in lautering.

In this talk, Dr. Alexander Neubauer takes you on a journey through the exciting world of physics and thermodynamics within the context of homebrewing. Though, of course the laws are true for brewing in a large scale as well, the examples and tools are chosen from the homebrewing context. Starting from basic terms like energy, power and efficiency, the journey leads along the brewing process to the pressure distribution when lautering and how the avoid the big “lautering catastrophe”. After lautering the boiling is investigated in greater detail, especially the question why the water only evaporated slowly from the wort. After the wort has reached its maximum temperature within the brewing process, we address the question how to chill it quick and efficient to fermentation temperature. Thereby we illuminate different heat exchanger designs as well as the question why ice cools better than you would expect at a first glimpse.
