Gases in a Brewery

Gases of all sort are needed to produce beer. Can you name them and Explain how they behave?


Steam, Nitrogen, Expansion, Gas, Oxygen, Carbon dioxide, Gas Laws, Matter, Air


This lecture discusses the more common characteristics of gases and the way they interact with processes within a brewery, as well as the environment in which the people work. The content expert sets a background for the presentation on gases by addressing first the states of matter. Secondly, he explores thermal expansion, the effects of gas densities, and the various gas laws. Finally, the importance of safety, particularly in terms of carbon dioxide, is stressed and reviewed.

Learning Objectives

  • Explain the main use of compressed air in breweries
  • Describe thermal expansion
  • Identify the 2 variables accounted for in Boyle's Law
  • Explain the Kinetic Theory of Gases
  • Provide valid information about the main gases used the brewery
