What does the term "gushing" refer to in the context of serving beer?

The term "gushing" refers specifically to the rapid overflow of beer from the bottle when it is opened. This phenomenon occurs when there is excessive carbonation in the beer or when the beer is agitated, causing the gas to rapidly escape and create a foam that can spill over uncontrollably. This is often an undesirable situation for both the server and the consumer, as it can lead to a waste of the beverage and a less enjoyable drinking experience.

Understanding gushing is important for those serving beer, as it can affect the presentation and the perception of the quality of the beer. Taking care when pouring and managing the conditions of the beer, such as ensuring it is not overly agitated before opening, can help prevent gushing.
