Home brewing spunding valve in action!

Definition:
To Spund is German for bung, meaning to close up or seal. Spunding in brewing refers to the act of closing off a vessel containing beer or wort and allowing pressure to build inside the liquid. This is useful in the natural carbonation of a beverage such as beer. The spunding valve is a device consisting basically of a pressure gauge to show vessel pressure, and some way to release unwanted excess pressure from that vessel. Normally something such as an adjustable back-pressure relief valve is used to control a set pressure, venting any excess gas out of the vessel.
In this picture a simple on/off valve is used when venting, so there can be many variations on the broad idea.
Use in brewing:
Spunding valves help the brewer by allowing natural carbonation to build up. This happens inside a fermenting beverage when the vessel is sealed up toward the end of primary fermentation, or after the beverage is transferred to another vessel containing more fermentable sugar for carbonation during a secondary fermentation. Transferring or racking into another vessel containing fermentables after primary fermentation is complete is known as priming. This, is a really good article on spunding I found on the web while doing my research. Here, is a really good article where Kaiser talks about transferring or racking beer from one keg to another under pressure or "counter-pressure".
Also used in conjunction with the Closed-System Pressurized Fermentation technique.
