How to Hook Up a Keg

Beer keg tapping systems work by maintaining constant, controlled pressure inside the keg via carbon dioxide or nitrogen. The same pressure also dispenses the beer when a valve on the tap opens -- similar to a garden hose in principle. Hooking up a beer keg is a straight forward procedure that involves connecting the beer line to the beer-line intake valve located on top of the keg. Only hook up chilled beer kegs (below 38 degrees Fahrenheit) -- beer begins releasing carbon dioxide at temperatures above 38 degrees Fahrenheit, and bacterial growth begins at 50 degrees Fahrenheit.
