Whenever family and friends have a party or go out for a picnic, they usually have beer kegs available. Thirsty people need to drink a lot so the keg is really cost effective and could save money. The device that allows you to release the beer into your drinking cup from the keg is a keg tap. If you do not know how to use a keg tap, then you can waste a lot of beer, and this is why you need to be careful is using it since it is actually easy to use. Foam can be released from the keg tap if not done properly, and it can go all over your face or your body. You would see people doing this but it is not as easy as it looks.
The release of the beer is regulated by the keg tap. With the use of a lever and with the actions of pulling and pressing it, the beer is released. It works by releasing the pressure, which in turn pushes the beer up and into a glass or a container. Keg taps work like switches which you can put on or off or it can also be an open-close switch.
You can minimize the foam created when pouring by placing the beer keg in a steady position for a short while. Foam build up is the result of too much movement when the keg is being transported. Let it stay for a while and place the keg where you plan to serve the beer to minimize the foam. Remove the cap or seal since it will be harder to tap with it. However, the pros do not remove the cap or seal because they will not put the beer at risk like you will. Since we are not pros we should play it safe.
A portable keg system can be tapped with CO2. The keg receives pressure in a single unit pump and tap combination and this is called party pump. IN this type, the keg and the beer keg tap are separated. You attach the pump, and the faucet must be opened so that the pressure in the keg is released. Air pressure is applied to the keg by pumping and when the lever is pushed, which is the tap handle, beer is released.
A portable beer keg or a pony keg should be finished in a single because after that the beer loses its flavor when it is mixed with air. In a traditional keg and on and off valve is used. By using this, you are serving by gravity, and there is no air pressure needed. When the valve is used, you simply turn to open or close the keg to get some beer.
