the difference between foam and beer is known as 'change of state', also applies to refrigeration equipment, and is caused when pressures drop too radically. While temperature is a factor, you need to consider your pressurization method and settings more. What are you using to re-pressurize your keg as you dispense brew? CO2? Nitrogen? mix? assuming you dispense from the bottom of the keg (feed tube reaching down near the bottom) lowering the pressure should help reduce the amount of foam when pouring. The thing is, even if you pour a glass full of foam, it will settle over time into beer, and you can add to it until eventually you have a smiling glass of amber joy sparkling at you. Go check some of the articles at ambersuds.com.
Most of the time this reason is the beer temp and co2 is not right. first you dont go buy box temp but need to get beer temp. first make sure you have a calibrated thermometer. check your thermometer by mixing up a glass of ice and water let it stand a couple Min to achieve 32deg. put thermometer in water let stand 2 min to make sure it reads 32 deg. now draw a couple of glasses of beer in the same cup pour each in a pitcher. now draw a 3rd glass of beer in the same glass put the thermometer in it you wont the beer at 38 deg if to cold turn your box thermostat up or if to hot turn your box thermostat down to achieve a 38 deg beer. now it is time to check the CO2 pressure, you wont it at 12 psi. first drink a couple glasses with your friends this will let your keg pressure equalize. Now it is time to do a test poor. If the faucet gives a spurt of foam when you open it or the beer runs foamy-clear-foamy-clear than the pressure is too low, bump the pressure up 2 LB and let the pressure equalize a few min. If the beer runs to fast, turn off the co2 at the shut off where the tubing connects to the regulator (Always turn off the shut off when adjusting the regulator). Release some pressure from the keg by pulling the pressure relief valve on the keg coupler. Drop the co2 pressure 2 lbs. Turn the co2 line back on and let the pressure equalize. Often you can tell if the pressure is too low by looking at the beer line at where it connects at the keg coupler. If you see bubbles rising up the beer line from the coupler the pressure is to low or the seal on the keg or coupler is bad. Over many years of trouble shooting 3/16" bore shanks and fittings can cause a burst effect releasing carbonation from the liquid. The beer flow looks good but you end up with a glass half full of beer and half foam. For this reason 1/4" bore shanks and fittings should always used on the liquid side.
" It is the ultimate beer-tasting utility glass. The bulbous bottom makes for great drinking, the flared mouth allows for wonderful head formation and aroma release, and while it is short enough to handle the biggest beer styles, it is tall enough to service IPAs and other complex session beers. The Duvel glass is a well-known variant of the tulip style, and the Ratebeer tasting glass is an almost perfect example." -http://www.ratebeer.com/ShowGlassware.asp?GWID=9
In its most simple
form, craft beer is any beer not brewed by one of the big brewery
corporations. The term craft beer is
most commonly used to describe a beer made by an independent brewer in small
quantities.
Essentially, no.Some people may argue this statement, but
basically what they taste is the aluminum.Try pouring the beer into a glass - it will taste the same.Cans are a great way to store beer; however
they are not often used due to the cost surrounding their manufacturing
process.
Bock beers are brewed in
Germany and are considerably darker and stronger styles of beer. If you would like to know more about
different style and types of bock beers I would recommend visiting the link

Take out the temp sensor in the white cage on the left, and put it in a glass of water. That will measure liquid temp instead of air temp. your beer is too warm
