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.
it's normal to have sediment at the bottom of the bottle, it's just the yeast
that caused the carbonation of the beer. If it's a very thick layer, it's a
sign that you should have waited longer for the beer to clear before you
just pour yourself beer into a clean glass and Enjoy!
I know of one trick that might solve your problem . First , make sure the lever that swings up and down during cycle is all the way down . Then , pour one eight ounce cup of water into the ice maker where the slots are . Hopefully , when the water freezes , the ice maker's sensor will detect the ice and start the dump cycle . If it does , and everything is OK inside the unit itself , it should be OK after it ejects the ice .
Shut of the CO2 tank, then hit the pressure release valve on the side of the beer tap. Make sure there is a grey check valve in the tap where the red hose (co2) is connected. Also make sure the white ball in the tap where the white hose (beer line) is not stuck. You can remove this, it isnt really necessary. Once all checks out, open the tank and readjust the co2 regulator. The reading should not be more than 12 PSI. Everything should work just fine after this. Make sure the glass is as close to the faucet as possible (slanted is better) when dispensing beer. Hope this help :)
Draught (or Draft) beer is almost always un-pasteurized and therefore is more fragile. It should be consumed after being "tapped", and is generally truer to the flavors of the ingredients as pasteurization exposes the beer to heat and changes the flavor profile. Always use brewery approved beer line if you want to have foam free fresh tasting beer. Serving it through a plastic tube from the hardware or discount store or the plain vinyl tubing in your beer tap system you will wind up with a foamy, off tasting beer. Real draught beer is not pasteurized. It must be kept refrigerated between 35F. and 44F. A beer will become wild, turn sour and cloudy in a day or two. Below 44F. a keg of draught beer should last 20-30 days before it loses it's fresh brewery taste and aroma. Craft beers (micro brews) tend to have a shorter shelf life and you should contact the brewery for their recommendations.
Why does my beer foam up?
The 3 most often causes of beer foaming up are:
The temperature of the beer keg
The balance of the draught beer system pressures
The cleanliness of the draught beer system
I would suggest that you clean or replace the beer transport tube...
If you are getting foam then finally poors fine you have a temperature problem. If you are getting constant foam then you are probably looking at a pressure problem. First of all make sure that you let your keg sit for at least 4 hours and get down to 38 degrees before you tap the keg. Also ensure that your pressure is set to at least what the pressure is in the keg (generally 13 psi). If you can, try to ask the beer manufactures (if you use a microbrewery) what pressure to set it at. One brew master told me to start at 15 psi and adjust from there.
If you still get foam and you can guarantee that the temperature is correct then you are getting some agitation from something else. Double check all your washers and even check your stop valve on the CO2 line to the coupler. Sometimes the lines are not the correct length or even the correct diameter, when the beer is forced through the line if it starts out thin and then expands or vice versa that gives beer a chance to get agitated and cause foam.
Finally the equipment that is used on these systems are generally not that great. I had a Danby Chill'n Tap and replaced the coupler and the tap and all the lines and that solved my issues, even though my problem was probably a cracked valve for the < $80 it cost me to replace everything it wasn't worth my time to figure out exactly what was wrong with it.
Could be the thermostat isn't working and the unit is just running and running all the time. To me that seems the most simple explanation right now. Can you check the temp inside when on the lowest setting for a day, then turn it up to the highest for a day and see if there is a huge difference in temps? Does the compressor motor ever turn off or does it run continuously? Suspect that t-stat...
