When Foamy Beer Strikes: How to Fix It

Lately, it seems that we've had a ton of people stopping by our office because their wild draft systems insists on pouring overly foamy beer and they don't know how to fix it. Lucky for them, we know a thing or two about correcting that problem. The first step you need to take is to identify the problem. There are a few reasons your kegerator might be pouring with a ton of foam:
  • Your beer may be warm
  • You could be using too much CO2
  • Your beer lines might be too old
  • You could be a terrible beer pourer
  • The faucet may be dirty or obstructed
  • The parts inside of your faucet may need to be replaced
  • Your beer line could have warm spots
Now, let me elaborate on these issues and fill you in on how to correct them.
  • Warm beer: Your keg should always be kept between 38°F and 40°F – that doesn't mean that you put it into your cooler or refrigeration unit and it's automatically the perfect temperature right then and there. Give it time to chill – literally.
  • Too much CO2: Adjust your regulator to lower the amount of CO2. In a normal fridge setup you want your regulator set between 10 and 12 PSI. If the keg is over pressurized, simply pull the relief valve on your coupler for about 3 seconds, then wait 15 minutes and turn your CO2 tank back on.
  • Old beer lines: They get gunky and they can be gross. The stuff that forms inside of them can cause foam. Replace beer lines if they're old (meaning they're any color but clear, or visibly show deposits).
  • You suck at pouring: A bad pour can mean a lot of foam. If you pour correctly and your system is running well, the head on your beer should be between ½" and 1" high. Make sure you open the faucet quickly and completely. Read this pouring guide to learn how to pour properly.
  • The faucet needs cleaning or fixing: Every few weeks you should remove and disassemble your faucet, then clean it with hot water and a brush. The washers inside wear easily; so make sure to replace them when they need it.
  • Warm spots: If all of your tubing isn't kept inside of your fridge, you're in big trouble. The lines need to stay consistently cold so the beer doesn't rebel and get foamy before you pour it.
