Why is my beer still foamy?
In order of likelihood, here are the answers:

Your beer is too warm. It has not had enough time to cool to 38º F. Give it 24 hours in the cooler to cool. In the meantime, check the temperature, then call your retailer or wholesaler and let them know that they are not selling their customers properly chilled beer.
Your beer is too warm. Your cooler is not running at 38 º F. Turn the temperature control down.
Your shank is too small. You need a 1/4” shank. Pouring beer quickly through a shank will cause a rapid pressure drop and will create foam.
Follow the pouring instructions. You need to be sure to fill the glass from the bottom up.

Why is my beer to warm?
It likely came from the store that way. A ½ barrel needs about 2 hours to cool for every degree over 38º F.

The first beer is all foam and then the next beer is fine. Why is that?
The beer sitting in the line between the keg and the TurboTap is warming between pours. If you have a draft tower, make sure that there is an ample supply of cold air flowing up into the tower. If you take the lid off of your tower, there should be enough air coming out to extinguish a lit match.

Every time I get a new keg it’s really foamy, it doesn’t start pouring well until I’m down to the “bottom half.”
A1: Your pressure is too low. The foam is building up in the keg and in the tubing before you even start to pour. By the time you get to the “bottom half” of the keg, the beer has gone flat from lack of CO2 pressure. Flat beer will never be too foamy.

A2: Your keg was warm when you bought it. People are stunned at how long it takes a refrigerator or cooler to cool a keg, even a few degrees. A keg left out of a cooler for only two hours takes twenty hours to cool back down. By the time you get to the “bottom half,” the beer has had time to cool down to 38º F. This is the nature of heat transfer, the details of which we will spare you.

I have been through the whole troubleshooting flow chart and I still have foamy beer. What’s going on?
With the correct temperature and pressure and all new equipment, we have success 95% of the time. Occasionally, a faulty coupler is the mysterious problem. I have run into foamy beer, examined the coupler and found it to look pretty good. For lack of a better idea, I switched the coupler and immediately poured better beer. For the perplexed home user it’s worth a shot.

How do I tell if my cooler is the right temperature?
Keep a bottle of water in the cooler and measure the temperature of the water. The air temperature in your cooler changes every time you open or close the door and whenever the compressor kicks on or off. The average temperature (often called the “liquid temperature”) is what really matters. It should be 38º F.

How do I know how much CO2 I have left?
Your pressure regulator should have two gauges. One displays the pressure in the tank and the other displays the pressure in the keg. Your CO2 tank should always have at least 100 psi in it. If it drops below 100 psi, it’s time to refill. There is nothing worse than running out of CO2 in the middle of a party.

I made a tap handle out of the gear shifter from a 1972 Dodge Ram 3500. Is this a good idea?
No. The bigger and heavier your tap handle is, the slower it will open and close. Slow means foam. The on/off action of the tap should be more like flipping a switch than shifting gears in a truck. Fast, light and quick is good. Big, heavy and slow is bad.
