How do I make my tap beer less foamy?

Tips for Reducing Kegerator Foam

1. Step 1: Temperature should be mid-low 40’s F (liquid temp, not air temp).
2. Step 2: Clean the beer line or replace.
3. Step 3: Beer line should be 3/16″ diameter.
4. Step 4: Use beer line that is 8 feet long.
5. Step 5: Set regulator in the 5-10 PSI range.

Why does beer line length matter?

A rich malty and hoppy beer needs as little as 7 PSI of pressure behind it, while for a light lager style beer, you will usually want something like 10-12 PSI to push it properly. The length of the beer line can also affect the amount of push needed for optimal pouring.

What happens if your beer line is too long?

Lines that are too long or too thin, or both, will slow the flow of beer down too much, and knock too much co2 out of solution before it reaches the tap. So, as you pour, your beer will be less carbonated than it is in the keg.

What causes foamy beer from keg?

The most common causes are: Incorrect Temperature – If the beer is too warm or too cold, it will be more easily disturbed and pour as foam. Make sure the glass is near the bottom of the keg (but not touching it) since that is where the beer is coming from.

How long should keg sit before tapping?

1 to 2 hours
Do not agitate the keg. If there has been excessive agitation during transportation, allow the keg to settle for 1 to 2 hours before tapping. Make sure the beer faucet is in the off position prior to tapping.

How long should my keg lines be?

Resistance can be created several ways but the easiest is just to increase the length of the beer line. 5mm ID beer line the length should be about 3-4.5 meters. 6mm internal diameter the length should be 5-10 meters. FAQ: Can you turn down the pressure on your regulator and use a shorter beer line to reduce foaming.

Is a longer beer line better?

In my previous article we covered how the temperature of the beer and carbonation level desired in volumes of CO2 drives the overall carbonation pressure – a number you can also calculate easily using BeerSmith. In general the longer your keg lines are, the lower the serving pressure at the tap.

How long does a keg need to settle?

A: You tap a keg by using a keg coupler. Do not agitate the keg. If there has been excessive agitation during transportation, allow the keg to settle for 1 to 2 hours before tapping. Make sure the beer faucet is in the off position prior to tapping.

Does pumping a keg make it more foamy?

A pour from a keg that’s too fast or slow will create foam. You can regulate the speed by how much you pump. It should take 10 to 15 seconds to pour a pint with an inch of foam. For the first few pints (when the keg is still under pressure), you may want to slow down the flow of the beer.

Are keg taps universal?

Not all brands of draft beer use the same type of valve in the keg. Each distinct “system” requires matching the appropriate keg coupler to the keg valve. In the U.S., there are eight different “systems” in use: “D” System (American Sankey): Most North American beers.

How much beer is lost to foam in a keg of beer?

This leads me to assume that 1/12 (8.3\%) to 1/6 (16\%) of beer is lost to foam. It is known that over carbonation, due to pure CO2 or incorrect mixed gas ratios pushing the beer to the tap, causes overfoaming. This overfoaming can cause from 5\% to 10\% of beer loss per keg.

Does the length of a beer line affect the foam?

For some this is not an issue, but if you use a draft tower you need to take care to refrigerate those lines and insulate the tower to keep CO2 release to a minimum, thus reducing foam in the glass. Beer line length MUST be balanced with the amount of pressure in the keg used for serving. The longer the line, the more resistance you have.

Why does the pressure drop on a keg of beer vary?

The pressure drop depends on resistance in the beer line. Beer lines have two types of resistance – one due to elevation change (i.e. the keg being higher or lower than the tap), and a second due to the beer lines themselves which generate friction as the beer flows through the lines.

What is beer line rise to tap?

Beer Line Rise to Tap: The height of the tap from the center of the keg. This provides resistance, keeping CO2 in solution by slowing the pour. There are some simple rules to follow as well as an equation to help you balance your beer line length to accommodate the pressure needed in the keg to sustain your desired CO2 volume.
