Increased foam with decreased volume?

Hi All,
After my approx 4th Keg (ever kegged) I’ve noticed increased foam/head as the keg nears being emptied. Is this a normal occurrence?
Thanks, Mike

Not something I have observed. Done about 12 kegs now and haven’t noticed this phenomenon.

What is your serving psi?
Perhaps the serving psi is too high and over carbonating the last bits over time?

I’ve observed this too. I’ve theorized that it might be because the bottom part of the fridge is the coldest and so the beer does not equalize with the warmer beer at the top of the fridge. Either that, or because the fridge lacks thermal mass with an empty keg, it gets colder on the on/off cycle and over-carbonates because of this.

I had this issue with some styles more than others. Once the keg volume is down around that bottom third or so and I noticed the foam increase, just dial the gas down to all but off and good to go. With a Keezer and a balanced system this issue will petty much disappear.

There is plenty of gas to finish dispensing the remainder.

If Mullerbrau decrees it then it must be true. Thanks Gents!
