Weird foam clusters

[lukez8513]

This is the first time I did a recipe from scratch, this is only my 4th homebrew. It's a brown ale extract with williamette and east kent goldings. It tastes fine but has a bitter aftertaste I'm not sure of, it's not overbearing just new to me. But I was curious as to why the foam clusters like this?

More CO2 is being released by the yeast cake under that portion of beer. Looks normal to me.

Edit: is that your glass you are drinking from? Same reason sorta. More CO2 being released from that portion of beer in your glass. Some times you can see this if a glass hasn't been washed properly. You will see CO2 appear to be being released from the side of your glass, inside of course.

Surface tension? Looks normal to me. Let it age a while and the aftertaste should improve. Time heals (almost) all wounds.

Age was kinda what I was wondering. Thanks. Plus I never considered the glass
