I brewed an oktoberfest. Everything went fine during the brew session. I'm drinking it now and noticed the head pours great then falls into this weird coagulated-cottage cheese look that I've never seen in my 6 years of brewing.

What it be? Has anyone else seen this?

peace out!

Yes, my Oktoberfest happens to look just like that - it is the Marzen Madness recipe from BCS made with 34/70. I don't notice any flavor or mouthfeel impact. Not sure what causes it exactly, but I've seen other commercial beers that do this too.

I'm having the same problem with a recent batch. The head forms tight knit groups of tiny white foamy bubbles. The bubbles cling together in small groups and the groups almost repel each other, it looks weird if you watch closely, unlike any home brew I've made before.

The beer was 10# of pilsner malt with a Kolsch yeast and Saaz hops. Not sure if the ingredients matter but I can't think of anything in my process that was different from 2 recent batches which do not have this problem.

Most of my beers end up looking like that. No need to worry.

Do you know what causes it, coalcracker? Most of my kegged beers exhibit this clumpy head, but none of my bottled beers have.

Even though head is driven by carbonation after the pour,it's formed by dissolved protiens in the beer.

I realize that I have given life to this zombie thread but I couldn't help but comment. I was Google searching for an answer to why my Oktoberfest has a sort of coagulated head to it. I found this thread and found it VERY interesting that the op had it happen to him on an Oktoberfest as well. I brew dang good beer and have been for a while now....all grain...good water chemistry...forced carbed in a keg...NEVER had a beer look like this. Taste is fine, aroma is fine...just looks weird. Haven't been able to locate online a good reason why this would happen?....
Hey, worst case get beer.

I'm going to go with uniondr's answer above--it's proteins in the beer, since it's not an infection. I can't think of what else it would be.

I've had a few commercial beers that poured out a lumpy head.

Ever notice how bubbles form in nearly continuous streams from a nucleation site in the glass? I think these clumps of bubbles just form where the stream meets the surface. Beers that are more head retaining just exhibit these better.

I'm drinking an Oktoberfest now made with munich and Vienna and it does not have these clumps. I have brewed beers in the past that have had them and didn't think much of it, but now I'm interested to hear.
