Foam pattern in pint
« on: April 23, 2014, 07:33:30 AM »
Anyone ever get this in their beer? What would be a cause of this? Is it excess proteins? I seem to get this a lot on my light lagers. Sorry for the gigantic size, not sure how to resize it and post it.

Really? Dang. I can see it, it's just very large. Let me try and resize it and post again.

EDIT: I resized it. Hopefully you can see it.

I get that every once in a while.  Don't know why.

I wonder if infection could be a cause of that?

No idea, but I don't recall the beers of mine that looked like that being infected.

Hmm. This particular beer I think may have been. It was a helles that developed a bit of a ripe fruit flavor. But I've got a helles on tap now that is also doing this that tastes fine after 5 weeks of lagering. I mean, it's an aesthetic thing, but it's weird looking and I kind of don't like it. I just wonder if there's something I can do differently to avoid it. This beer was a Hochkurz step mash, fermented at 50 with Wyeast 2278, 100% Best pils malt.
I've never seen this in commercial beers, so it makes me think something is wrong.

can see it now.

i've seen that before, but don't know the cause.  I would think fats or oils would cause that more than proteins, but lets see what some of the others say.

I've seen that in Sam Adams Boston Lager often.  i hate to say this, since I know you're not a rookie, but are you using beer clean glasses?  just wondering if some soap residue could cause that.

It's possible, but I always rinse my glass before pouring a beer.

I've seen that occasionally too.  I thought maybe it was some kind of powdery yeast that didn't flocculate well, perhaps due to poor handling?

I get that sometimes, too.  Going by memory, I believe it's typically when I have a beer with a large initial head and wind up with these floating islands when it settles.  I've assumed it's whatever proteins were in the head when it formed initially that coagulate into clumps and then get ingested.

This is what I was thinking. The beer does pour with a large head although it's not over carbonated or anything. I only seem to get it on my light lagers however, which is what confuses me.

Looks like the remains of the head to me. I see that stuff all the time- particularly on pale beers. Never really thought that much about it.
