Foam and green stuff...

[craftymcbeer]

So I brewed a Pale Ale yesterday around 4 and when I went to check on it around 11 this morning there was a layer of foam blotched in large patches by green stuff. So my question obviously is, what is it?

It looks to me like
A: Krausen, the foam that comes with fermenting beer.
B: The green stuff is hop particles. Looks like you used pellet hops without a hop bag.

If so, it's nothing to worry about. After fermentation all of that sediment will drop to the bottom of your ferm vessel and be left behind when you siphon.

I have a Cali Common fermenting right now that looks a lot like that. The 1oz of Northern Brewer at flame out seem to be riding the krausen

thanks so much for the replies I was very worried it was mold and I had managed to spoil it.

Okay so now you've brought up a second question actually. Should I try to mix the hops "riding" the krausen back into the brew?

 

[craftymcbeer]

Oh and a third question lol. If I do mix the hops back in would it then be dry hopping by accident?

 

[MeatyPortion]

I would just leave it as is. Mixing the hops into the brew isn't going to do anything except increase the risk of infection since you'll have to take the airlock off while doing so.

I think you just need to leave it alone, until it falls.

Just leave it. As it ferments, it'll mix itself up a bit as well as gravity helping you out.

Okay thanks again!
