What is this foam?

[DarrellQ]

This is an Octoberfest lager I brewed 11 days ago and it fermented vigorously at 50 degrees for a week and then I raised temp to 60 degrees for diacetyl rest for 4 days. I think krausen has dropped but I have never noticed foam like this in any past brews. I rarely brew lagers but mainly brew ales.

Just looks like kräusen to me.

Definitely krausen...definitely hasn't fallen.

But why hasn't it fallen? It reached a FG of 1.008 a week ago.

Sometimes the krausen doesn't fall on its own. Try jostling the fermenter to see if that does it.

That worked, thanks!
