I've spent too much time reading about this but read where it could be off gassing that pushes the hop particles to the top. And I thought that off gassing didn't happen if fermentation had completed but I guess I just showed more of what I don't know.
Yea, I get the oil part as the last one I did have decent head but it didn't last and I can live with that. But I can't wrap my head around why all this happened days after FG was reached.
You'd think with all the beers under my belt I would have seen a good bit by now but that's the beauty of this hobby.....each 'child' is different.
If it weren't for the semi strange taste, I don't think I would have even posted this.
I'm cold crashing in a few days and hopefully drop this out.
I guess I don't understand why having reached FG would have any bearing on this.
yup, off gassing can and usually will happen anytime there are changes in the environment, temperature fluctuations etc, regardless.
