Well I've fought this battle a few times and Wyeast 3787 always wins. There is no defeating this crazy fucking yeast. This always results in super thick blow off yeast chunks every where. More head space, it doesn't matter, more fermcap, it doesn't matter. there is not way around it, It makes play dough babies all over by chest freezer every time. That is my experience anyway. I've got a starter going now that keeps oozing out from the stir plate.
I've made the paters biere from NB and it's great, I'm brewing a Belgian dubbel with it next and I'm sure it will mess up my chest freezer again...
