Wheat Foam

[Smokee]

I'm trying a new AG, pitched the first bucket last night. This morning when I check before going to work I found it pushed foam up through the airlock & up the latex hose into my "mash exhaust" pvc system then back down into two other airlocks I had going. I'm trying a wheat mash, about 65% wheat, first time using that much. The mash turned out really well, I'm surprised at the amount of foam though. I have another to pitch tonight, I'm going to make some kind of slobber box to keep the foam out of the exhaust.
