I just opened up my DFH aprihop clone, after 8 days in the primary. It has a real heavy brown and white foam on top. Checked the FG its at 1.010. The recipe says FG should be around 1.014. My question is should I let it sit for another week to let the foam disappear. This is my 8th brew and all other have been foam free within the first week. No visible airlock activity and the dry yeast I am using is Safale US-05. The air temp is around 72F. Any suggestions????
