I have a honey wheat that has been in bottles for about a month now. When I open some of the bottles, the head flows out at a stead pace, not rushing, but forcing a drink of foam quite often. The pour itself produces much head. Is this an infection or is something else at work here? Reason being, I changed my sterilization technique to cooking the bottles for 1 hour at 350 F while covered with aluminum foil while they cooled and am wondering if I didn't do something correct ( ie aluminum wasn't fully secured, too many bottles, etc.)
