So I have been drinking a Dunkel Weiss Bier I made a little over a month and a half ago. This was my 8th brew to date and I think it tastes the best of everything I've made. The problem is it has no head on it. Out of the bottle it will sometimes come up to the top and once in awhile even start to flow over but in the glass nothing. Different styles of glasses don't effect it either. Still no head. Is this normal for this type or is something missing? I did cold crash it (35ish) for a few days before bottling.
