I don't know the Law, other than in England. Here it is illegal to sell home made cider; though it can be given! During the WW2, many American servicemen would hear about Scrumpy, and try to buy it in Public Houses.They would be served a half pint of sweet cider with half a pint of dry; and told that it was Scrumpy. Even now, I have heard people say that they have drunk Scrumpy in a Bar.They haven't!
Real Scrumpy still has "bits" floating about in it; and it looks rather cloudy.Most farmers in the south of England will make it for drinking during Mabon, or at the ceremony of Wassailing.
