WASSAILING
Wassailing
The tradition of wassailing falls into two distinct categories: The House-Visiting wassail and the Orchard-Visiting wassail. The House-Visiting wassail, caroling by another name, is the practice of people going door-to-door singing Christmas carols. The Orchard-Visiting wassail refers to the ancient custom of visiting orchards in cider-producing regions of England, reciting incantations and singing to the trees to promote a good harvest for the coming year.The above text is a snippet from Wikipedia: Wassailing
