Wassail (/ˈwɒsəl/, /-eɪl/ WOSS-əl, -ayl) is a beverage made from hot mulled cider, ale, or wine and spices, drunk traditionally as an integral part of wassailing, an ancient English Yuletide drinking ritual and salutation either involved in door-to-door charity-giving or used to ensure a good harvest the following year.[1][2]
A wassail can be performed on any date between Christmas Eve and Old Twelfth Night (January 17).
At Christmastide too, a second group of celebrants sang their own carols--wassail carols.
