Wassailing is a Christmas tradition that has been practiced in Britain for centuries. It has its roots in a wintertime pagan custom of visiting orchards to sing to the trees & spirits in the hope of ensuring a good harvest the following season. During the orchard visit, a communal wassail bowl – filled with a warm spiced cider, perry or ale – would be shared amongst revelers.
The carol "The Twelve Days of Christmas" & Shakespeare’s "Twelfth Night" offer clues to some of the ways people celebrated Christmas in the past. Advent, a time of fasting, was observed from the 1st to the 24th of December. Christmas would then last 12 days, ending with lots of feasting & drinking on the 5th of January – the eve of Epiphany in the Christian calendar – with wassailing a key part of the celebrations.
The word Wassail expanded from being a greeting to be a term used to refer to the punch drink related to the toast. Party-goers typically visited local orchards & fruit trees, sang songs, raised a ruckus (often by banging pots & pans.
The word "wassail" is thought to be derived from the Old English "was hál", meaning "be hale" or "good health." Clebrants were wishing both the trees & their owners Good Health. Visitors were often rewarded by the orchard’s grateful owner with some form of warm, spiced alcoholic beverage from a communal "wassail" bowl or cup. Sometimes a topping of one of the longed-for apple, known as "lamb's wool," would be added.
Early Wassail reportedly resembled the ancient Roman drink hypocras, which survived into the early Middle Ages as a libation for the wealthy. The necessity of importing the wine plus ginger, cinnamon, cloves, allspice, and nutmeg from outside England made it costly.The Wassail Bowl was sometimes composed of ale instead of wine - with nutmeg, sugar, toast, ginger, and roasted crabs ; in this way the nut-brown beverage is still prepared in some old families, and round the hearths of substantial farmers at Christmas. It is also called Lambs Wool, and is celebrated by Herrick in his “Twelfth Night:”
With gentle Lambs Wool,
Add sugar, nutmeg, and ginger,
With store of ale too ;
And thus ye must doe
To make the Wassaile a swinger.”
In Lamb's Wool, ale or dark beer was whipped to form a surface froth in which floated roasted crab apples. The hissing pulp bursting from them resembled wool. Shakespeare alluded to Lamb's Wool in Midsummer Night's Dream:
Sometimes lurk I in the gossip's bowl
In very likeness of a roasted crab
And when she drinks, against her lips I bob,
And down her withered dewlap pours the ale.
Likewise in Love's Labour's Lost:
When all aloud the wind doth blow
And coughing drowns the parson's saw
And birds sit brooding in the snow
And Marian's nose looks red and raw,
When roasted crabs hiss in the bowl,
Then nightly sings the staring owl, Tu-whit,
Tu-who—a merry note,
While greasy Joan doth keel the pot.
