The tradition of wassailing falls into two distinct categories: the house-visiting wassail and the orchard-visiting wassail. The house-visiting wassail is the practice of people going door-to-door, singing and offering a drink from the wassail bowl in exchange for gifts; this practice still exists, but has largely been displaced by carol singing. 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. Notable traditional wassailing songs include "Here We Come a-Wassailing", "Gloucestershire Wassail", and "Gower Wassail".

Cider is an alcoholic beverage made from the fermented juice of apples. Cider is widely available in the United Kingdom and Ireland. The UK has the world's highest per capita consumption, as well as the largest cider-producing companies. Ciders from the South West of England are generally higher in alcoholic content. Cider is also popular in many Commonwealth countries, such as India, South Africa, Canada, Australia, and New Zealand. As well as the UK and its former colonies, cider is popular in Portugal, France, Friuli, and northern Spain. Germany also has its own types of cider with Rhineland-Palatinate and Hesse producing a particularly tart version known as Apfelwein. In the U.S. and Canada, varieties of alcoholic cider are often called hard cider to distinguish it from non-alcoholic apple cider or "sweet cider", also made from apples. In Canada, cider cannot contain less than 2.5% or over 13% absolute alcohol by volume.
