Breweries in the US, UK, Belgium and other countries have been producing seasonal winter or Christmas beer for awhile now. They are typically of a higher degree and sometimes include wintery spices like cinnamon, clove, nutmeg and orange peel. Higher-degree beers are made with more malt, and the increase in sugar creates a beer with a higher alcohol content. So, it seems the main purpose of a Christmas beer is to provide just a little extra warmth during the long, cold winter.
