Glögg is the term for mulled wine in the Nordic countries. The main classic ingredients are (usually) red wine, sugar, spices such as cinnamon, cardamom, ginger, cloves and bitter orange, and optionally also stronger spirits such as vodka, akvavit or brandy.
To prepare glögg, spices and/or spice extract are mixed into the wine, which is then heated to 60°-70° Celsius (140°-158° Fahrenheit). The temperature should not be allowed to rise above 78.4° Celsius (173.12° Fahrenheit) in order to avoid evaporation of the alcohol. When preparing home-made glögg using spices, the hot mixture is allowed to infuse for at least an hour, often longer, and then reheated before serving. In Sweden ready-made wine glögg is normally sold at Systembolaget ready to heat and serve, and not in concentrate or extract form. Glögg is generally served with raisins, blanched almonds and Ginger biscuits (Ginger Snaps), and is a popular hot drink during the Christmas season.
All over Scandinavia 'glögg parties' are often held during the month before Christmas.[2] In Sweden, ginger bread and lussebullar (also called lussekatter), a type of sweet bun with saffron and raisins, are typically served. It is also traditionally served at Julbord, the Christmas buffet. (Wikipedia)
