Generally ales, although some dark strong lagers exist. Spices are required, and often include those evocative of the Christmas season (e.g., allspice, nutmeg, cinnamon, cloves, ginger) but any combination is possible and creativity is encouraged. Fruit peel (e.g., oranges, lemon) may be used, as may subtle additions of other fruits. May use a wide range of crystal-type malts, particularly those that add dark fruit or caramel flavors. Flavorful adjuncts are often used (e.g., molasses, treacle, invert sugar, brown sugar, honey, maple syrup, etc.).
