Heineken invites you to discover the Fischer Christmas brew with a surprising mulled beer recipe.

It is said that In the 17th century beer was served at room temperature or warmed in a bowl to develop its digestive properties. In the following century, beer in taverns was served warmed and flavored with cloves and spices. There was a beer-warming apparatus that consisted of a metal tube that was filled with boiling water, closed up, and immersed into the beer. Heineken lets you rediscover this tradition with Fischer 2010 Christmas beer. The brew has an amber color, creamy head, aromatic aromas of spice and fruit, and a flavor combining sweetness, a touch of acidity and slight bitterness with overtones of cinnamon, citrus and caramel: a beer perfectly suited for mulling.

1. Wash the citrus fruits.
2. In a saucepan, combine the sugar, water, spices and grated citrus zests.
3. Boil for 1 minute, then add the lime juice off the heat.
4. Infuse for 10 minutes and strain.
5. Heat 250 ml (1 cup) Fischer Christmas beer to room temperature in a 900 W microwave for 1 minute to prevent foaming.
6. Pour 60 g (1/4 cup) of the syrup into the beer and serve.
